Via ESPN, there’s a list of pitchers who are known to have terrible first innings. Our own Daisuke Matsuzaka is right there (7.56 ERA), fourth on the list behind others like Kevin Millwood (11.03), Chris Narveson (9.32) and Johan Santana(7.76). Hmm. I was all prepared to say something nasty about these guys, but then Santana’s name is in there. Of course, this is just 2010 data, so we’re not talking about a whole lot of starts here.
I’ve noticed before that Daisuke seems to be slow in getting into a groove, so I wanted to expand this to his MLB career to see if it was more generally true. Here’s the data:
Clearly 2010 was a particularly bad year for Matsuzaka. But we can take his career 5.23 ERA in first innings and compare it to his overall ERA, which is 4.18 and say that he does seem to have trouble first innings. The 65% clean inning rate doesn’t seem terribly out of line with what is expected statistically for an average pitcher. Combine those two things, and we can conclude that Dice-K struggles with big first innings (moreso recently).
Playing catchup is no fun for anyone, and that’s probably why people have such a bad impression of Matsuzaka as a pitcher, even though his ERA is actually better than Josh Beckett’s career ERA of 4.28 as a Red Sox. In addition to staying healthy, Matsuzaka needs to prepare for games better, and then he just might be a good pitcher again.
