SAN DIEGO (AP) -- The San Diego Padres gave Colorado just enough of an opening, and that's all it took to blow a chance at getting their first series sweep of the season.
Left-hander Christian Friedrich pitched six solid innings to win his major league debut and Jason Giambi and Wilin Rosario hit RBI doubles off the top of the fences at Petco Park as the Rockies rallied to beat the Padres 6-2 Tuesday and snap a five-game losing streak.
It was just the second time in 12 road games that the Rockies scored more than four runs. The Rockies had 13 hits, including at least one by every regular.
Friedrich (1-0) held San Diego to two runs, one earned, on six hits while striking out seven and walking one. He was Colorado's first-round pick in the 2008 amateur draft.
With two starters on the disabled list, the Rockies called up Friedrich and Alex White to get them through this three-game series. White pitched well in a 3-1 loss Tuesday night.
The Rockies scored four unearned runs in the sixth against Anthony Bass (1-4) after shortstop Andy Parrino committed a fielding error on Jonathan Herrera's grounder with one out. Carlos Gonzalez doubled and Michael Cuddyer followed with a sacrifice fly. Giambi was intentionally walked before Rosario hit a high fly ball that bounced off the top of the fence in left, bringing in Gonzalez and Giambi. The umpires reviewed the hit on video but upheld the double. Chris Nelson singled in Giambi for a 5-2 lead.
"It doesn't affect my game at all," Bass said of the error. "I still just have to make my pitches.
"It seemed like everything I threw they hit. I thought they hit a couple of good pitches. It was just one of those innings. I was just one pitch away. Unfortunately, I couldn't get out of it."
Nelson hit another RBI single in the eighth.
Each team had a runner thrown out at the plate.
In the fourth, Gonzalez and Cuddyer hit one-out singles. Giambi doubled off the top of the fence in center field, sending Gonzalez and Cuddyer racing home. Gonzalez scored but Cuddyer was thrown out on Parrino's relay throw.
The umpires reviewed Giambi's hit and upheld the double.
In the third, San Diego's Cameron Maybin reached on a one-out throwing error by shortstop Marco Scutaro and Chase Headley followed with a single to right. Yonder Alonso doubled to left to bring in Maybin for a 2-0 lead. When it looked like left fielder Gonzalez might try to throw to second, Headley hesitated and then broke for home and Gonzalez threw him out.
Friedridch allowed a walk and two singles in the first, including Alonso's RBI single,
Bass allowed five runs, one earned, and nine hits in 5 2-3 innings, struck out four and walked one.
NOTES: Rockies manager Jim Tracy said RHP Jeremy Guthrie is scheduled to make a rehab start for Class A Modesto on Thursday. If all goes well, he could be activated in time to start Tuesday night at San Francisco. Guthrie is on the 15-disabled list with a shoulder injury sustained in a fall from his bicycle. ... Both teams are off Thursday. The Rockies open a three-game series Friday night at Los Angeles, with Jamie Moyer (1-2, 4.01) scheduled to face Chris Capuano (4-0, 2.21) in a matchup of lefties.
