The Rangers have designated right-hander Seth Rosin for assignment and purchased the contract of third baseman Kevin Kouzmanoff, reports Evan Grant of the Dallas Morning News (on Twitter).
Texas has a need at third base following a quad injury to Adrian Beltre in yesterday's game. Kouzmanoff, a veteran of six Major League seasons, can fill that role should Beltre need to miss time, though he hasn't appeared in the Majors since splitting the 2011 season between the A's and Rockies. Kouzmanoff, 32, blasted at least 16 homers and 30 doubles in each season from 2007-10 with the Padres and A's but also struggled to get on base in that time (combined .303 OBP). He's a career .255/.300/.420 hitter that has spent the past few seasons in Triple-A with the Royals and Marlins.
Rosin, 25, was the Mets' selection in last December's Rule 5 Draft (from the Phillies). He was immediately traded to the Dodgers for cash before being claimed off waivers by Texas in late March. Rosin made his big league debut with the Rangers this season, allowing three runs on six hits and a walk with three strikeouts in four innings of work. The former fourth-round pick has a 4.00 career ERA in the minor leagues to go along with solid ratios of 8.3 K/9 and 2.7 BB/9. Prior to his selection in the Rule 5 Draft, Rosin had never appeared in a game above the Double-A level.
