So Moehler has a schedule for his rehab starts:
Monday: Throw bullpen session in Houston
Monday night: 60-pitch start in Round Rock (which should get him 2-3 innings).
Tuesday: Rejoin Astros in Philadelphia
Next Sunday: Throw rehab start in San Antonio for Corpus
The rosters expand to 40 a week from this coming Wednesday, so if everything goes well, he will likely be added then.
