Holland left his start on Friday against the Houston Astros after only one inning because of tightness in that shoulder. It was the 28-year-old's first start of the year.
Holland dealt with some shoulder soreness during spring training, but MLB.com's T.R. Sullivan reported that Friday's injury was not in the same area.
Holland pitched in only six games last season, missing five months after tearing cartilage in his knee in the off-season and undergoing arthroscopic microfracture surgery. In 2013, his last full season, the left-hander went 10-9 with a 3.42 ERA and 189 strikeouts in 213 innings.
Rangers outfielders Shin-Soo Choo (back spasms) and Ryan Rua (sprained ankle) also left Friday's game early. The Astros won the game 5-1. Texas purchased the contract of outfielder Carlos Peguero from Triple-A Round Rock to replace Holland on the 40-man roster and also recalled pitcher Jon Edwards.
On Saturday, Texas claimed right-hander Stolmy Pimentel from Pittsburgh, who according to the Dallas Morning News will join the 25-man roster on Sunday
