ANAHEIM -- The A's remain hopeful they can avoid adding another member of their starting staff to the disabled list, with lefty Sean Manaea reporting progress a day after exiting his start in Anaheim with left shoulder tightness.
Manaea didn't pick up a baseball Thursday, but will test his shoulder in Houston on Friday by playing catch. Only then will the A's have a better idea how long they'll be without him.
"It feels better than it did yesterday," Manaea said. "We'll see how tomorrow goes and then go from there."
Manaea made it through just two innings and 34 pitches Wednesday night, showcasing diminished velocity in the three-run outing.
