If you're in a redraft, you should really try to move him now. Wait a little longer and it'll become apparent to everyone in your league that he's not coming back. Sell him correctly now and someone might believe that they'll get an ace for the stretch/playoffs.
I traded him + spare parts for Pettitte a week ago. Not a great return, but I don't think he's coming back.
It's July 27th today. If he came back tomorrow, he'd need 2 weeks of long toss...that takes us to August 10th. From there he'd need 2 weeks to make 3 rehab starts...that takes us to August 24th. So best case scenario, he pitches for 5 weeks.
Let's go O's. Let's go Mets.
