He's homer prone? In 2007 he gave up a total of 4 HRs in 63 innings. Last year he gave up 6 in 70 innings. If his 2007 IP was tripled (i.e. to that of a good starter), he would have been on pace to give 12 homers. Double his 2008 IP, and he also tracks for 12. This year he has yet to surrender one. Does that really classify as homer prone?
Bottom line, he does the job.
