Carlos Gonzalez’s two-run homer — Colorado’s fourth overall — broke an eighth-inning tie and sent the Rockies to a 10-7 victory over the Cincinnati Reds on Monday night in a game that featured a long rain delay and seven homers in all.

Seth Smith hit a pair of two-run homers for the Rockies, the fifth multihomer game of his career. Gonzalez snapped a 7-all tie with the first homer allowed by left-hander Bill Bray (2-2) this season. Todd Helton also homered.

Matt Belisle (6-4) pitched out of a threat in the seventh and Huston Street worked the ninth for his 29th save in 32 chances.

Jay Bruce, Drew Stubbs and Brandon Phillips homered for the Reds, who have lost five of seven.

Colorado’s four homers matched its season high and the seven homers combined accounted for 15 of the 17 runs scored.

Bruce got it started with a three-run homer in the first inning off Jason Hammel, his first since July 9.

Smith hit a pair of two-run homers off Reds starter Homer Bailey, putting the Rockies up 5-3. Manager Dusty Baker decided not to bring Bailey back following a 1-hour, 34-minute rain delay in the middle of the third inning — the first this season at Great American Ball Park.

Manager Jim Tracy chose to let Hammel return after the long delay, a move that quickly backfired. Bruce singled home a run in the third, and Stubbs hit a two-run homer for a 6-5 lead.

The rain returned from time to time, though not heavy enough to stop the game again.

The homers kept coming, too.

Helton hit a two-run shot in the fifth for a 7-6 lead. The Reds tied it in the seventh on Phillips’ second career pinch-hit homer. The second baseman was out of the lineup for the second straight day with a sore right ankle, but hit the first pitch from Rex Brothers into the upper deck in left field.

Gonzalez’s 16th homer put the Rockies ahead again. Mark Ellis doubled home a run in the ninth.
