CINCINNATI - Paul Goldschmidt doesn't keep track of his RBIs. The rest of the Diamondbacks are voluntarily doing it for him.
Goldschmidt set a Diamondbacks record with his third grand slam of the season on Tuesday night and became the first NL player to drive in 100 runs, powering Arizona to a 5-2 victory over the Cincinnati Reds.
Goldschmidt connected in the eighth inning off J.J. Hoover, ending the reliever's streak of 23 scoreless appearances. His 31st homer tied him with Pittsburgh's Pedro Alvarez for the NL lead. All of his career grand slams have come this season.
"I hope he's got a big run left in him," manager Kirk Gibson said. "The team feeds off Patrick (Corbin) and Goldy. They've been our most consistent guys all year."
Goldschmidt knew his RBI total was in the 90s coming into that at-bat, but didn't realize he'd reached triple digits until he rounded the bases and his teammates pointed it out.
They don't mind doing the counting.
"He's impressive to watch play every day," catcher Wil Nieves said. "He's so clutch. He's unbelievable."
Corbin (13-3) stymied Cincinnati's lefty-dominated lineup, allowing six hits, including Chris Heisey's two-run homer, during his second complete game. Corbin matched his career high with 10 strikeouts. He threw first-pitch strikes to 27 of the 33 batters he faced and didn't walk a batter in his most dominating performance of the season.
"Today I had my best slider," Corbin said. "I felt good warming up in the bullpen. I thought it would be a good game. I knew I could go to my slider at any time."
The left-hander shut down the Reds' left-handed threats - Shin-Soo Choo, Joey Votto and Jay Bruce were a combined 0 for 12 with seven strikeouts.
"He makes some of their hitters look so bad - and they're unbelievable hitters, especially Votto and Bruce," Nieves said.
The D-backs evened their series at a game apiece and moved five games behind the Reds for the final NL wild card berth. Arizona has won six of its last eight games.
"We've got some work to do," Goldschmidt said. "There's some good teams ahead of us. It's not like we're one game behind."
Cincinnati lost for only the fourth time in its last 14 games. A bigger concern: Tony Cingrani (6-3) left in the fourth inning with a strained lower back.
The left-hander has been filling in for Johnny Cueto, who is on the disabled list for the third time this season.
