Mariners shortstop Colt Emerson will undergo season-ending surgery on his left wrist, per MLB Trade Rumors. Emerson is already on the 10-day injured list and is expected to be healthy by next spring training, according to reporting from The Seattle Times.
Emerson, the Mariners' No. 1 prospect, signed an eight-year, $95 million contract before being promoted to the majors, per Yahoo Sports. The injury marks a difficult end to what has been described as a tough debut season for the young shortstop.
