CLEVELAND, July 13 (UPI) -- The New York Yankees placed righthander Roger Clemens on the 15-day disabled list Saturday with a strained right groin.
Clemens re-aggravated his injured groin after pitching five scoreless innings in Friday's loss to the Cleveland Indians. He took the mound to start the sixth inning but left after throwing a few warmup pitches.
Clemens is 8-3 with a 4.02 ERA in 18 starts this season but has not recorded a victory since June 9 after winning eight of his first 14 outings. He is second in the American League with 126 strikeouts.
The six-time Cy Young Award winner is the active career leader in wins (288), starts (556), innings (3,996 2/3) and complete games (116). He needs one win to surpass Tommy John for sole possession of 21st place all time.
Clemens' injury gives the Yankees added time to decide between Orlando Hernandez and Jeff Weaver, both of whom are competing for the fifth spot in the rotation.
Weaver, who was acquired in a three-way trade with Oakland and Detroit on July 6, started for New York last Sunday, giving Clemens the opportunity to rest his groin until after the All-Star break.
The Yankees recalled pitcher Mike Thurman from Class AAA Columbus to take Clemens' spot on the active roster.
Thurman is 1-0 with a 7.62 ERA in four appearances for New York this season, including two starts. New York purchased Thurman's contract from Columbus on May 23 before returning him to the minors on June 26.
The 28-year-old righthander is 26-36 with a 5.11 ERA in 97 career appearances over six major league seasons.
