ARLINGTON - Outfielder Shin-Soo Choo, racing the clock, had seven plate appearances with the Rangers' instructional league team for the second consecutive day on Tuesday.Choo is on the disabled list for the fourth time this season. He has not played since Aug. 15 because of fractured left forearm but is trying to make it back for the post-season.The Rangers likely will activate Choo on Friday and play him in the final three regular-season games to determine if he should be on the roster for an American League Division Series.There are two steps to the process, manager Jeff Banister said.
