I have one card of Dustin Ackley, from 2011 Topps Update Set.
Playing career: Second baseman Dustin Ackley made his major league debut for the Mariners in 2011, hitting .273 with 6 HR and 36 RBI.
My memories: I remember hearing about him on the MLB Network before the season and heard about he was going to be such a big star. His first big league season was pretty pedestrian, however.
Where he is now: Slated to be the Mariners regular second baseman in 2012.
Google Autocomplete results: He is first when you type Dustin A, before Dustin Aksland, a photographer. There do not appear to be any other prominent Dustin Ackleys.
