Baseball America Maps Where Every Top 100 Prospect Starts 2026 Season

Baseball America is tracking the Opening Day assignments for all Top 100 Prospects to start the 2026 season, with MLB games kicking off this week, Triple-A Opening Day on Friday, and the rest of the full-season minor leagues getting underway next week. The result is the most comprehensive single-stop prospect placement guide of the year, and the early returns reveal a pipeline loaded with elite talent scattered across every level of professional baseball.

This year's preseason Top 100 is the 37th edition of Baseball America's flagship prospect ranking, built on year-round efforts to capture both how prospects are perceived by the industry presently and who will produce in the future, with construction involving industry feedback from MLB scouts, coaches, analysts, and front office officials.

Players are eligible for the Top 100 if they have not exceeded 130 MLB at-bats, 50 innings pitched, or 30 pitching appearances, and prospects who have yet to accrue at least 45 days of active MLB service are also eligible for inclusion.

Here is where every Baseball America Top 100 prospect is expected to begin the 2026 season.

MLB Roster

1. Nolan McLean, RHP, New York Mets

Electric Mets righthander Nolan McLean needs only 2.1 more innings before he eclipses the eligibility threshold, which tells you everything about how close his prospect status is to expiring. McLean is the best pitching prospect in baseball and enters 2026 as the game's top pitching prospect, the latest milestone in his meteoric rise from a talented two-way player at Oklahoma State to the front of the Mets rotation.

2. Dylan Beavers, OF, Baltimore Orioles

Orioles outfielder Dylan Beavers needs just two days of active service time before he graduates from prospect status entirely, making his Opening Day spot on the Baltimore roster both an earned reward and a near-certain farewell to his prospect designation.

3. Samuel Basallo, C, Baltimore Orioles

Samuel Basallo, Beavers' Orioles teammate, needs just three days of active service time before he graduates. His presence alongside Beavers on the Baltimore MLB roster is a remarkable testament to the organization's catching development pipeline.

4. Parker Messick, LHP, Cleveland Guardians

Guardians lefty Parker Messick will lose his eligibility after just six days of active service time or 10.2 innings. Cleveland's decision to open with him on the active roster reflects confidence in his readiness to contribute at the highest level immediately.

5. Bubba Chandler, RHP, Pittsburgh Pirates (No. 11)

Bubba Chandler (No. 11), Connelly Early (No. 56), and Justin Crawford (No. 53) are all holding big-league jobs to start 2026, showing that several clubs are ready to trust young players in meaningful roles. Chandler in particular is a fascinating case: a two-sport, two-way high schooler who could have gone to Clemson for baseball and football, he signed for $3 million as the first pick in the 2021 third round and was developed as a two-way player for parts of two seasons before focusing on pitching beginning in 2023.

6. Connelly Early, OF, (No. 56)

Early's spot on a big-league roster to begin 2026 makes him one of the youngest outfielders in the majors at the start of the season. His jump to the Show validates a breakout minor league trajectory that accelerated faster than most front offices anticipated.

7. Justin Crawford, OF, (No. 53)

Crawford opens on an MLB roster as one of the faster-developing outfield prospects in the game. His Opening Day assignment confirms that his parent club views him as a legitimate contributor rather than a player in need of further seasoning.

8. Andrew Painter, RHP, Philadelphia Phillies (No. 28)

Andrew Painter (No. 28) holds a big-league job to start 2026, a remarkable story given the injury history that once threatened to derail his trajectory entirely. Philadelphia's rotation is better for it.

9. JJ Wetherholt, INF (No. 5)

No. 5 JJ Wetherholt is among the rookies making the jump to the major leagues to begin 2026. Wetherholt is considered one of the game's best prospects because of what feels like a preternatural feel to hit, and more than enough other skills to challenge for NL Rookie of the Year in 2026.

10. Carson Benge, OF (No. 16)

No. 16 Carson Benge is among the rookies making the jump to the big leagues to start the 2026 campaign. Benge's assignment confirms he has done everything asked of him in the minors and his parent club is ready to see what he can do in real games that count.

Triple-A

11. Konnor Griffin, SS, Pittsburgh Pirates (No. 1) - Triple-A Indianapolis

Konnor Griffin, the consensus No. 1 prospect, will open the season at Triple-A Indianapolis. Griffin was drafted ninth overall in 2024 and slashed .333 BA across 484 at-bats with 21 home runs and 65 stolen bases while reaching Double-A in his first full professional season. Griffin is the highest-ranked Pirates player in the history of the Baseball America Top 100, surpassing even Gerrit Cole and Paul Skenes in that regard.

12. Colt Emerson, SS (No. 9) - Triple-A

Colt Emerson (No. 9), Max Clark (No. 10), and Walker Jenkins (No. 14) headline the Triple-A group, players who are just one call away from making an impact in the majors.

13. Max Clark, OF, Detroit Tigers (No. 10) - Triple-A

Clark is a five-tool talent and the top center field prospect in baseball. After hitting .271/.403/.432 across stints at High-A and Double-A, Clark enters 2026 with a shot to debut later this summer. In a normal year he would have been the first overall pick out of high school, but in the loaded 2023 draft class he settled for third overall and a nearly $7.7 million bonus.

14. Walker Jenkins, OF (No. 14) - Triple-A

Jenkins joins the deep Triple-A outfield group that headlines this year's highest-level minor league assignments. His tools profile as a potential above-average regular in center field at the next level.

15. Kevin McGonigle, INF (No. 2) - Triple-A

McGonigle's career minor league stat line is .308/.410/.512 with 25 homers and 40 stolen bases in 183 games, and he is projected to spend the 2026 season mostly in Triple-A, though it would not surprise observers if he bursts through the door to the big leagues. Baseball America awarded him an 80 grade for his hit tool, one of the rarest grades in prospect evaluations.

16. Luis Peña, INF/OF (No. 26) - High-A Wisconsin

Luis Peña (No. 26) heads to High-A Wisconsin, making him one of the higher-profile prospects assigned below Triple-A. Peña was clocked with a pair of sprint speeds at 30-plus feet per second on ground outs during Spring Breakout, signaling elite athleticism that will play at any level.

17. Eli Willits, SS, Washington Nationals (No. 13) - Single-A Fredericksburg

Eli Willits (No. 13) gets his shot at Single-A Fredericksburg. The son of former Angels outfielder Reggie Willits, Eli reclassified to 2025, was 17 on draft day when the Nationals made him the first overall pick for $8.2 million, and was assigned to Low-A Fredericksburg late in 2025, where he slashed .300/.397/.360 in his professional debut.

18. Sebastian Walcott, SS - Injured List

Nine Top 100 prospects landed on the injured list as spring wrapped up. Sebastian Walcott had internal brace surgery, while Travis Sykora is rehabbing from Tommy John surgery. Both players face uncertain timelines for their returns, which could meaningfully shift when they are expected to debut at the major league level.

19. Travis Sykora, RHP - Injured List

Sykora's Tommy John recovery puts his 2026 timeline in significant doubt. The strikeout-heavy arm was considered one of the more advanced pitching prospects before the injury, and the development clock effectively resets while he works his way back.

The Broader Picture: Level-by-Level Breakdown

20. Triple-A group (29 prospects total)

Triple-A will see 29 Top 100 prospects at the start of the Minor League season, a strong indicator of the depth teams have built up across baseball. This is the largest single-level cluster in the tracker, and it features several players who could realistically be called up before the All-Star break.

21. Double-A group (18 prospects total)

Double-A will feature 18 Top 100 prospects at the start of the season. This cohort represents the next wave: players close enough to smell the majors but still being refined against the game's most competitive minor league pitching and hitting environments.

22. MLB Opening Day group

Twenty members of MLB Pipeline's Top 100 started the season on big-league rosters, a sign that a wave of young talent is ready to make an impact. Across Baseball America's tracker, several of those same players appear, underscoring how convergent the major evaluating outlets are on this year's group.

Team-by-Team Concentration

23. Boston Red Sox - 4 prospects

The Boston Red Sox are among ten organizations with four Top 100 prospects on Baseball America's 2026 list. That quartet gives Boston one of the most enviable pipelines in baseball entering the new season.

24. Detroit Tigers - 4 prospects

The Detroit Tigers carry four Top 100 prospects on the Baseball America list, headlined by Max Clark at Triple-A. The Tigers' rebuild has been aggressive and the 2026 assignments reflect how close that talent is to arriving.

25. Los Angeles Dodgers - 4 prospects

The Dodgers have four Top 100 prospects and have now maintained a streak of at least three players on the Top 100 for 12 consecutive years. No other organization has matched that consistency across that same time span.

26. Minnesota Twins - 4 prospects

Minnesota carries four Top 100 prospects into the 2026 season. The Twins have built quietly through the draft and international pipeline, and their assignment map reflects a methodical, level-appropriate approach to development.

27. New York Yankees - 4 prospects

The New York Yankees have four prospects on Baseball America's Top 100, continuing a run of elite organizational depth. New York's ability to develop and trade from that depth remains one of the defining front-office stories of the mid-2020s.

28. Pittsburgh Pirates - 4 prospects

Pittsburgh carries four Top 100 prospects, with Konnor Griffin at the summit of the entire list. The Pirates have accelerated their rebuild faster than the market expected, and their prospect concentration is a primary reason.

29. San Francisco Giants - 4 prospects

San Francisco has four Top 100 prospects on the Baseball America tracker. The Giants' front office has leaned heavily on international scouting and draft strategy to rebuild organizational depth after a transitional phase.

30. Seattle Mariners - 4 prospects

The Seattle Mariners have four Top 100 prospects entering 2026. Ryan Sloan headlines that group after a spectacular Spring Breakout showing. Sloan maxed out at 99.5 mph during his lone appearance in major league camp, topping his 2025 maximum of 98.8 mph.

St. Louis has four Top 100 prospects on the Baseball America list. The Cardinals' prospect pipeline has been replenished through a combination of draft investment and international signings, and the Opening Day assignments show a group spread across multiple levels.

32. Tampa Bay Rays - 4 prospects

Tampa Bay rounds out the group of organizations with four Top 100 prospects. The Rays' player development model remains one of the sport's gold standards, and their assignment tracker reflects the characteristic patience with which they manage player timelines.

33. Athletics - 3 prospects

The Athletics carry three Top 100 prospects on the Baseball America list. As the organization continues its transition, the prospect depth provides a foundation for the next competitive window.

34. Cincinnati Reds - 3 prospects

The Cincinnati Reds also have three Top 100 prospects beginning the 2026 season. The Reds have been one of baseball's most active development organizations in recent years and the assignments spread across multiple levels.

35. Toronto Blue Jays - 3 prospects

Toronto has three Top 100 prospects on the Baseball America tracker, a group that reflects a mid-rebuild organization with immediate MLB contributors mixed with longer-range developmental bets.

36. Washington Nationals - 3 prospects

Washington carries three Top 100 prospects, with Eli Willits the most high-profile name. The Nationals invested the No. 1 overall pick in 2025 to anchor their rebuild, and the assignment tracker shows they are managing his development conservatively.

37. Arizona Diamondbacks - 2 prospects

The Arizona Diamondbacks have two Top 100 prospects on the Baseball America list. Arizona's competitive window at the MLB level is partially funded by the prospect capital it has retained rather than traded.

38. Atlanta Braves - 2 prospects

Atlanta carries two Top 100 prospects entering 2026. The Braves have operated near the top of the standings while still maintaining prospect equity, a balance few contending organizations sustain.

39. Chicago Cubs - 2 prospects

The Cubs have two Top 100 prospects on the list. Chicago's front office has prioritized rebuilding the pipeline after trading from organizational depth during recent competitive windows.

40. Kansas City Royals - 2 prospects

Kansas City carries two Top 100 prospects as it continues to build around its young core. The Royals' development investment over the last several seasons is beginning to yield meaningful results at the upper minor league levels.

41. Philadelphia Phillies - 2 prospects

Philadelphia has two Top 100 prospects, with Andrew Painter headlining the group on the MLB roster. The Phillies are in full contention mode, making the presence of top prospects on the big-league club a luxury rather than a necessity.

42. Texas Rangers - 2 prospects

Texas carries two Top 100 prospects on the Baseball America tracker. The Rangers' prospect pipeline has been partially depleted by trades that fueled their 2023 World Series run, but the two remaining names represent legitimate upside.

43. Colorado Rockies - 1 prospect

Colorado has just one Top 100 prospect on the Baseball America list. For an organization with a significant rebuilding task ahead, a single Top 100 representative reflects the challenge of developing elite talent at altitude.

44. Los Angeles Angels - 1 prospect

The Angels carry one Top 100 prospect into the 2026 season. Los Angeles has been one of baseball's most scrutinized rebuilding organizations, and the tracker's single entry underscores how much ground the Angels still need to cover.

45. San Diego Padres - 1 prospect

San Diego has one Top 100 prospect on the list. The Padres have operated with an aggressive MLB payroll while trading from organizational depth, and the tracker reflects that philosophy.

46. Houston Astros - 0 prospects

In a stunning organizational footnote, this is the first year since the Top 100's inception in 1990 that the Astros do not have a prospect ranked on the list. It is a remarkable data point that captures the full cost of Houston's sustained championship run, which required trading nearly every significant piece of prospect capital the organization produced.

Positional Breakdown

47. Shortstop dominance: 28 prospects

The 28 shortstops on the 2026 list are the most ever, easily topping the previous high of 24 in 2022. Until the 2020s, there had never been 20 shortstops in the Top 100, and a strong high school shortstop draft class helped drive this surge, with Eli Willits, Dax Kilby, JoJo Parker, Ethan Holliday, Billy Carlson, and Kayson Cunningham all making the list.

48. Third base: just 1 prospect

The one third baseman on the 2026 list is the smallest number ever for the position, with the high having been 12 back in 2012. The near-disappearance of third base prospects from the Top 100 is one of the most striking structural shifts in how organizations are building and evaluating their talent pipelines.

49. Second base: just 1 prospect

The one second baseman on the 2026 list is the second-lowest number for the position, as only 1992 had no players listed primarily at second base. The shift of middle infield talent toward shortstop in the draft and development pipeline is directly reflected in this number.

50. Dax Kilby, SS - High School Shortstop Class

Dax Kilby is one of the 2025 first-round prep picks who helped push the Top 100 shortstop count to 28. His assignment for 2026 represents one of the lower-level placements on the tracker, consistent with a player who has barely begun his professional career.

51. JoJo Parker, SS - High School Shortstop Class

JoJo Parker is among the prep shortstops from the 2025 class who contributed to the record shortstop count on the 2026 Top 100. Parker's assignment will be monitored closely by scouts tracking whether his defensive profile holds up as he moves through the low levels.

52. Ethan Holliday, SS - High School Shortstop Class

Ethan Holliday is another 2025 first-round prep pick who made the Top 100 and pushed the shortstop count to an all-time high. His surname carries significant baseball legacy, and his development will be one of the more closely watched storylines of the 2026 minor league season.

53. Billy Carlson, SS - High School Shortstop Class

Billy Carlson rounds out the group of 2025 prep first-round picks who made the Top 100 at shortstop. His Opening Day assignment reflects where his organization believes he fits developmentally after a brief professional introduction in 2025.

54. Kayson Cunningham, SS - High School Shortstop Class

Kayson Cunningham is the sixth prep shortstop from the 2025 draft class on the Baseball America Top 100. Collectively, this group of teenagers at shortstop represents an extraordinary concentration of drafted talent at a single position in a single class.

Injury-Affected Assignments

55. Injured prospects (9 total)

Nine Top 100 prospects landed on the injured list as spring wrapped up, with several notable rehab cases keeping a close eye on their return timelines. Injuries can easily shift when a prospect might debut in the majors and also make a team's internal depth even more important, especially if early-season setbacks pile up.

Prospects Near Graduation

56. Five prospects could exit the Top 100 within the first week

Five players could exit the Top 100 within the first week of the season alone, leaving room for a quintet of new prospects to join the list, with plenty of talented players percolating in the minor leagues waiting to take their place.

57. The list is updated throughout the season

Baseball America publishes in-season updates throughout the year to account for looming graduations, injuries, and other performance-based changes to the Top 100. This means the opening-day snapshot is a living document rather than a fixed roster, with turnover expected as early as the first series of games.

58. Jesus Made, OF, Milwaukee Brewers - upper minors

Jesus Made has made it all the way to Double-A in his first taste of stateside baseball and could very well see time with the Brewers in 2026 if all things break right. His assignment places him firmly in the mix to become one of the year's most important prospects to watch as the season progresses.

59. Ryan Sloan, LHP, Seattle Mariners - upper minors

Sloan projects as a No. 2 starter and is on the short list of minor leaguers even in the conversation for a No. 1 projection. His spring velocity spike to 99.5 mph adds a dimension to his arsenal that makes his 2026 assignment one of the most exciting on the entire tracker.

60. Jonny Farmelo, OF - upper minors

Jonny Farmelo hit a 112.4 mph single off Bishop Letson during Spring Breakout, producing the hardest-hit ball of any Top 100 prospect during the spring showcase. His assignment to begin the 2026 season places him on a trajectory to challenge for a big-league debut before season's end.

61. The rookie class overall

Loaded with Top 100 Prospects, the 2026 rookie class looks like one of the best this century. The Opening Day assignment tracker is the first definitive evidence of that claim playing out in real time, with prospects at every level poised to make their marks on the 2026 season.

62. Chase Petty, RHP - upper minors

Chase Petty led all pitchers on the first day of Spring Breakout with a 102.1 mph fastball, and Miguel Sime Jr. topped out at 101.9 mph and topped 100 mph nine times. Both arms are among the most watched pitching assignments on the tracker this spring.

63. Miguel Sime Jr., RHP, Washington Nationals - upper minors

Miguel Sime Jr. topped out at 101.9 mph during Spring Breakout and generated up to 20 inches of induced vertical break on his fastball. His assignment will be one of the most scrutinized on the entire tracker given the premium the industry places on his combination of velocity and movement.

64. Marco Raya, RHP - bullpen role

Marco Raya enters 2026 in a full-time bullpen role for the first time in his career and showed electric stuff during Spring Breakout, recording three whiffs with his sweeper at 86-87 mph, including an 86.9 mph offering with 16 inches of horizontal break at 2,700 rpm.

65. Gavin Cross, OF - upper minors

Gavin Cross smashed a 110.1 mph home run during Spring Breakout, one of the hardest-hit balls by any prospect this spring. His assignment to begin 2026 places him in an upper-minors group with a realistic shot at a midseason call-up if he sustains that kind of contact quality.

66. Mitch Jebb, INF, Pittsburgh Pirates - upper minors

Mitch Jebb had a 109.5 mph triple and showcased elite speed during Spring Breakout, flashing the kind of multi-tool profile that makes him one of the more intriguing mid-tier prospects on the Pittsburgh pipeline.

67. Leomar Rosario, RHP, Houston Astros - minors

Leomar Rosario had four pitches clocked at 100.0 mph or harder during Spring Breakout, topping out at 100.2 mph, making him a notable name on the tracker despite playing for the only organization without a prospect on the Baseball America Top 100. His assignment will be monitored as a potential future entrant on the list.

68. Yorger Bautista - upper minors

Yorger Bautista tagged a 110.2 mph triple during Spring Breakout, showing the kind of raw power that makes him one of the more compelling position player assignments on the tracker heading into the regular season.

69. The list is built on year-round scouting infrastructure

Construction of the Top 100 involves industry feedback from MLB scouts, coaches, analysts, and front office officials, with players watched in person as often as possible. The list also relies on extensive reporting done to produce Top 30 Prospects rankings and the Baseball America Prospect Handbook.

70-100. The remaining 31 prospects on Baseball America's tracker span every level of the minor league system, from Low-A to Triple-A, with their assignments continuously updated as the new season gets underway and Baseball America compiles Opening Day assignments for every player, denoting those with injuries keeping them from starting the season and staying tuned for updates as more information becomes public. From front offices making service time calculations to fantasy managers finalizing dynasty rosters, this tracker is the definitive reference point for the 2026 prospect landscape. The sheer volume of elite talent assigned to Triple-A alone suggests the second half of 2026 will be one of the most prospect-rich debut seasons in recent memory.
