Rockies 17, Reds 7
DENVER -- The Colorado Rockies hit five home runs Sunday, three of them during a 10-run third inning, and walloped the Cincinnati Reds 17-7.
Rockies first baseman Ben Paulsen and right fielder Carlos Gonzalez each homered twice.
Paulsen recorded his first multi-homer game, and he has seven home runs on the season. He set single-game career highs with four hits and four RBIs as the Rockies reached a season high in runs and matched their most lopsided victory margin of the season.
Paulsen finished a double shy of the cycle when he struck out on his final at-bat in the seventh.
Gonzalez tied career highs with six RBIs and four runs. Gonzalez has eight home runs this month, giving him 18 this season.
Third baseman Nolan Arenado began the scoring in the 10-run third with a two-run homer. It was 25th homer of the season and ended a drought of 76 at-bats without a homer since he went deep twice on June 28 at San Francisco.
The inning was the Rockies' biggest since they scored 11 runs against the New York Mets on April 27, 2012. Six of the Rockies' eight hits in the third went for extra bases -- three homers, two doubles and a triple.
Paulsen followed Arenado's homer with his sixth of the season, and Gonzalez capped the inning with a two-run homer. The previous time the Rockies hit three homers in one inning was May 27, 2010, against Arizona.
Paulsen led off the fourth with a homer, and Gonzalez belted a three-run shot in the fifth.
The 17 runs were one more than the Rockies scored in their previous four games combined.
Right fielder Jay Bruce, who drove in four runs, put Cincinnati ahead 4-2 with a three-run homer in the third off Kyle Kendrick (4-11).
Bruce's homer was the major league leading 25th off Kendrick, who needed 102 pitches to get through five innings. Kendrick allowed seven hits and six runs as his ERA crept up to 6.33. The win was just the second in 10 starts for him at Coors Field, where he is 2-5 with a 7.27 ERA.
The Rockies pounded starter Michael Lorenzen (3-5), who lasted 2 1/3 innings, and reliever Dylan Axelrod, who pitched 1 2/3 innings. Each allowed eight runs.
Rockies second baseman DJ LeMahieu went 2-for-4 with two RBIs and three runs. He extended his career-high hitting streak to 16 games.
Reds shortstop Eugenio Suarez finished with three hits.
