Padres Keep On Losing, Drop Eighth Straight, 4-3, To Rockies

San Diego, CA (Sports Network) - Jason Giambi and Troy Tulowitzki each hit a two-run homer, as the Colorado Rockies dealt San Diego an eighth consecutive defeat, 4-3, in the opener of a three-game series.

Aaron Cook (5-8), who was activated off the disabled list to make the start, got the win after limiting the Padres to two runs on four hits and four walks in 6 1/3 innings.

Meanwhile, San Diego's worst losing streak of the season continued with Friday's loss, but it did not lose any ground in the division. The Padres still hold a three-game lead over San Francisco because the Giants lost to Los Angeles on Friday.

Cory Luebke (0-1) made his major league debut for San Diego and pitched five innings in taking the loss. He walked two and allowed five hits, two of which were Colorado's home runs.

Luebke gave up Giambi's homer in the second inning, following a leadoff triple by Melvin Mora. The Rockies repeated that pattern in the third, when Carlos Gonzalez led off with a single before scoring on Tulowitzki's blast to center.

Armed with a 4-0 lead, Cook didn't run into serious trouble until the sixth, when he walked the bases loaded with one out. However, the Padres got only one run out of the situation, on a Chase Headley groundout. Will Venable popped out to end the threat.

But in the seventh, Chris Denorfia doubled with one away, prompting a pitching change. Samuel Deduno entered, but pinch-hitter Nick Hundley greeted him by blasting a homer to left field to bring the Padres within a run.

Deduno then walked David Eckstein before getting the second out of the inning before Franklin Morales was brought in to face Adrian Gonzalez, who singled. However, Rafael Betancourt entered and got the final out, then pitched a 1-2-3 eighth.

Huston Street pitched a scoreless ninth for his 14th save.
