Rangers promote Winston Santos for MLB debut, option Jose Corniell to Triple-A
Winston Santos got the call to Texas after missing time and missing bats in Frisco. Jose Corniell went back to Round Rock, underscoring how fragile the Rangers’ pitching mix has become.
The Rangers moved Winston Santos to the majors on June 24, recalling the 24-year-old right-hander from Double-A Frisco before their series finale against the Miami Marlins at loanDepot park and optioning Jose Corniell to Triple-A Round Rock. Santos, who wears No. 47, is expected to provide bullpen protection, and if he gets into a game, it will be his major-league debut.
Texas is betting on the arm talent more than the surface line. Santos went 1-3 with a 7.44 ERA in 11 starts for Frisco this season, but he also struck out 58 batters in 42.1 innings while walking 21. Among Texas League pitchers with at least 10 starts, he ranked second in strikeouts per nine innings at 12.33, trailing only Seattle farmhand Kade Anderson. That split between run prevention and swing-and-miss stuff explains why the Rangers could justify the move now, especially with a bullpen role available.
The promotion also reflects how quickly Santos has moved from bargain signing to roster piece. Texas signed him for $10,000 out of the Dominican Republic in 2019, added him to the 40-man roster after the 2024 season, and watched him break out that year with a system-leading 11 wins and 138 strikeouts in 110 1/3 innings. He reached Double-A, pitched in the Futures Game and entered 2026 as the organization’s No. 5 prospect. MLB Pipeline’s preseason scouting report gave him a 55 fastball, a 60 slider, a 50 changeup, 55 control and a 45 overall grade.
His path has not been linear. Santos missed four months in 2025 with a stress reaction in his back, then lost more time early in 2026 after taking a comebacker off his left hand in spring training. Rangers manager Skip Schumaker said Santos impressed him in camp even without appearing in a Cactus League game, adding that he had “fight.” That edge, plus the strikeout rate, is what pushed Texas to bring him up now.
Corniell’s move back to Round Rock shows the other side of the roster equation. He already made his MLB debut with Texas on the final day of the 2025 season, and his career has also been shaped by Tommy John surgery and recovery. With Corniell down and Santos up, Texas is keeping the next wave of arms in motion while searching for the right mix behind its rotation and late-inning group.
