Clay Buchholz 16 starts, 7 wins, 92 IP
Daisuke Matsuzaka 12 starts, 4 wins, 59.1 IP
Both Buchholz and Matsuzaka had their ups and downs in 2009. Both pitchers might be top three starters on any other team, but it's probable that Matsuzaka will be the fourth starter, and Buchholz the fifth. Both have a high upside, but both also have a lot to prove.
