The 37-year-old went 3-6 with a 4.19 ERA for the White Sox in 2009 before being sidelined with a knee injury. He then spent last season training, and has had a solid winter, going 2-1, with a 1.97 ERA for Aguilas in the Dominican League. That followed a solid season in the Dominican League's regular season when he posted a 1.47 ERA over seven starts.
Desperate times call for desperate measures, and when you really only have two reliable starters you're pretty damn desperate.
