The Mariners have signed second overall pick Danny Hultzen, according to Larry Stone of the Seattle Times (on Twitter). It's a five-year deal worth at least $8.5MM and up to $10.6MM, according to Geoff Baker of the Seattle Times (on Twitter). The contract includes a $6.35MM bonus, according to Stone. CAA represents the left-hander.
