OAKLAND -- Just when the A's outfield appeared to be nearing a return to full health, Oakland manager Bob Melvin announced on Sunday that starting right fielder Stephen Piscotty had aggravated his sprained right ankle and had to undergo an MRI.

Piscotty initially sprained the ankle last Saturday on an awkward slide back into second base on a pickoff attempt. He has played through the ailment since then but was seen in a walking boot Sunday morning.

"It got a little better, a little worse, and then last night he took a swing where it really bothered him," Melvin said. "He had an MRI this morning. We're waiting on the results of that. I don't have a great feeling about it at this point, but we'll see what the doctors have to say and then proceed accordingly."

Piscotty, 28, missed all of July with a sprained right knee but returned from the injured list in early August. Unfortunately, center fielder Ramón Laureano then went on the IL with a stress reaction in his right shin. Now with Laureano nearing a return, it appears Piscotty might miss some time again.

The good news for the A's is that they have plenty of outfield depth. Mark Canha filled in for Piscotty when he was out with the knee sprain and figures to take over right field again when Laureano returns to center. Robbie Grossman and Chad Pinder should continue to split time in left.

Piscotty is slashing .252/.312/.416 with 13 home runs and 44 RBI in 92 games this year. He's in the third season of his six-year, $33.5 million contract, originally signed with the St. Louis Cardinals.
