Well let's not go comparing Danny Haren to Rich Harden just because they put up similar crappy stats in a half season. Anyway, Haren's been nice, and yes if your staff isn't that strong use him to play the match-ups. Don't forget he is very young though, and this will be his first real season in the majors. He's thrown over 100 innings so far, and may very well tire. Also, incosistency will be a problem.. just a warning.
Maybe a good time to try and deal this kid if you can..
...Boston papers now and then suffer a sharp flurry of arithmetic on this score; indeed, for Williams to have distributed all his hits so they did nobody else any good would constitute a feat of placement unparalleled in the annals of selfishness. -Updike
