The Diamondbacks might look back in a month or so and declare this their biggest game of the year the one they had to win and if they do the script that was followed on Tuesday night couldn’t have been more fitting.

Paul Goldschmidt and Patrick Corbin the two players most responsible for their team being anywhere near the playoff race delivered yet again Goldschmidt hammering a grand slam and Corbin dominating in complete-game fashion and the Diamondbacks beat the Cincinnati Reds 5-2 to climb within five games of the wild card.

Goldschmidt connected for his 31st home run a line drive over the left-field fence that brought his RBI total to an even 100 while Corbin tied a career-high with 10 strikeouts and did not walk a batter in throwing his second complete game.

“Those two guys have been huge” Diamondbacks catcher Wil Nieves said. “I’m pretty sure that before the season started they weren’t counting on Corbin being this good. What he’s done all year has been impressive. He’s just been consistent from the beginning until now same as Goldy. It’s pretty impressive.”

Corbin has made 25 starts this season most of them dominant but no one disputed the suggestion that this one might have been his best. He threw strikes at an incredible clip always seeming to be ahead in the count. His fastball had life and sink. And his slider the pitch that might be the single biggest reason he has taken such an unexpected jump forward this season was nearly unhittable.

“I think if you look at all the numbers” manager Kirk Gibson said “that was his most dominating performance.”

Corbin has been toxic against left-handed hitters this season holding them to a miniscule .185 average and .495 OPS but to see him dominate the Reds’ tough lefties was stunning. Joey Votto whom many consider the league’s best hitter looked borderline helpless in three of his four at-bats. Slugger Jay Bruce looked even worse. He looked lost.

“When you see a guy like (Votto) looking like he looked against Corbin” Nieves said “he had to have great stuff.”
