Absolutely not. His numbers only look decent right now, because of his torrid April, with his 1.04 ERA. Since then, he has posted ERAs of 5.66 and 6.06 in May and June, plus is coming off an injury and facing a decent offense. Basically, he is total waiver garbage, and is going to pitch like his 5.05 career ERA indicates the rest of the way. I'd trade him and if you can't get value for him, drop his ASAP.
