Rangers' Preston Claiborne: Promoted to major leagues

Claiborne was called up from Triple-A Round Rock on Thursday.

The right-hander will get his first major-league opportunity in nearly three years, replacing Jeremy Jeffress (back) in the Rangers' bullpen. Claiborne has served as the closer with Round Rock throughout the season, notching 13 saves while pitching to a 1.37 ERA and 1.29 WHIP, but he will likely work mostly in the middle innings with Texas.
