Capps has been on the disabled list with right rotator cuff irritation since July 17 and hasn't thrown since. But he's been working on strengthening his shoulder and is optimistic the MRI will come back clean.
"If all goes good, I'm going to start playing catch on Wednesday," Capps said. "Then, from my understanding, every other day for a week, then every day, then off a mound."
Capps added there's no timetable for his return, but that he hopes to be back by early September.
"Barring something drastic or something new, I've got full intentions of pitching in September," Capps said. "Sometime early September I anticipate being back out there. I haven't seen a hard schedule or anything like that, so it's hard for me to say Aug. 30 or Sept. 5 or anything like that. Just early September is when I'm hoping to be back out there."
