1. He left Saturday's game, so if he doesn't pitch until Tuesday at the earliest, that would be 9 days until Tuesday, June 18th.
2. By putting him on the DL, he would only miss one potential start if he's ready to go on the16th day.
3. Given how he keeps getting pushed back (from tomorrow, to Sunday to now Tuesday at earliest), the chances of him pitching on Tuesday are not 100%.
DL him already and get the extra pitcher up here (Wilson for example).
Until he gets back, get by with Lackey, Doubront, Dempster, Lester, Morales, Aceves (Tuesday doubleheader call up).
