SURPRISE, Ariz. -- On Friday, Shin-Soo Choo said health was most important for him this year. One day later, the Rangers announced that Choo would be sidelined for at least a couple days with tightness in the triceps muscle of his left throwing arm.
Rangers assistant general manager Thad Levine said Saturday the issue is not considered serious and Choo may be able to be used at designated hitter as early as Sunday. But Choo also had surgery on Aug. 29 to have a bone spur removed from his left elbow.
Levine said Choo may have been doing too much throwing, which possibly caused the triceps tendinitis.
"We trust our medical staff to let us know when we should feel alarmed, and they haven't give us that impression," Levine said. "Shoo is an exceptionally hard worker, and he threw a ton in the offseason.
"He is an extremely important player to us, so we're going to monitor him. He should be able to DH soon and be back in right field in plenty of time to get ready for the regular season."
Choo has played in six Cactus League games and is 4-for-18 at the plate. He had four plate appearances in a "B" game on Friday.
