Big start for Homer

Is tonight's game a big start for Homer Bailey?
"Yeah, it's a big start for Homer,"said Reds manager Dusty Baker. "It's not do or die, but it could sure help his cause a lot."
Baker didn't say as much, but some other things would probably have to happen for Bailey to win a spot in the rotation. Something like a sore arm for either Johnny Cueto, Edinson Volquez or Josh Fogg.
Much has been made this spring of wanting to make sure prospects are ready when called to the big leagues. It's the company line on center fielder Jay Bruce, for example.
If "readiness" were the measuring stick last year, there is no way Bailey would have been called up. The Reds needed a healing moment last summer, to reconnect the alienated fan base to the faltering team, and Bailey provided it.
But the call-up ran totally counter to what has been expressed by the brass this spring.
