Anticipated for the Wild Card Game is a matchup of the teams' top pitchers -- Arizona right-hander Zack Greinke (17-7, 3.20 ERA), who was announced Saturday by manager Torey Lovullo, against Rockies righty Jon Gray (10-4, 3.67).
The D-backs will have home field after earning the top Wild Card and finishing second in the NL West. The Rockies finished third and outdistanced the Brewers for the second Wild Card. Game time Wednesday is 6:08 p.m. MT. The game will be telecast on TBS.
The winner will meet the Dodgers on Friday to open the best-of-five NL Division Series presented by T-Mobile.
In five starts this season against the Rockies, Greinke is 2-1 with a 3.41 ERA. The Rockies have won two of the three meetings vs. Greinke at Chase Field, with Greinke getting the winning decision in a 6-2 triumph July 1 and not figuring in the decision in the two losses -- 7-6 on April 29 and 5-4 on Sept. 11.
Gray is 2-1 with a 3.50 ERA in three starts against the D-backs this season. The loss occurred at Coors Field on Sept. 2, when Gray gave up three runs and five hits in five innings. Gray is 2-0, 2.77 at Chase Field this season. On June 30, his first game back from missing a month and a half with a navicular stress fracture of the right foot, he went six innings and gave up two runs on seven hits. On Sept. 12, Gray held the D-backs to seven hits and two runs in seven innings. He struck out 10 in each win and has fanned 26 D-backs total.
Greinke is 3-3 with a 3.55 ERA in nine postseason starts with the Brewers (2011) and Dodgers (2013-15). Gray, the Rockies' top Draft pick in 2013 and a rookie last season, will be making his first postseason appearance.
The D-backs won the regular-season series, 11-8. Interestingly, the only teams to defeat the Dodgers in the season series this year were the D-backs (11-8) and the Rockies (10-7 going into Saturday).
It'll also be a return to the postseason for Rockies outfielder Carlos Gonzalez, the only player who was part of the team's last trip to the postseason in 2009 -- when Colorado lost in four games to the Phillies in the NLDS. Gonzalez went 10-for-17 (.588) with a homer, two doubles, an RBI, two walks and a strikeout in that one.
