During May, he made 6 starts. HE gave up more than 3 earned in only one start. One of those starts, he gave up and unearned run, so 4 if you don't think 3 earned over 6 IP is OK. 4 of the starts, he went 6, the 5 IP start, he only gave up 1 run, and the 5.2 IP start, he gave up 2 runs. Still ended up with 4.93 ERA and an atrocious K%.
I get we should be done with him and that he's not getting the Ks we want, but if he can limit his bad starts to 1 per month, that's adequate.
