When it comes to making moves for pending free agents at the trade deadline, it’s hard to say that any pure rental is going to be a bargain. In recent seasons, the most successful trade for a soon-to-be free agent is probably the New York Mets’ acquisition of Yoenis Cespedes from the Detroit Tigers two years ago. Cespedes caught fire over the last two months of the season, putting up a 156 wRC+ and helping the Mets to the World Series. The cost was steep, however: part of Detroit’s return, Michael Fulmer, came in at 22 on Dave Cameron’s Trade Value Series this year.
If there’s a Yoenis Cespedes-type player available this year, it’s the guy whom the Arizona Diamondbacks just acquired. And they don’t appear to have conceded any top prospects for him, either, with Detroit opting for some players further away from the majors, potentially indicating where their future is headed.
Here’s the deal in full:
Arizona gets
Detroit gets
Arizona is win-now mode. Also, they don’t have a great farm system, and Daniel Descalso has been their regular left fielder of late. Even if the injured Yasmany Tomas returns, he’s still just a replacement-level player. J.D. Martinez, meanwhile, provides at least a one-win upgrade over the course of the rest of the season.
Nor does the price appear to have been particularly high. The Diamondbacks retain top prospect Anthony Banda. As for the players they dealt, Lugo was the Diamondbacks’ 10th-best prospect coming into the season. The 22-year-old second baseman has some power and is holding his own in Double-A. Alcantara is a strong-armed shortstop putting up an average line in High-A, while King is an 18-year-old infielder getting his first exposure in the US in Rookie-level ball in Arizona. Detroit seems to have opted for some lottery tickets in exchange for potentially the best hitter on the market.
You might be forgiven for not totally believing in J.D. Martinez. His career got off to a poor start, and of late, he can’t seem to stay healthy. You might even be forgiven for thinking that Martinez is an aging slugger in decline. He’s not that, though. Teammate Victor Martinez fits that bill, and J.D. certainly has the old-man skillset of power and walks while offering little on defense. J.D. Martinez is just 29 years old, though, and since he joined the Tigers in 2014, he has been one of the very best hitters in baseball.
A champion of the fly-ball revolution, Martinez has put up a 146 wRC+ since joining Detroit, which is ninth in baseball over that span, just behind Nelson Cruz, tied with Anthony Rizzo, and ahead of Josh Donaldson, Giancarlo Stanton, and Justin Turner.
Martinez isn’t relying on 2014 and 2015 to prop up his stats, either. Since the beginning of last season, his 148 wRC+ trails only Mike Trout, Freddie Freeman, Joey Votto, Jose Altuve, and Daniel Murphy. This season, Martinez has been even better, hitting .305/.388/.630 with a 162 wRC+. It’s possible the season has flown a little under the radar, as his name is absent from the leaderboards. That’s only because Martinez missed the first month of the season with a sprained ligament in his right foot, however. As a result, he’s accumulated just 232 plate appearances, not enough to qualify for the batting title. If Martinez had hit 16 homers with a 162 wRC+ in April and May instead of May and June, he probably would have made the All-Star team. He didn’t, and while we are mostly talking about past performance, his projections look great, as well.
