Tolleson, Rosin finish out bullpen

SAN ANTONIO -- The Rangers have completed their Opening Day bullpen by adding right-handers Shawn Tolleson and Seth Rosin. Tolleson gives the Rangers another right-handed setup reliever and Rosin will serve as the long man.

Tolleson was claimed off waivers from the Dodgers and had a 2.25 ERA in the Cactus League, plus two scoreless against the Quintana Roo Tigers on Thursday night. He was 3-1 with a 4.30 ERA in 40 games for the Dodgers in 2012 before missing most of the 2013 season with a herniated disk in his lower back.

Rosin is a Rule 5 Draft pick claimed on waivers last Wednesday from the Dodgers. He has to stay on the Major League roster for the whole year or be offered back to his original team, the Phillies, for $25,000. He pitched a scoreless inning against the Astros on Saturday and two against the Quinana Roo Tigers on Thursday.

"We're still watching him," manager Ron Washington said. "He's getting outs. He's showing a good slider and keeping the ball down in the zone. We're hoping he can continue to get outs."

The Rangers have sent pitchers Ryan Feierabend, Daniel McCutchen and Justin Germano to Triple-A Round Rock. Colby Lewis has also been officially assigned to Round Rock.
