CLEVELAND -- It's unclear what type of additions the A's will make come Sept. 1, when rosters officially expand, but the club could be getting back a familiar face around the same time.
Michael Wuertz (thumb) tossed a scoreless inning for Class A Stockton on Sunday, allowing a leadoff hit before retiring the side on strikeouts. He could potentially need only one more rehab appearance before returning to the club. Wuertz has been stationed on the 15-day disabled list since July 30.
"His velocity was up to 93, and he felt really good from the comments I read on the report," manager Bob Melvin said. "I can see him making at least one more start."
The A's have used a handful of other arms in the seventh inning in Wuertz's absence, most notably Fautino De Los Santos, who has a 4.82 ERA over his last 11 games in increasingly significant roles after posting a 2.35 mark in his first 12 contests.
