Martin, 29 next March, slumped badly over the final two months of the 2016 season but still enjoyed a nice all-around year in his debut campaign with the Mariners. Acquired from the division-rival Rangers in a trade that sent Tom Wilhelmsen to Texas (Wilhelmsen would return to Seattle after being designated for assignment mid-season by the Rangers), Martin hit .247/.306/.378 in 576 plate appearances. That slash is below the league average overall, but Martin clubbed a career-best 15 home runs despite moving to a pitcher-friendly ball park and also swiped 24 bags while making strong overall contributions on the basepaths (4.6 runs above average, per Fangraphs). His typically outstanding defense took a step back, per Ultimate Zone Rating and especially according to Defensive Runs Saved, but he was still a serviceable defender out there that comes with a strong enough reputation that a rebound in those metrics next season wouldn’t be a surprise.
The agency switch for Martin will come on the brink of his second trip through the arbitration process. The Cuban defector played the final season of his initial five-year, $15.5MM contract in 2015 but remained arbitration eligible and signed for a salary of $4.15MM. He now stands to earn a raise over that figure for the ’17 season, as MLBTR contributor Matt Swartz projects him to earn $6.3MM next year. The Mariners can control him through the 2018 season.
Martin will now join an agency that, as can be seen in MLBTR’s Agency Database, represents a large number of notable clients. Kendrys Morales, Bartolo Colon, Mark Trumbo and Edinson Volquez are among Wasserman’s free agents this offseason, and the agency also reps the likes of Giancarlo Stanton, among others. Martin’s shift is already reflected in our database, which features representation information on more than 2,500 Major League and Minor League players.
