The Orioles’ roster will be shuffling before they open the second half of the season tonight in Texas, and all signs point to left fielder Nolan Reimold heading to the 15-day disabled list. Reimold was not with the team for its workout in Texas on Thursday. And Reimold’s injury apparently has nothing to do with the lingering right hamstring injury that put him on the DL for more than seven weeks this season, but is a reoccurrence of last year’s neck pain that forced him to miss all but 16 games of a promising 2012 campaign. That’s not good news. Last year’s injury began as a herniated disk in his neck. Two epidural injections stopped the swelling, but couldn’t relieve the tingling in his left arm. Ultimately, he had season-ending surgery last June to remove the disk. Since the beginning of the 2012 season, Reimold had played in just 56 games and he hasn’t played more than 87 games in a season since his rookie year of 2009. If the injury is similar to last year’s and surgery is a possibility -- which could be the case -- Reimold’s second half is in serious jeopardy.
