Nick Blackburn had a career 2.0 BB9, 5.4 SO9, and 3.65 ERA in the minors. 3.5 BB9, 6.4 SO9, and 3.38 ERA for Stewart. That's an awful lot of walks for someone who doesn't strike people out. Stewarts success in mlb came agains bad teams. Overall production wasn't great. He's going to have to develop a swing and miss pitch and/or significantly improve his control to have any kind of career in MLB. It would be nice to see this happen, but I wouldn't bet on it.
