BALTIMORE -- Left-hander Sean Doolittle will make one or two more rehab appearances before rejoining the A's, who are expecting their closer back sometime on their next road trip that begins Aug. 24 in Seattle.
Doolittle struck out the side in a 13-pitch inning for Triple-A Nashville on Sunday, marking his fourth Minor League rehab outing since going back on the disabled list in May with a strained left shoulder.
"It's the best he's felt," A's manager Bob Melvin said. "Each and every time he's said that, so he's getting more and more comfortable."
Doolittle, to this point limited to just one inning of work this season after saving 22 games in an All-Star 2014 campaign, has struck out seven in a combined four innings for the Sounds since beginning his rehab assignment Aug.
