Line score

Gray was rocked early, allowing two singles to start the bottom of the first, followed by a three-run home run to Paul Goldschmidt. Gray was ultimately knocked out of the game in the bottom of the second after David Peralta singled and scored on Ketel Marte's triple. Daniel Descalso's two-run home run off Tyler Anderson in the third made it 6–0 Diamondbacks. While Greinke coasted through the first three innings, he was unable to complete the fourth inning. After allowing two singles and recording one out, Gerardo Parra's single, Mark Reynolds's groundout, Jonathan Lucroy's double, and Alexi Amarista's pinch hit single scored a run each and reduced the Diamondback's lead to 6–4.^[4] This lead was cut further to 6–5 in the seventh when Lucroy doubled, moved to third on Robbie Ray's wild pitch and scored on Charlie Blackmon's bunt groundout off Jorge De La Rosa, but the Diamondbacks extended their lead to 8–5 in the bottom of the inning on Archie Bradley's two-run triple off Pat Neshek. In the process, Bradley not only became the first relief pitcher to record a triple in a playoff game, but also the sixth pitcher in Major League history to record a triple during the playoffs.^[5]

Back-to-back home runs by Nolan Arenado and Trevor Story off Bradley in the eighth cut the Diamondbacks' lead back to one. The Diamondbacks responded in the bottom half of the inning with A.J. Pollock's two-run triple off Greg Holland (which made the Diamondbacks the first team since the Boston Americans in 1903 to record four triples in a playoff game). After an intentional walk, Jeff Mathis's RBI squeeze single made it 11–7 Diamondbacks. In the ninth, Ian Desmond hit a leadoff single off Fernando Rodney, who struck out the next two batters, but Desmond advanced two bases on defensive indifferences before scoring on Carlos González's single to cut the Rockies' deficit to 11–8. Arenado then grounded out to end the game as the Diamondbacks advanced to the NLDS.
