Solid? Maybe. The first two, Rogers and Bonderman have done great so far. Maroth and Robertson are questionable. I can see the spark in them, but they were so inconsistent last year. One game would be good, the next not so good. As for Verlander, I still haven't made a judgement. He's young. Let's see what he's done by the All Star Break and I can tell you how good he'll be.
Even though, his first game pitching, will be a game that you don't want a miss. It'll be exciting with him out there. I'm sure he'll be nervous though.
