CBS Sports' Jon Heyman reports that the Yankees, Mets and Padres have asked the Mariners about the availability of Dustin Ackley. No word on whether the Mariners actually plan to move him. Ackley owns an underwhelming .245/.315/.354 batting line over his first three seasons in the majors, but he was highly-regarded for his hitting ability coming out of college and doesn't turn 26 until January. The Mariners used him as an outfielder during the second half of the season, but there's a chance he could be moved back to second base if he is traded elsewhere.
