The Texas Rangers activated right-handed reliever Cole Winn from the 15-day injured list on Tuesday after he was sidelined since May 23 by arm fatigue.

Winn, 26, takes the spot on the 26-man roster vacated by right-hander Luis Curvelo, who was optioned to Triple-A Round Rock on Sunday.

Winn allowed two runs on two hits in a third of an inning of his most recent outing that came during a 5-2 loss to the host Los Angeles Angels. He exited the game after three batters with fatigue and soreness in his right shoulder.

In 22 appearances this season, he is 2-1 with one save, a 5.59 ERA, seven walks and 23 strikeouts in 19 1/3 innings.

In 68 career relief appearances, Winn is 2-3 with one save, a 3.91 ERA, 28 walks and 72 strikeouts in 78 1/3 innings.

Texas made Winn the 15th overall selection in the 2018 MLB Draft.

Curvelo, 25, had a scoreless inning Sunday in the Rangers’ 10-0 victory over the visiting Guardians. He has a 4.91 ERA, two walks and four strikeouts in 7 1/3 innings over seven relief appearances.

He was on the 15-day injured list with a right biceps strain from April 15 to May 19.

In 24 career relief appearances since 2025, Curvelo is 1-1 with a 5.47 ERA over 26 1/3 innings
