Rangers option Emiliano Teodo to Triple-A Round Rock, Santos to Frisco

The Texas Rangers optioned right‑hander Emiliano Teodo to Triple‑A Round Rock and sent right‑hander Winston Santos to Double‑A Frisco, transactions posted on MLB.com and reported March 2 as part of the club’s early March roster adjustments. Teodo arrives in Round Rock with a recent history of back trouble and control issues; CBS Sports reported he "has been slow-played this spring following last season's back issues, as he's been throwing off a mound but has not appeared in a Cactus League game."

Stat lines for Teodo vary across outlets but all point to inconsistency. CBS Sports isolates his Round Rock work at a 9.00 ERA with a 23:17 K:BB over 18 innings and wrote, "He made a full-time move to a relief role in 2025 but struggled during his time with Round Rock, holding a 9.00 ERA and 23:17 K:BB over 18 innings. He's got a big arm but has strides to make with his control and durability." Lonestarball and Sports Yahoo list a broader 2025 minor‑league total of 30 innings across 27 games between the ACL, Frisco and Round Rock with a 7.20 ERA and note he also threw four innings in the Arizona Fall League. Shawn McFarland of the Dallas Morning News framed a different seasonal total, writing that Teodo "has a 7.71 ERA in 28 innings this year" and that he "walked more than one batter per inning in his stints with Round Rock and Frisco."

Teodo’s move follows a season in which the 25‑year‑old was added to the Rangers’ 40‑man roster the previous winter but struggled to stay healthy and locate strikes. Lonestarball summarized that history: "While he was seen as a dark horse candidate to make the Rangers’ bullpen out of spring training last year, he struggled to stay healthy and throw strikes all year, ultimately throwing 30 innings over 27 games between the ACL, Frisco and Round Rock, putting up a 7.20 ERA. He also threw four innings in the Arizona Fall League."

Winston Santos, who turns 24 in April and was added to the 40‑man roster after the 2024 season, was optioned to Double‑A Frisco while rehabilitating from a fractured left hand sustained when he was struck by a comebacker during batting practice. Lonestarball reported Santos "spent most of the 2025 season on the injured list, making five starts for Frisco and one start for Round Rock during the regular minor league season" and appearing in five Arizona Fall League games. On Santos’ timeline Lonestarball said, "The expectation is that Santos will be ready to go pretty soon after the minor league season starts."

Teams are permitted under roster rules to option injured players who did not appear in the major leagues the previous season, provided the player is sent down at least 15 days before the major‑league season begins, a procedural detail cited by Lonestarball and Sports Yahoo to explain the moves. Lonestarball initially noted, "The team has not formally announced those moves, though I assume they will do so today," and later appended, "EDIT — The team has officially announced these transactions." The club also assigned Nabil Crismatt, Declan Cronin and Trevor Hauver to minor‑league camp, leaving 61 players in major league camp, according to Lonestarball’s updated roster notes.

With Teodo’s health and command still in question and Santos working back from a broken hand, both options move two notable young arms down the ladder as the Rangers finalize their spring camp roster ahead of the regular season. CBS’s update on Teodo concluded that "It's unclear whether he will be ready to go at the beginning of the minor‑league season," leaving Round Rock and Frisco to monitor both pitchers’ recoveries and early‑season availability.
