• Alberto Callaspo, who exited Wednesday's game in Cincinnati with a left forearm contusion, was deemed good to go with no limitations on Friday, though he wasn't in the starting lineup. He entered in the ninth as a defensive replacement.
• A's lefty Brett Anderson (right foot) will pitch in simulated games on Saturday and Tuesday, and there's no telling yet if a rehab start would be next -- or if he'll even need one, since he'll already have built his pitch count to around 80.
"Depending on how things go in between, we'll probably keep our options open," Melvin said, "but you always do want to get him in game action, real games other than simulated games."
• Catcher John Jaso (concussion) continues to improve, but, according to Melvin, "not to the point where they're comfortable having him do baseball activities."
Jaso had a .415 on-base percentage in the 16 games before he was placed on the seven-day disabled list on July 25.
"He's obviously a guy we rely on, and hit high up in the order for us and got on base and had some key hits for us, and every now and then hit one out of the ballpark," Melvin said. "He's a guy we expected to be a major contributor offensively, and we do miss him. Losing him has hurt some."
