CC is an Ace. There's probably like 7 ace type pitchers in baseball, Lee, CC, Halladay, Verlander, Kershaw, Lincecum and maybe Felix. Not in that order either. Lester is a #1 but I wouldn't call him an ace. CC has the advantage over Lester, this year anyway. I think Lester starts maturing a bit more and CC will start to decline in years to come. Still a close call though.
I will say Beckett is better than Pineda but I think the difference there washes away the difference between CC and Lester. I just think both have down years from their 2011 seasons.
Nova and Buchholz is pretty close too... I think I should of put Kuroda here but I like this match better cause they're around the same age. Both had good stuff, Buchholz has better stuff but Nova's the better pitcher if that makes sense. I'd give the advantage to Buchholz though.
Kurado vs Bard, not close....
Hughes/Garcia/AJ vs Aceves/Padilla/Cook/Miller. If you take the worst Yankee starter here, AJ and the best red sox have to offer here... Aceves I think the Yankees will take it. Cause AJ will give you 200 innings and Aceves pitched 110 inning last year, so even if he's really good, you might not see him over 150 innings.
