PHOENIX -- Anthony DeSclafani and Scott Schebler had a night to remember Saturday.

Arizona had one to forget.

DeSclafani threw his first career shutout, one of the 26 in the major leagues this season, and Schebler had his first two-homer game while getting a career-high five RBIs and tying a career high with three hits on Saturday night in the Cincinnati Reds' 13-0 victory over the Diamondbacks.

Arizona's silver lining was reliever Vicente Campos, who gave up three runs (two earned) in 5 2/3 innings of long relief in his major league debut. He almost single-handedly saved the Diamondbacks' bullpen for the final game of the series on Sunday.

Cincinnati right-hander Homer Bailey (2-2, 5.73 ERA) will oppose Arizona right-hander Archie Bradley (4-8, 5.06) in the rubber game.

Bailey will make his sixth start of the season after missing the first half recovering from Tommy John surgery, and he has beaten every team in the National League in his career except the Diamondbacks. Bradley has given up 21 earned runs and 36 hits in 23 innings in his five August starts.

Both Bailey and Bradley will have an exceptionally hard act to follow.

DeSclafani was that good. He gave up four hits, all singles, struck out a season-high nine and walked one. Helped by two double plays, he faced only three batters above the minimum and needed only 108 pitches.

Clayton Kershaw (three), Johnny Cueto (two) and Corey Kluber (two) are the only major leaguers with more than one shutout this year.

"It's definitely an accomplishment, for sure," De Sclafani said. "I think every pitcher always wants to throw a complete game shutout, and I am very fortunate to have thrown one. I'm definitely going to enjoy it.

"I was kind of focused the entire game. You start creeping up there, seventh, eighth. Then the ninth inning. You don't want to beat around the bush. Just attack. I got that last out and I didn't realize it happened because I was so locked in."

Schebler had two of the Reds' five homers. He had a two-run homer in the first inning and a three-run homer to cap a five-run second, all the runs scoring with two outs, to give DeSlcafani a manageable cushion.

"Kind of a crazy day," Schebler said. "'Disco' obviously threw the heck out of the ball."

DeSclafani dropped his ERA to 2.92. He missed the first nine weeks of the season with a strained oblique.

"He's a pitcher, in every sense of the word," Cincinnati manager Bryan Price said. "I think he gets it. I think he's a part of the foundation of what can be a really good starting rotation. He's been phenomenal."

Campos, who was recalled from Triple-A Reno on Thursday, helped keep an overworked Arizona bullpen somewhat fresh for Sunday's game. The only damage against him came on two solo homers.

"He gave us a chance to win the series tomorrow," Arizona manager Chip Hale said. "Without his outing, we would have had to use everybody out of the bullpen, and it probably would be a tough game tomorrow to deal with us. He used all his pitches mixed his pitches.

Campos, who was acquired from the Yankees for RHP Tyler Clippard at the trade deadline, was 1-2 with four starts at Double-A Mobile before being recalled Thursday. He was 10-5 with a 3.26 ERA at four minor league levels this season, three with the Yankees.

The Reds' Joey Votto, meanwhile, got closer to becoming the first player since 2010 to hit .400 in back-to-back months. Votto was 2-for-4 with a double and his 21st homer of the season to raise his batting average to .422 in August. He hit .419 in July. The last player to have consecutive .400 months was Texas' Josh Hamilton, who did it in June and July of 2010.

Votto is batting .444 with 34 RBIs in 39 games since the All-Star break.
