10 Prospects Poised for Triple-A Roles in 2026, Baseball America Notes

A January organization-report roundup highlighted 10 prospects who appear likely to begin 2026 at Triple-A or to push for major league callups, bringing a mix of high-upside pitchers, speed merchants, and positional depth that will shape roster decisions this spring.

Michael Lombardi stands out as a unique case. The Royals draft pick who has operated as a two-way athlete is shifting to a fulltime pitching track, a move that accelerates his path to upper minors. Lombardi’s athletic profile and prior two-way experience make him an intriguing depth piece for Kansas City’s rotation and bullpen planning; a strong spring could fast-track a Triple-A assignment to test his stamina and secondary offerings against advanced hitters.

Roldy Brito earned attention after a .371 batting average and 35 stolen bases in short-season and Low-A action in 2025. Brito’s contact ability and elite baserunning project as table-setting offense at higher levels, and the Rockies could hand him a Triple-A audition to evaluate his hit tool against veteran pitching. Brito’s 2025 numbers suggest he could impact lineup construction and late-game strategies if his success carries upward.

Seaver King produced a breakout showing in the Arizona Fall League, a proving ground that pits prospects against near-major league competition. King’s AFL performance boosted the Nationals’ upper-level depth chart, positioning him as a candidate for Triple-A work where consistency against experienced pitching will determine whether he becomes a bench contributor or a depth starter option during roster churn.

Jonny Farmelo’s 2025 story was one of return and profile restoration. The Mariners prospect came back from injury with a speed-and-power combination that scouts prize. Farmelo’s health and plate timing will be the focal points in Triple-A, where the Mariners can monitor his sprint times, extra-base hit rate, and walk-to-strikeout ratio as barometers for a big league promotion.

Marco Dinges provided notable catching production for the Brewers in 2025, and catchers with offensive output carry outsized roster value. Milwaukee can deploy Dinges at Triple-A to stabilize pitching development and to create a tradeable asset or emergency option for the big league club, while also using his presence to mentor younger pitchers.

Beyond individual trajectories, these prospects matter to baseball’s business side and to minor league communities. Triple-A assignments affect 40-man planning, option years, and payroll allocations, while prospects like Brito and Dinges can drive ticket sales and clubhouse buzz in smaller markets. For front offices, these players are internal trade chips and stopgaps during injuries.

What comes next is clear: spring training and the early Triple-A season will sort prospects who can handle advanced competition from those who need more seasoning. Fans tracking callups should watch Lombardi’s inning totals, Brito’s walk rate, King’s strike-zone command, Farmelo’s recovery metrics, and Dinges’ framing and run production for signs that 2026 rosters are about to change.
