Diamondbacks bolster offense in trade for Tigers All-Star J.D. Martinez

Updated: 

The Diamondbacks' offense has become a lot more powerful after Arizona acquired Detroit Tigers slugger J.D. Martinez.

Martinez, who will be a free agent next season, is batting .305 with 16 homers and 39 RBIs in 57 games this season.

Despite being a rental, Martinez could have extra value in the National League (NL) West with the division packed full of left-handed starters - his strength.

The Diamondbacks announced they received Martinez, 29, in exchange for infielders Dawel Lugo, Sergio Alcantara and Jose King.

Lugo, 22, played in 88 games for Double-A Jackson this season, hitting .282 with 21 doubles and 43 RBIs while Alcantara, 21, appeared in 86 games at Single-A Advanced Visalia in 2017, hitting .279 with 15 doubles and 28 RBIs.

King, 18, played in 13 games for the Rookie AZL D-backs this season, hitting .261.

The three young hitting prospects are a welcome sight for the rebuilding Tigers.

Arizona (53-39) entered Tuesday's action a half-game in front of the Colorado Rockies for the first wildcard and 5.5 ahead of the Chicago Cubs.
