The Los Angeles Dodgers took a step back in their bid to win the NL West after failing to come up with the timely hits that had keyed their winning streak and dominance against the Colorado Rockies.
Rediscovering that effort at the plate could be difficult against Jorge De La Rosa at Coors Field.
The West-leading Dodgers look to avoid their first back-to-back losses of September on Wednesday while denying the NL-worst Rockies their eighth straight home win when De La Rosa starts.
Los Angeles (86-65) built a four-game division lead by outscoring its opponents 32-5 during a three-game winning streak that included two victories over second-place San Francisco.
The club also had averaged 6.0 runs while winning 10 of 14 in the season series following Monday's 11-3 win at Colorado.
The Dodgers finished with 16 hits in Tuesday's 10-4 loss, but only scored twice before Yasiel Puig's two-run homer in the ninth inning. They went 3 for 14 with runners in scoring position after going 20 for 45 in the previous three games.
Los Angeles fell 1 1/2 games behind Washington for the NL's best record while the Giants cut a game off their division lead.
''Just one of those days, I guess,'' second baseman Dee Gordon said. ''Time to turn the page.''
Justin Turner filled in nicely for the injured Hanley Ramirez with three hits, two doubles and two RBIs. Ramirez was a late scratch because of a strained right elbow and is day to day.
Matt Kemp, who added two hits, is batting .404 with three home runs and 13 RBIs in his last 13 games against the Rockies. He's also batting .417 with three homers in 36 at-bats versus De La Rosa (13-11, 4.28 ERA).
De La Rosa has been at his best at home, winning six consecutive decisions and going 9-2 with 3.30 ERA on the season.
Los Angeles was the last team to beat De La Rosa at Coors, tagging him for five runs over 5 1-3 innings in a 6-1 victory June 8. Almost a month later, he limited the Dodgers to two runs and three hits over six innings in an 8-7 home win.
The left-hander has gone 2-2 with a 6.23 ERA in four meetings this season and 4-10 with a 5.94 mark in 16 for his career.
Ramirez is hitting .393 with two homers in 28 career at-bats off him, while Adrian Gonzalez has a .341 average with three homers in his 41 at-bats.
Colorado (60-91) totaled 11 runs during a seven-game losing streak before nearly matching that output Tuesday.
''Our offensive execution has been lacking and it was real good tonight,'' manager Walt Weiss said.
Corey Dickerson went 2 for 4 with a home run and four RBIs after going 4 for 25 in his previous seven contests. Justin Morneau had two hits to raise his average to .316, moving within one percentage point of Pittsburgh's Josh Harrison, the NL leader.
Los Angeles rookie Carlos Frias makes his second career start while Hyun-Jin Ryu rests a sore left shoulder.
Frias (0-0, 3.91) allowed just three hits over six shutout innings in an 8-5, 14-inning home loss to Washington on Sept. 3. The right-hander had worked 11 straight scoreless innings before allowing two runs in relief of Ryu on Friday.
Colorado's Nolan Arenado has been sidelined indefinitely because of a bruised chest and pneumonia.
