Shortly before tonight’s game against the Royals in Kansas City, the Detroit Tigers traded right fielder J.D. Martinez to the Arizona Diamondbacks in exchange for three infield prospects: Dawel Lugo, Sergio Alcantara, and Jose King.
As he has in every season since he joined the Tigers and reconstructed his swing, Martinez has been among the best hitters in baseball in 2017. If he had enough plate appearances to qualify, he would be the fifth best hitter in baseball by wRC+ (162) to this point in the current season. He doesn’t yet have enough plate appearances to qualify, though, because he again missed time due to injury this year, and his defensive contributions continue to oscillate between positive and negative. He’s also a rental, with free agency and a significant payday headed his direction this offseason.
That last part is the reason the Tigers had to trade Martinez this month. In the combined absence of an ability to resign him on the open market and of a currently competitive team, they had to cash out whatever value they could now. Still, most Detroit fans are reacting to this trade with extreme disappointment, and national observers are calling the Tigers’ return for Martinez “very light.”
Yes, Martinez likely is going to crush left-handed pitching in the NL West and see his power numbers soar even higher in the thin desert air, but he’s still a rental with an inky injury report. Tigers fans understandably came to love Martinez, but their apparent hopes that his always inevitable trade would return a prospect haul the likes of which the White Sox just secured from their crosstown rival in exchange for Jose Quintana are not reasonable. Since 2014, Martinez has been worth 9.2 WARP and Quintana has been worth 12.7 WARP. (Simply for context, Miguel Cabrera contributed 14.5 WARP over that period.) The new Cubs pitcher also is over a year younger than Martinez and has team-friendly years remaining on his contract. It makes sense that trading Quintana would net the White Sox a package including one of the sport’s overall top prospects. Ten weeks of Martinez simply pales in comparison.
The Tigers’ trade has generated plenty of criticism of the team’s first-year general manager, Al Avila. I am not a prospect scout, but, from the perspective of the team’s fan base, I think much of this criticism is, at a minimum, premature. Avila has many years of experience as an assistant general manager under Dave Dombrowski and is well-regarded as a talent evaluator. He is entitled to the same benefit of the doubt fans accorded Dombrowski, whose transactions were regarded with assumed confidence and assessed together, rather than individually.
For Detroit, the 2006-2016 run is over and the proverbial window is closed. The next two weeks are of critical importance to this team’s future. Maybe they stumbled out of the gate with tonight’s trade, but there are more moves to be made. Keep an eye on Justin Wilson, Alex Avila, and even Justin Verlander. Painful as it feels, this, for better and worse, is how a new age of Detroit baseball begins.
