MILWAUKEE - Wearing dark sunglasses, manager Ron Roenicke looked on calmly with arms folded across his chest after his Milwaukee Brewers just had a "meltdown."

Three runs scoring on two errors in one wild fifth-inning sequence helped add up to a sloppy 10-4 loss Sunday to the Colorado Rockies.

The Brewers looked like a team that could use a break after wrapping up a stretch of 20 games in 20 days, though Roenicke was unsure how much fatigue may have played a role in the fifth.

"You can have those plays any time," Roenicke said. "You get down when you see it, so it's hard to bounce back after a play like that."

Wilin Rosario took advantage of the gaffes with runners on first and second. His shot to third was booted by normally sure-handed third baseman Aramis Ramirez.

The sun was bright and shadows were creeping across the infield at the time, though Ramirez wasn't looking for vindication.

"No excuses. I should have made that play," Ramirez said.

One run had already scored when the ball squirted into foul territory. Shortstop Jeff Bianchi threw home high and offline trying to get Corey Dickerson. Catcher Jonathan Lucroy then threw errantly while attempting to get Rosario at third, and Rosario hustled home safely for a six-run lead.

Jorge De La Rosa (8-6) got the win despite allowing three wild pitches and hitting one batter. Milwaukee's Yovani Gallardo (5-5) was tagged for 10 hits in five innings.

The Rockies had jumped on Gallardo for a 5-0 lead through three innings — quite an accomplishment after the right-hander had allowed just three in his previous four starts combined. Colorado snapped a six-game slide to Milwaukee in the clubs' last meeting of the regular season.

A curveball that had flustered hitters the past few weeks disappeared on Sunday. An off day Monday couldn't have come at a better time.

"It was just one of those days, to be honest," Gallardo said. "Today was just ... I mean, I wish I knew where (the curveball) went."

Ryan Braun slugged an opposite-field solo shot into the Rockies bullpen in right for his 11th homer. Braun also doubled in the sixth and scored on one of two wild pitches by De La Rosa in the inning.

"Those wild pitches I (made), that cost some runs, De La Rosa said. "But the most important thing, we win."

Khris Davis' RBI groundout later in the sixth made it 8-4 when Ramirez scored following a steal of third. Ramirez, 36, stole two bases in a game for the first time in his 17-year career.

It could have been much closer if not for the Milwaukee miscues in the fifth that had the National League's best team resembling a Little League outfit. Roenicke watched calmly in the dugout after the 220-pound Rosario chugged home.

"Yeah, it's a home run, that's a home run for Rosario," Rockies manager Walt Weiss said. "One of the turning points if not the turning point of the game."

De La Rosa allowed four hits, two walks and four runs in six innings.

NOTES: Dickerson opened the scoring with a two-run double in the first. He left with a left hamstring cramp following a 1-1 count in the eighth after fouling off a pitch. ... The Rockies want 3B Nolan Arenado to get about 25 at-bats in a rehab assignment with Triple-A Colorado Springs before returning to the lineup. Arenado has been on the disabled list since May 24 after breaking his left middle finger on a head-first slide into second in Atlanta. He started the rehab assignment Saturday. ... Roenicke hoped to get OF Carlos Gomez (neck strain) and SS Jean Segura (left quad) back for the start of a two-day interleague series Tuesday at Toronto. RH Marco Estrada (7-4) is scheduled to get the start. ... LHP Yohan Flande (0-0) will make his second career start when Colorado opens a three-game series Monday in Washington.
