Brad Hawpe's bases-loaded, two-run single in the bottom of the eighth sparked a six-run rally and the Colorado Rockies beat the Washington Nationals 8-2 on Tuesday night.
Manny Corpas (2-3) pitched one inning in relief of Jorge De La Rosa, who struck out six in seven innings, and Ian Stewart hit his fifth home run of the season for the Rockies.
Luis Ayala (1-7) pitched one-third of an inning and took the loss for the Nationals, who had their four-game winning streak snapped.
The Rockies trailed 2-0 when Stewart hit a two-run homer in the seventh, and they broke open the game in the eighth thanks to four walks and two hit batters by the Washington bullpen.
Ayala relieved starter John Lannan and loaded the bases with one out. Charlie Manning relieved Ayala and Hawpe hit his first pitch to center to score two. Manning walked Troy Tulowitzki and pinch hitter Seth Smith to make it 5-2.
Saul Rivera relieved Manning and hit Willy Taveras to score a run and walked Jeff Baker to drive in another. Matt Holliday, who began the rally with a one-out double, drove in a run on an infield single.
The Rockies sent 12 batters to the plate in the inning and had only three hits.
The Nationals took a 1-0 lead on Rockies starter De La Rosa in the second inning. Austin Kearns led off with a single, moved to third on Lastings Milledge's infield single and a throwing error by Garrett Atkins and scored on a sacrifice fly by Jesus Flores.
Washington took a 2-0 lead in the fifth when Ryan Langerhans scored on a wild pitch.
Lannan was in control until the seventh, striking out seven and allowing three hits. He retired the first two batters in the bottom of the seventh before Clint Barmes hit a bloop single to right and Stewart sent a 1-0 pitch into the right field bleachers to tie the game.
Lannan finished with eight strikeouts.
