The Colorado Rockies (22-29) extended their winning streak to five games last night in Denver with a 13-3 win over the National League West leading Los Angeles Dodgers (32-20). It was the Dodgers’ fifth loss in a row. Game 2 of the three-game series is this afternoon at 2:10 at Coors Field (TV: Root Sports).

The Rockies are missing one of their big guns, with Friday being shortstop Troy Tulowitzki’s second day on the 15-day DL with a left groin strain. But they have found plenty of firepower throughout the lineup.

“What can I say that I haven’t said the last three games?” Rockies manager Jim Tracy said. “We just continue to swing the bats well.”

Todd Helton went 2-for-3 to run his hitting streak to eight games, Carlos Gonzalez went 2-for-4 with an RBI to run his total to 45 and his hit streak to six games (15-for-24, .625) and leadoff man Dexter Fowler had three hits and two RBIs while hitting safely in his sixth straight game.

Throughout a four-game sweep of the Astros, Rockies starting pitching — a problem all season — did well enough to win games that were hard to lose because of the high scoring. Last night, led by a starter trainee, the Rockies pitched well enough to win most any game.

Colorado parted ways with veteran Jamie Moyer this week and moved lefty specialist Josh Outman, who had made 25 starts in 33 appearances with the Athletics the last three years, into the rotation. However, Outman was limited to roughly 50 pitches. He used 55 to hold the Dodgers scoreless for 3 1/3 innings, with two hits, a walk and five strikeouts.
