The Chicago Cubs have signed right-handed pitchers Andy Sonnanstine and Manuel Corpas (reported last week) to non-guaranteed split contracts for the 2012 season, the club announced via Twitter.

Twitter / @CubsInisder - The #Cubs have agreed to terms with RHP Manny Corpas and LHP Andy Sonnanstine on non-guaranteed split contracts for the 2012 season.

The Manny Corpas signing was believed to be a major-league deal, but it will be a non-guaranteed split contract. Corpas, coming off Tommy John surgery, will look to pitch in the majors for the first time since 2010. Corpas turned down a major-league deal from the Texas Rangers, according to reports.

Meanwhile, I can't imagine anyone offered Andy Sonnanstine a major-league deal. The 28-year-old was dreadful for the Tampa Bay Rays last season; posting a 5.55 ERA across 35 2/3 innings of work with a 1.00 strikeout-to-walk ratio as the team's long-man. I can't imagine him turning it around, but it's not going to be expensive for the Cubs to find out.
