Capuano is more of an insurance policy than anything else. I don't think he has what it takes to start in the AL though, especially not the AL East. He's not the type of pitcher that will miss many bats for sure. He's allowed a little over a hit per inning in his career, and even more last year. His K rate is also slipping. That being said, he isn't meant to really be someone they depend on unless they have injury issues, which is always possible with Buchholz and Peavy in the rotation.
Slightly below average pitcher. Coasted the Dodgers .6 of a win Almost granted to give up a long ball per game. Has good control, a pretty solid FIP and xFIP compared to his 4.26 E.R.A.
The pick up could go either way. He could be a good pick up and pitch fairly well, or just bust.
