The Mariners didn't wait long to bring back Hisashi Iwakuma after his agreement with the Los Angeles Dodgers failed to get finalized. Iwakuma agreed to a $12 million, one-year contract with Seattle late Thursday night, a deal that includes options for the 2017 and 2018 seasons and performance bonuses that could raise the value to $47.5 million over three years if he pitches at least 190 innings per season. The team posted a video on Twitter of general manager Jerry Dipoto announcing the signing at the club's holiday party.
