Mark Lowe matched his career high with a three-inning outing on Monday, and then landed on the disabled list Friday with a strained right intercostal muscle.
Lowe said that those two things weren't related, and he's been feeling the injury for the past few weeks. Lowe has posted a 2.30 ERA over 26 relief appearances, and could be eligible to return after the All-Star break when the Rangers open a three-game series at Seattle on July 13.
"I hope that's when I'm back," Lowe said.
Lowe becomes the sixth pitcher from the Opening Day roster on the disabled list, joining Neftali Feliz, Derek Holland, Alexi Ogando, Koji Uehara and Colby Lewis.
Lowe has had a history of injury issues throughout his career. Last season, he suffered a Grade 2 left hamstring strain on Sept. 21, and did not appear again until the World Series. He was on the DL for most of the 2010 season recovering from lower back surgery. Elbow injuries plagued him in 2006 and 2007.
Reliever Yoshinori Tateyama was recalled from Triple A Round Rock to take Lowe's spot. Tateyama had one stint with the Rangers earlier this season, going 1-0 with an 11.88 ERA over seven appearances. He allowed 13 runs (11 earned) in 8 1/3 innings.
Tateyama, though, has pitched well for Round Rock since his demotion. He has thrown 4 1/3 scoreless innings with six strikeouts over four appearances.
