Looking to ahead depth to the pitching staff, the Rangers have signed 28-year-old RHP Kyle McClellan to a minor league contract with an invitation to major league spring training.

McLellan, 28, was 12-7 as a swing man for St. Louis in 2011, starting 17 games and relieving in 26 others. He was limited, however, to just 18.2 innings in 2012 by elbow and arm problems that eventually required surgical procedures. McClellan is reportedly ahead of schedule in his recovery and is already back on a mound. He will go to camp as a starter and will be considered for both the back end of the rotation and as a long reliever, effectively making him the leading candidate to replace Scott Feldman.

"Kyle has had success on winning clubs in a variety of roles – starter, setup guy, and swing man," Rangers GM Jon Daniels said. "He'll be in the mix for any one of several spots on the staff. His versatility and makeup should be real assets to the club."

As of right now, the final spot in the Rangers' rotation likely boils down to a competition between LHP Robbie Ross, who spent his rookie season in the Rangers' bullpen and rookies LHP Martin Perez and RHP Justin Grimm. McLellan gives the Rangers a more veteran option.

A St. Louis native, McClellan made at least 60 appearances each year from 2008-10. He made 17 starts for the Cardinals in 2011, the only starts of his major league career, going 6-6 with a 4.21 ERA (49 ER/104.2 IP) in those outings. H

With the addition of McClellan, the Rangers now have 57 players on the club's spring training roster: a full 40-man roster and 17 non-roster invites.
