Mariners top prospect Dustin Ackley will make his big league debut tomorrow against the Phillies. The second baseman has a .303/.421/.487 line at Triple-A this year. He was the second overall pick in the 2009 draft.
No 40-man roster move was necessary; Luis Rodriguez was optioned to open a spot on the 25-man. It appears that Ackley will accrue a maximum of 104 days of service this year, so he's unlikely to qualify as a Super Two player after the 2013 season should the criteria remain the same. He'll be arbitration eligible after the 2014 season and under team control through 2017.
The Ackley call-up prompts the Seattle Times' Geoff Baker to think about the possibility of trading infielder Jack Wilson. Baker thinks the team may keep the veteran, as the current focus is the pennant race.
