Houston, TX (SportsNetwork.com) - The Texas Rangers officially placed pitcher Martin Perez on the 15-day disabled list among a flurry of roster moves made prior to Wednesday's game against the Houston Astros.
Perez, who is dealing with inflammation in his left elbow, was put on the DL to make room for Nick Tepesch to start Wednesday's finale of a three-game series from Minute Maid Park.
The Rangers also purchased the contract of veteran hurler Scott Baker from Triple-A Round Rock while designating pitcher Justin Germano for assignment.
Perez has struggled mightily in each of his last three starts, having been tagged for 19 runs and 24 hits over a combined 13 1/3 innings while losing all three outings. The young lefty had gone 4-0 with a 1.42 ERA through his first five mound trips of the season.
The 23-year-old was rocked for six runs and nine hits while lasting just 3 1/3 innings in a loss to Boston this past Saturday.
Tepesch earned a promotion by going 6-1 with an impressive 1.58 ERA in seven starts for Round Rock. The 25-year-old right-hander made 17 starts and a pair of relief appearances for Texas as a rookie last season, compiling a 4-6 record with a 4.84 ERA.
Baker, a 15-game winner for Minnesota in 2009, allowed two runs in a 5 1/3- inning relief stint for the Rangers on May 7 and was designated for assignment the next day. He has posted a 4-1 record with a 3.32 ERA in six starts for Round Rock.
The 32-year-old missed nearly all of the previous two seasons while recovering from Tommy John surgery.
Germano had been tagged for seven earned runs over 5 1/3 innings in a pair of relief appearances with Texas.
