Well, you asked for the conservative estimate. He could move up quicker than that, but I think it's tough to envision him being a possibility for the Major League club before 2011. He's not a college pitcher with a lot of high level instruction and experience, he needs time to refine his repertoir. For comparison, Zambrano pitched in Low A in 1999, and aside from a September callup, he wasn't a factor in the Majors til 2002. Jae-Kuk Ryu spent part of 2002 and most of 2003 in Lansing, but didn't hit Iowa until 2006(although he had a 30 IP season, due to injury I believe).
