Wells, 28, came the Mariners from Detroit as part of the Doug Fister trade. In 432 plate appearances for the M's, Wells hit .225/.304/.406 with 17 home runs. Wells is capable of playing all three outfield positions and has abused left-handed pitching to the tune of a .264/.349/.489 batting line.
The Mariners elected to go with an outfield mix of Michael Saunders, Michael Morse, Franklin Gutierrez, Raul Ibanez and Jason Bay, leaving no room for Wells on the 25-man roster. As MLB.com's Greg Johns notes (on Twitter), today was the deadline for the Mariners to make a decision regarding Wells' future.
