CINCINNATI (AP) -- Miguel Montero drove in four runs with a bases-loaded double and a solo homer Monday night, leading the Arizona Diamondbacks to a 5-3 win shortly after the Cincinnati Reds learned they'll have to try to hold onto first place in the NL Central without Joey Votto.
An MRI found the first baseman has torn cartilage in his left knee that will require surgery and sideline him for three to four weeks.
The slumping Diamondbacks scored four runs in the first off Bronson Arroyo (4-6), who lasted a season-low three innings. The Reds had gotten impressive starts during a six-game winning streak that boosted them into first.
All-Star Wade Miley (10-5) gave up three runs in 5 2-3 innings for Arizona. J.J. Putz got his 17th save in 20 chances.
As the game was starting, the Reds learned about Votto's injury. The slugger hurt his left knee while sliding on June 29, but kept playing. He started for the National League in the All-Star game on Tuesday, and played all three games of a sweep over the St. Louis Cardinals that left Cincinnati alone in first place in the NL Central.
With the knee still sore, he had the test on Monday evening. He'll have surgery on Tuesday, costing the Reds their top hitter. Votto is batting .342 and leads the NL in doubles, walks and extra-base hits.
Arizona manager Kirk Gibson revamped his struggling lineup, which scored a total of three runs while getting swept over the weekend at Wrigley Field. The biggest switch was dropping Justin Upton - in a 1-for-10 slump - to the fifth spot for the first time this season.
The Diamondbacks scored four runs before making an out against Arroyo, who looked out of sync from his nine-day layoff over the All-Star break. Stephen Drew, Willie Bloomquist and Aaron Hill singled, and Montero - in a 6-for-32 slide - doubled home all three runners on Arroyo's 10th pitch of the game.
Upton followed with a single for a 4-0 lead, getting the Reds' bullpen busy. Montero led off the third with his ninth homer, making it 69 straight games at Great American Ball Park with at least one homer. It's the longest streak since an 80-game stretch at Coors Field from 2002-03.
Arroyo was coming off a three-hit shutout in San Diego. He gave up eight hits and five runs in only three innings on Monday night, leaving after 48 pitches.
Miley, who pitched in the All-Star game on Tuesday, also struggled at the start. The left-hander gave up an RBI double by Brandon Phillips in the first inning and a two-run single by Drew Stubbs in the second. He settled down after that hit, retiring the next 11 batters.
The Reds kept it 5-3 with a weird play in the seventh. Bill Bray threw a ball over the plate after catcher Ryan Hanigan stepped out to complete an intentional walk to Chris Young. Montero tried to score from third but was tagged out.
NOTES: Todd Frazier started in Votto's place and went 1 for 4. The Reds plan to make a roster move on Wednesday. ... The blister on RHP Johnny Cueto's right index finger was better, so he'll make his scheduled start on Tuesday against Arizona. ... Diamondbacks OF Jason Kubel was out of the lineup for the third straight game because of a sore hamstring. Gibson said there was no thought of putting him on the DL for now. ... Diamondbacks broadcaster Jeff Munn was in a Cincinnati chili parlor when President Obama walked in on Monday during a campaign visit.
