Considering the article says he isn’t ready and will be in Arizona building up strength, your totals are probably a best case scenario. I’d expect he finishes with about half of those numbers, or less (2-3 starts, 10-20 IP)
He might not even see the parent club in August, just like he wouldn’t had Bloom been the GM to sign him. Given the terms of his contract, the Dodgers clearly expect very little out of him.
Of all the pitchers to complain about missing out on, Hamels should probably be last on the list. The Sox would have been better off outbidding the Cardinals for JA Happ or Jon Lester…
