Losses by the Cardinals to the Pirates and the Brewers to the Cubs on Sunday clinched an NL Wild Card berth for the Diamondbacks. Their walk-off, 3-2 win over the Marlins earned them hosting rights for the Wild Card game.
The D-Backs, now 90-66, trailed the Marlins 2-1 going into the bottom of the eighth. Daniel Descalso tied the game at two apiece with an RBI single off of Brad Ziegler. Second half hero J.D. Martinez secured the win with a walk-off RBI single in the bottom of the ninth against Javy Guerra.
The Rockies beat the Padres on Sunday to increase their lead over the Brewers (+2) and Cardinals (+2.5) for the second Wild Card slot. One of these three teams will visit Arizona for the Wild Card game.
The Diamondbacks are back in the playoffs for the first time since 2011, when they lost the Division Series in five games to the Brewers.
