The Rangers acquired Gearrin, Austin Jackson and minor-leaguer Jason Bahr from the Giants on Sunday, Henry Schulman of the San Francisco Chronicle reports.
Gearrin had a 4.20 ERA and 1.53 WHIP over 30 innings with the Giants this season, but hasn't allowed a run in his last six appearances. The 32-year-old seems slated for a middle-relief role out of the Rangers' bullpen, but he could work toward a higher-leverage role if the team offloads any of its back-end pieces for prospects.
