I think Johan will be fine, as he's not done badly at all this year. However, people expecting him to repeat his 2nd half from last year doesn't make sense. Planning for a player to have an ERA around 1.20 and a Whip of .75 for the 2nd half probably isn't wise. I'm sure that ERA will come down though K's will be there, and he'll probably win 17-18 on the year.
...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
