Left fielder Shin-Soo Choo left Monday's game with a sprained ankle after trying to beat out an infield single in the top of the seventh inning. According to Choo, X-rays were negative, but he'll have an MRI as early as Tuesday and will likely miss at least one game and possibly more.
The Rangers already have 10 players on a disabled list that's seemed longer than a 19-inning game this season.
"I hit the bag. It felt sore so I just came out of the game," Choo said. "I don't want to make it worse."
With A's left-hander Tommy Milone starting Tuesday's game, outfielder Michael Choice was already slated to be in the lineup, and Choo might well have had the day off anyway. Now he'll definitely rest his ankle on Tuesday.
"A long season," Choo said. "I don't want to make it worse. Probably playoffs it would be a different story, but in the season we've got a long ways to go. So I don't want to make it worse."
Choo hit a leadoff home run in the first inning -- his 12th career leadoff homer and first as a Ranger -- walked in the third and had what was initially ruled to be an infield single in the ninth. But after a video review, the call was overturned, and Choo was out. Trainers taped his ankle during the break, but Choice replaced him in left field in the bottom of the seventh.
"We'll know more tomorrow," manager Ron Washington said.
