ARLINGTON -- The Rangers have placed outfielder Carlos Gomez on the disabled list because of the cyst in the back of his right shoulder and have called up infielder Phil Gosselin from Triple-A Round Rock.
Gomez developed the cyst last Sunday and had a procedure Friday to have it cleaned out. He was placed on the disabled list retroactive to Aug. 16 and will be eligible to come off Aug. 26 in Oakland.
"Everything is good," Gomez said. "We just have to wait for the stitches. If I have to do something, it might open it up again. But everything is feeling much better."
Gosselin is a five-year veteran who was claimed on waivers from the Pirates on Aug. 12 and was 2-for-13 with Round Rock before being promoted. He was 6-for-40 (.150) in 28 games for the Pirates this season. He has previous big league experience with the Braves and D-backs with a career batting average of .272 with a .320 on-base percentage and a .368 slugging percentage.
He has the versatility the Rangers crave as he has played all four infield positions plus left field in his Major League career. Most of his time has been at second base.
He was called up so that Drew Robinson could be available in a starting role rather than being used carefully as the Rangers' primary utility player.
"It frees up Drew to play all over," Rangers manager Jeff Banister said. "We were pretty heavy on outfielders and pretty light on infielders."
Mazara used at designated hitter
Nomar Mazara was back in the lineup Saturday, one day after banging his left knee against the outfield wall Friday night against the White Sox. But Mazara was only at designated hitter with Shin-Soo Choo starting in right field.
"That's me," Banister said. "The medical staff said he was fine and Mazara said he was fine. It's me being cautious. It's the first time the guy has been through anything like that."
Mazara banged the knee crashing into the wall in the eighth inning Friday night trying to run down Nicky Delmonico's deep drive. Mazara couldn't make the catch and instead banged hard into the wall. He was able to stay in the game and said he woke up without any soreness in the knee that would keep him out of the lineup.
Rangers beat 
• Keone Kela, who has been on the disabled list retroactive to Aug 5 with a sore right shoulder, has started throwing again. Kela played catch on Friday and Saturday.
• Derek Holland, who started Saturday for the White Sox, was only the second left-handed starter the Rangers have faced in the last 14 games.
• Nick Martinez pitched eight scoreless innings in Round Rock's 3-0 win over New Orleans on Friday night. He has not allowed a run in his last 24 innings at Round Rock and Banister said, "You've got to be throwing the ball well to put up zeros like that. There is some significance to it."
