Cowgill, who's eligible to come off the 15-day disabled list on Sunday, has been out with a sprained left ankle, but he said on Saturday that he's not feeling any pain at this point. The biggest test has been running the bases, since rounding the bags puts extensive pressure on the injured ankle.
Barring any setbacks, Cowgill will do more game-like activities on Sunday and then go from there.
"See how that goes," Cowgill said. "If I pass that test, it'll be up to them to figure out the next step. Hopefully they'll be telling me to play somewhere [on a rehab assignment]."
A's manager Bob Melvin didn't have an exact date for when Cowgill could begin said assignment with a Minor League team, but Melvin did say that the outfielder is probably three or four days away from doing so.
"We want to make sure once he starts a rehab assignment that he's doing everything as close to 100 percent," Melvin said. "Again, it's tough to simulate getting out of the box, doing some of the things you have to do in a game, but we feel like he's getting a lot closer."
