Rangers activate Cole Winn from 15-day injured list, optioning Luis Curvelo back to Triple-A

The Texas Rangers activated reliever Cole Winn from the 15-day injured list Tuesday, returning a right-handed bullpen arm to a staff that has been managing a steady stream of absences. Texas made room on the roster by optioning fellow reliever Luis Curvelo to Triple-A Round Rock after Sunday’s game versus Cleveland, so the move did not require any additional corresponding transaction beyond Winn’s reinstatement.

The activation came after Winn was sidelined on May 24 with right-arm fatigue. According to the Rangers’ official transaction release, he missed the minimum amount of time before becoming eligible on the club’s off day and then was formally put back onto the 26-man roster. Winn also made one rehab appearance with Round Rock on Friday at Oklahoma City, pitching 0.2 innings and allowing no hits or runs while recording a strikeout and issuing a walk.

Before the IL stint, Winn was an active part of Texas’ early-season bullpen usage. He appeared in 22 relief outings across the Rangers’ first 51 games, posting a 2-1 record with one save. His overall line through May 23 included a 5.59 ERA (12 earned runs in 19.1 innings) with 23 strikeouts and seven walks, numbers the club viewed in the context of what he had been doing in high-leverage situations and middle-relief assignments.

The Curvelo option provided the practical roster bridge. The Rangers’ release said Curvelo has worked in relief in two separate stints this season, with a combined stat line of 0-0 and a 4.91 ERA (4 earned runs in 7.1 innings) across seven appearances. Curvelo previously spent time on the 15-day injured list earlier in the year with a right biceps strain, and his most recent major-league outing was described as the Rangers’ Sunday game versus Cleveland, where he finished a 10-0 win by pitching a scoreless ninth inning.

Beyond the immediate bullpen adjustments, the Rangers’ announcement also touched other roster and rehab logistics. It said infielder Josh Smith’s injury rehab assignment was transferred from Double-A Frisco to Triple-A Round Rock, an indication that Texas continues to calibrate player availability across levels rather than relying solely on immediate activation decisions.

The team’s press release further confirmed its broader injury picture for the major league roster. After Tuesday’s transactions, Texas remained at the 40-man limit on its roster and continued to carry four players on the 60-day injured list: right-hander Carter Baumler and left-handers Cody Bradford, Robert Garcia, and Jordan Montgomery. With Winn back available, the bullpen now has one more option for middle relief and setup-style innings, though Texas still has to manage how it handles the remaining gaps.

For Rangers fans, the key question is how quickly Winn is re-integrated into established bullpen patterns after a fatigue-related absence. The immediate next test will be how manager Peterák and Texas deploy him in the highest-leverage innings over the next stretch of games, and whether Curvelo’s demotion provides the club enough depth at AAA Round Rock to keep the major-league bullpen flexible.

In the bigger picture, roster churn like this becomes a recurring theme for teams trying to sustain performance while multiple pitchers miss time. Winn’s return reduces pressure on the back end of the bullpen rotation and creates clearer options for matchups, but Texas will still need to monitor workload carefully, given the reason he went on the IL in the first place.
