Ianetta, Rockies slam Padres

Chris Iannetta hit a go-ahead grand slam in the seventh inning and the Colorado Rockies beat San Diego 9-6 on Monday night, sending the Padres to their sixth straight loss.

Glendon Rusch (2-0) went one inning for the win. Huston Street threw a perfect ninth for his third save in three chances.

The loss, San Diego's 12th in 14 games, dropped the Padres into last place in the NL West, percentage points behind Colorado. The announced crowd of 14,717 was the smallest since Petco Park opened in 2004.

Edwin Moreno (1-3) allowed a leadoff double to Todd Helton before walking Garrett Atkins. Brad Hawpe flied out but Troy Tulowitzki walked to load the bases. Cla Meredith replaced Moreno and grooved a 2-2 pitch that Iannetta hit for his fifth homer.

Adrian Gonzalez went 0-for-4 with three strikeouts for San Diego. It was the first time in 26 games this season that Gonzalez, tied for the NL lead with nine homers, failed to reach base safely.

Scott Hairston hit a three-run homer off Jorge De La Rosa in the fifth inning to put San Diego ahead 6-5. Hairston, who also had a run-scoring single in the Padres' three-run third, tied his career high for RBIs and went 3-for-4.

Colorado got sacrifice flies from Ryan Spilborghs and Tulowitzki, who also had an RBI double and scored two runs.

De La Rosa allowed just three hits in five innings, but his throwing error led to three unearned runs in the third.

After a leadoff walk and a single, Padres starter Kevin Correia laid down a sacrifice. De La Rosa fielded the ball in plenty of time but his throw sailed over first, allowing Henry Blanco to score. Brian Giles' groundout drove in another run before Hairston's RBI single cut the Rockies' lead to 4-3.

Correia allowed five runs and eight hits in 3 1-3 innings.
