DENVER (AP) _ Moises Alou, Richard Hidalgo and Tony Eusebio hit consecutive homers in the eighth inning as the Houston Astros set a team record with six home runs an 8-4 victory over the Colorado Rockies on Wednesday night.

Alou homered twice and Jeff Bagwell and Lance Berkman added solo shots for the Astros, who handed Rockies starter Pedro Astacio his first loss since April 9. Astacio (6-3) had won six straight decisions.

Astacio failed to retire the side in order in each of the first seven innings and ran into trouble when he walked Ken Caminiti with the score tied 4-4 to start the eighth.

Alou hit Astacio's next pitch onto the concourse in left field for his 14th career two-homer game. Stan Belinda relieved and gave up homers to Hidalgo and Eusebio, giving the Astros back-to-back-to-back home runs for the second time in team history.

Enos Cabell, Phil Garner and Jose Cruz hit consecutive home runs against the San Francisco Giants at Candlestick Park on July 24, 1984.

Joe Slusarski (1-3) pitched three innings of scoreless relief of Chris Holt for his first victory since August 26, 1995, pitching for Milwaukee against Minnesota. Holt gave up four runs and seven hits in six innings.

The Astros, who won consecutive games for the first time since May 25-26, trailed 4-3 before Alou led off the sixth with a solo homer, his eighth. The Rockies had taken the lead on Jeff Cirillo's RBI triple in the fifth.

Berkman hit his sixth homer in the fifth and Bagwell connected for his 16th of the season in the third. Bagwell also had an RBI single in the first.
