Earlier this week, the Mariners and Rays made the offseason’s first major trade, a five-player swap in which catcher Mike Zunino and outfielder Mallex Smith changed teams. That may prove to be the first of multiple noteworthy deals Mariners trade-happy GM Jerry Dipoto orchestrates this winter, especially considering his intention to “re-imagine” his team’s roster. The majority of that roster is available for trade, Jon Heyman of Fancred reported prior to the Zunino deal, though he added that outfielder Mitch Haniger, closer Edwin Diaz and left-handed Marco Gonzales appear safe.
The most interesting name missing from Heyman’s list is Gonzalez’s fellow southpaw starter James Paxton, who’s Seattle’s closest thing to an ace. With the 30-year-old Paxton down to his final two seasons of team control, Ryan Divish of the Seattle Times has heard that the Mariners will trade him this winter.
While Paxton does have a checkered injury history and has only exceeded 160 innings in a year once (last season, when he tallied 160 1/3), the fireballer is still one of the majors’ premier lefties. Paxton has averaged just 24 starts and 139 innings a season since 2016, his breakout campaign, but the Big Maple nonetheless racked up 11.9 fWAR during that three-year span. In that regard, only 12 starters bettered Paxton, who’s sandwiched between Noah Syndergaard and Luis Severino. And since 2017, Paxton ranks fourth among starters in K/9 (11.06), fifth in FIP (2.95), 11th in K/BB ratio (4.61) and tied for 21st in ERA (3.40).
Paxton’s projected to earn $9MM in 2019, a far lighter commitment than the best free-agent starters will rake in this winter, which only adds to his appeal. Acquiring Paxton would still sting a team to a degree, of course, as that club would presumably need to part with a big-time haul to land him. In shipping Paxton out, perhaps Seattle would significantly boost a farm system which has long languished at the bottom of the majors.
Here’s a look at potential suitors for Paxton, going from best to worst record in 2018:
