Worth noting

• Catcher John Jaso (concussion) is scheduled to have more tests Saturday, when the A's hope to have a better idea of how close he is to returning to baseball activities.

Jaso was eligible to come off the seven-day concussion disabled list Thursday.

"I know he's feeling better every day," Melvin said, "so that's a good sign."

• Josh Reddick, held out of Wednesday's game after sustaining a head injury in a three-player collision the night before, had a series of tests Friday afternoon and was subsequently cleared to return to the lineup for Oakland's series opener against Texas.

• Though Melvin planned on keeping his rotation as is through Monday and Thursday's off-days, he did mention Friday that "things could change based on performance in the coming days."

"We'll see," he said. "As I sit here right now, we'd probably look to give these guys the extra rest, and I think this is the perfect time in the season to do it."
