The Rangers will likely be without outfielder Shin-Soo Choo for the next two games against the Athletics after he sprained his left ankle trying to beat out a base hit in the seventh inning on Monday night.

X-rays were negative but Choo was pretty sore after the game. He will have an MRI on Tuesday.

"I hit the bag hard," Choo said. "I don't know what happened but I wasn't comfortable and didn't want to make it worse."

Choo smacked a grounder that hit off pitcher Fernando Abad and caromed toward third baseman Josh Donaldson. Choo was originally called safe on a close play but the call was overturned after a challenge by Athletics manager Bob Melvin. It appeared that Choo landed awkwardly on the base while trying to beat the throw. Michael Choice took over in left field in the bottom of the inning.

Choo will likely get Tuesday and Wednesday off. The Rangers are off on Thursday so the best case scenario is likely to be Choo back in the lineup on Friday.

"We'll know tomorrow," manager Ron Washington said. "I just hope he comes back. We just have to wait and see what it shows tomorrow."
