Cubs purchased the contracts of LHP Will Ohman and LHP John Koronka from Triple-A Iowa.
A couple of borderline choices here. Ohman, who was on the 40-man roster before missing 2003 after undergoing Tommy John surgery, had a 4.30 ERA as a reliever for Iowa this season. Maybe he can still make it as a lefty specialist. Koronka is less likely to have any real impact in Chicago. He had a solid season for Iowa, going 12-9 with a 4.34 ERA, but the Cubs have a bunch of better pitching prospects.
