(My Sportsbook) - Aaron Cook will try to avoid a second straight loss to the Dodgers tonight, as his Colorado Rockies begin a three-game set with Los Angeles at Coors Field.

A 16-game winner last season, Cook has yet to find the win column in 2009. In his last outing on Saturday in Los Angeles, the right-hander was beat up for five runs on eight hits in four innings of a 9-5 setback. Three of those hits were home runs, including two by Manny Ramirez and one by Andre Ethier.

Cook fell to 5-6 with a 4.13 earned run average in 19 career outings versus the Dodgers, 14 of those starts, and the setback was just one of five in Colorado's last six games.

The Rockies also went just 2-6 over an eight-game road trip, a swing that included getting swept by the Dodgers in three games from April 17-19, and plated three runs or fewer in five of those games. The doomed trek began with a shutout loss to Chicago back on April 13 and ended with a 2-0 defeat at the hands of Arizona on Wednesday.

Jorge De La Rosa (0-2) was on the wrong end of the decision, surrendering two runs on six hits and four walks while striking out six in 6 2/3 frames. Ryan Spilborghs had four of the Rockies' nine singles, while Brad Hawpe and Seth Smith each had two hits and a walk.

The Dodgers, meanwhile, wrapped up a perfect 6-0 homestand by sweeping the Rockies, but then stumbled on the road a bit. Los Angeles began a nine-game road trip by losing its first two contests in Houston before rebounding with a 2-0 win in the series finale on Thursday. While the Dodgers have yet to lose at home this year (6-0), they improved to just 5-5 as the road club.

Chad Billingsley tossed 7 1/3 shutout innings to become baseball's first four- game winner. He allowed only three hits and two walks to go along with five strikeouts. Jonathan Broxton registered his fifth save of the campaign, working 1 2/3 innings.

Ramirez went 2-for-4 with a run batted in, while Casey Blake knocked in the other run with an RBI double. That effort helped LA to its ninth win in its last 11 games overall. Orlando Hudson had a pair of hits to extend his hitting streak to nine games. He is batting .486 (18-for-37) on the tear with five RBI and 10 runs scored.

Ramirez, meanwhile, is batting .550 (11-for-20) with four homers and eight RBI over a six-game hit streak of his own.

The Dodgers have not seen much of a drop off in production from the back end of their rotation thanks to Eric Stults, who starts tonight.

The left-hander is 2-0 with a 2.61 ERA, defeating Arizona with 5 1/3 innings of one-run ball on April 11 before another victory over San Francisco last Thursday. Stults held the Giants to a pair of runs on five hits and three walks over five innings.

The 29-year-old is 1-0 with a 3.60 ERA in six games (2 starts) lifetime versus the Rockies. He made just one start versus them in 2008, but was hit hard for three runs on six hits and three walks over just 3 2/3 innings.

The Dodgers have won six of their last seven over the Rockies and claimed victory in five of nine at Coors Field last year.
