His career record of 34-19 is deceiving. He's got a career ERA of 4.02 and a WHIP of almost 1.400. His 18-3 record last season was largely fool's gold (I can't believe I just quoted the nasally know-it-all himself, Jason Page). He was propped up a ton by the bullpen last season and got out of a lot of seemingly inescapable jams. Living on the edge like he has is catching up with him in a major way.
I wonder how long it's going to take for Matsuzaka's contract to be on that list of worst free agent signings ever. I can see it up there along side Kevin Brown, Barry Zito, and Mike Hampton.
