The Mariners announced that they have released Jack Cust, who was designated for assignment last week. Seattle's 40-man roster now has 39 players and the Mariners have an empty 25-man roster spot after optioning Greg Halman to Triple-A.
Cust, 32, posted a .213/.344/.329 line with three homers in 270 plate appearances this year. After averaging 28 homers and 103 walks with the A's from 2007-09, Cust's power numbers have fallen off. The left-handed hitter signed a $2.5MM deal with Seattle in December after the A's non-tendered him.
