The Seattle Mariners have activated Jesus Montero off the suspended list.

Montero had to be reinstated from the suspended list with Seattle's season now complete. He put them over the limit on the 40-man roster, so they designated outfielder Corey Hart for assignment.

He was placed on the suspended list Sept. 1 after a heated confrontation with cross-checker Butch Baccala in the stands at a Minor League game.
