(CBS) The Cubs agreed to terms with two right-handed pitchers Monday on non-guaranteed split contracts for next season.

Andy Sonnanstine and Manny Corpas both signed with the club Monday with their eyes on joining the pitching staff in 2012.

Sonnanstine, 28, spent the last five seasons with the Rays and was used as both a starter and a reliever in Tampa. He broke out with the club as a starter in 2007, going 13-9 with a 4.38 ERA in 32 starts. He has been used primarily as a reliever the last two seasons.  Overall, the right-hander is 28-31 with one save and a 5.26 ERA in his major-league career.

Sonnanstine spent some time in Triple-A last season and will look for a fresh start with the Cubs.

Corpas, 29, is a relief pitcher who spent five seasons with the Rockies before missing the 2011 campaign because of Tommy John surgery. He is 12-16 with 34 saves, 51 holds and a 3.93 ERA in his career.
