SURPRISE, Ariz. -- Rangers outfielder Shin-Soo Choo, who has been sidelined with tightness in the triceps muscle of his left arm, was back on the field Monday.
Choo was used at designated hitter in a Triple-A game against the Mariners and led off five straight innings. The opposing pitcher was Hisashi Iwakuma, who was getting his work in because the Mariners were playing the Angels.
Choo was 3-for-5 with two doubles, playing for the first time since an intrasquad game on Friday.
"The first at-bat was a swing and miss three times," Choo said. "But I kept seeing the ball. I hadn't played in a game in a few days, so the first at-bat felt weird. After that I felt better."
Choo has played in just six Cactus League games and is 4-for-18. He normally gets 55 to 60 at-bats in the spring, so he would like to pick it up in the final two weeks of camp.
"I'm not worried about it, but it makes me feel more comfortable," Choo said. "We've still got games left."
Choo is shut down from throwing. He is expected to begin a light throwing program on Thursday and still insists he will be ready to play right field on Opening Day.
