J.D. Martinez’s Potential for Falling Off a Cliff
As of press time, J.D. Martinez, the biggest bat available this offseason, remains unsigned. In any normal offseason, we could chalk this up to Scott Boras slow-playing the market until he gets the deal he wants for his client. Even in this abnormally slow offseason, we probably should still chalk it up to Boras playing his normal games — although holding out until spring training, as has been reported by Jon Heyman, would represent an unusual gambit. Heyman reports that offers are currently in the $120 to $150 million range, with Boras seeking an additional $30 to $60 million on top of that upper figure. As for how much Martinez will be worth over the next five to seven years, there is a wide range of possibilities there, too.
At the beginning of the offseason, when Carson Cistulli crowdsourced deals for the top-50 free agents, respondents were underwhelmed by Martinez, seeing a five-year deal worth $110 million. Looking at projections, that seems reasonable. Generous, even. Steamer projects Martinez for a 130 wRC+ for 2018, right in line with his career average. Take away a few runs from below-average baserunning and a bunch more for subpar defense in a corner-outfield spot, and it turns into a 2.7 WAR at age 30 next season. Now 30, Martinez is more likely than not to be entering the decline phase of his career. Starting with his projected 2.7 WAR for 2018 and adjusting for age-related decline thereafter makes a $100 million contract seem almost outrageous.
Do you know what else seems a bit outrageous, though? Projecting a player with a 148 wRC+ over his last 2,143 plate appearances and a 166 wRC+ at 29 to decline so dramatically at 30 years of age. Dave Cameron believed Martinez would get a contract more representative of his recent performance, predicting six years and $156 million. Martinez is certainly a great hitter now — only Aaron Judge and Mike Trout posted higher wRC+ marks than Martinez last season — but his prospects for future production come with some uncertainty. Martinez hasn’t been a model of health in his career. As he enters his 30s, his risk for injury will only get worse.
