DENVER (AP) — Jordan Pacheco’s first home run broke a fifth-inning tie and he added a two-run single in the eighth to lift the Colorado Rockies to a 12-7 victory over the Cincinnati Reds on Saturday.

The teams combined for nine home runs in the first five innings.

The Reds hit five homers off starter Alex White, who tied a Rockies record for homers allowed in a game. White gave up three homers in succession, and he has allowed 12 homers in 37 innings in four starts with the Rockies.

White (2-1), acquired in the July 31 trade that sent pitcher Ubaldo Jimenez to the Cleveland Indians, lasted five innings. Staked to a 6-1 lead after two innings, White gave up a solo homer to Chris Heisey in the third and a two-run shot to Juan Francisco after walking Jay Bruce with two out.

The Reds teed off on White (2-1) with one out in the fifth, when Heisey, Joey Votto and Jay Bruce hit successive home runs in a nine-pitch sequence that tied the game at 7. White regrouped and got two fly ball outs to finish an outing that included just four outs on ground balls.

Pacheco, who was playing in his fourth game in the big leagues, homered against left-hander Matt Maloney (0-2).

The Rockies hit three homers in the first two innings, knocking out Bronson Arroyo and giving him a share of a dubious Reds record. Arroyo has allowed 40 home runs, tying Eric Milton for the team’s single-season mark set in 2005.

Mark Ellis began a four-run barrage in the first with a homer, his fifth since joining the Rockies and fourth at Coors Field. Carlos Gonzalez lined a double off the out-of-town scoreboard in right field, Troy Tulowitzki, back in the lineup after left hip soreness kept him out Friday, singled home Gonzalez.

Jason Giambi hit a two-run homer to straightaway center field for his 13th shot of the season and No. 428 overall. He moved past Mike Piazza and into 42nd place on baseball’s career list.

White led off the second with his first major league hit, a double that went over the head of right fielder Jay Bruce, who was fighting the sun. Dexter Fowler followed with his fifth home run, a drive that hit off the facing of the second deck in right field and finished Arroyo’s day.

White contributed to the Reds’ unearned run in the first. He fielded Heisey’s one-out bunt but threw the ball down the right field line, allowing Heisey to reach third. He scored when Votto singled. Votto reached second when center fielder Fowler bobbled the ball, but White retired Bruce and Francisco to end the inning.

Maloney, the third Reds pitcher, allowed an unearned run in the fourth that put the Rockies ahead 7-4.

The Rockies tacked on four runs in the eighth when pinch hitter Eric Young Jr. led off with a single and dashed to third on Chris Nelson’s one-out single against Sam LeCure. Aroldis Chapman threw a wild pitch that enabled Young to score and walked the two batters he faced. Jeremy Horst came on and walked Giambi with the bases loaded, and then gave up a two-out, two-run single to Pacheco.

Matt Belisle, Rex Brothers, Huston Street and Rafael Betancourt and allowed one hit to Cincinnati over the final four innings

Notes: White is the third Rockies pitcher to allow five home runs in a game but the first to do it after the 2002 installation of the humidor at Coors Field. … Rockies 2B Mark Ellis left the game in the sixth after getting hit in the head by a pitch from Carlos Fisher. Ellis sat up right away after being hit and walked off the field unaided. … The last time the Reds hit three consecutive homers was Aug. 13, 2006, at Philadelphia when Juan Encarnacion, Adam Dunn and Rich Aurilia did it. … Heisey has had three two-homer games in his career, all this season. … Left-hander Drew Pomeranz will make his major league debut and start for the Rockies on Sunday. Edinson Volquez, 5-4 with a 5.93 ERA, will make his first start for the Reds since July 5. He went 3-2 with a 2.47 ERA in 11 starts at Triple-A Louisville after being sent down.
