The Chicago Cubs agreed to terms on guaranteed split contracts with pitchers Andy Sonnanstine and Manny Corpas on Monday.

Both contracts were for the 2012 season.

Sonnanstine has spent his entire five-year career with the Tampa Bay Rays and has made 80 starts, but has been used primarily as a reliever for the past two seasons. Overall, the 28-year-old southpaw is 28-31 with a 5.26 earned run average and one save.

In 2011 Sonnanstine made 15 appearances -- four starts -- with the Rays and posted an 0-2 record with a 5.55 ERA.

Corpas missed the entire 2011 campaign while recovering from Tommy John surgery. He made 56 relief appearances in 2010, going 3-5 with a 4.62 ERA and 10 saves.
