The fact that Doubront has no options really ties their hands. They can't send him back or some team is likely to claim him. His command at the beginning of games is so poor that he can't be trusted to be a reliable bullpen piece. IMO, he has the inside track on the rotation spot, but he has to improve his command. I would have been less discouraged yesterday if he had trouble with his command in the early innings but was able to gather himself and work out of the jams. That is not what happened. He avoided big damage with a lucky strike'em out throw'em out double play as the result of batter's interference. In his entire outing he didn't look sharp -- not even for 1 inning.
Melancon was very very disappointing. I am not basing this on the result of this appearance. I am basing this purely on his stuff. It is nothing special... period. His stuff is not intimidating, not does he have an intimidating presence on the mound. The step down in caliber from Bard is enormous. Get ready for lots of heart attacks in the late innings. Lots of them.
