Rangers sign veteran left-hander Saunders

Addition expected to provide depth to starting rotation in Texas

Rangers sign veteran left-hander Saunders

The Rangers signed left-hander Joe Saunders to a Major League contract on Wednesday.

Infielder-outfielder Alex Castellanos was designated for assignment to make room for Saunders on the big league roster.

The nine-year veteran spent last season with the Mariners, posting an 11-16 record and a 5.26 ERA in 32 starts. The Mariners declined their 2014 option on Saunders' contract after the season.

Saunders, an All-Star in 2008 with the Angels, has pitched for three teams -- the D-backs, Orioles and Mariners -- over the past two seasons. He is 89-81 with a 4.30 ERA in his career.

A report on Tuesday said that Saunders worked out for the Rangers last week in Surprise, Ariz., and the lefty told MLB Network Radio that Texas would be a "perfect fit." Saunders adds depth to a starting rotation that may not have Derek Holland and Matt Harrison at the beginning of the year because of injuries.
