DENVER (AP) - Marco Scutaro's RBI single in the 11th inning gave Colorado an 11-10 victory over the Washington Nationals on Thursday after the Rockies squandered a seven-run lead.
Jonathan Herrera doubled with one out off Craig Stammen (3-1). After pinch-hitter Jason Giambi walked, Dexter Fowler hit a fly ball to deep center that was caught by Bryce Harper. Herrera tagged up and took third on the play with pinch-runner Christian Friedrich advancing to second.
Scutaro, who was 13 for 68 with runners in scoring position, then completed a seven-pitch at-bat with a single to right-center.
Adam Ottavino (2-0) pitched two scoreless innings and struck out five, including all three batters in the 11th.
Harper's homer in the ninth off Colorado closer Rafael Betancourt tied the score and sent the game into extra innings.
Tyler Colvin had a career-high four hits, including a three-run homer in Colorado's five-run first, and also set career-bests with five RBIs and nine total bases.
Chris Nelson had an RBI double in the second and scored on Colvin's single to make it 7-0.
Ryan Zimmerman had a two-run single and Michael Morse hit a three-run homer to pull Washington within two in the third.
After the Rockies scored two in the fourth on Carlos Gonzalez's RBI signle and Colvin's run-scoring triple, Ian Desmond hit a two-run homer to cap Washington's four-run fifth that tied the score at 9-all.
Adam LaRoche hit a sacrifice fly, and Ian Desmond hit his 13th homer of the season in the Nationals' fifth.
The Rockies went ahead in their half of the sixth against Tom Gorzelanny when they loaded the bases with no outs on two singles and a walk, and Gonzalez grounded into a double play.
For the second straight start, Josh Outman was staked to a big lead by the Rockies but was unable to pitch the five innings needed to qualify for a win on the 75-pitch limit the Rockies are using for their four starters.
Outman, who lasted three innings, took the mound in his final inning with the seven-run lead and gave up the five runs with two out.
Gonzalez had an RBI single and Nelson added a run-scoring infield single with the bases loaded in the first, with Gonzalez getting caught after rounding too far off third. Colvin then followed with his eighth homer of the season.
Notes: Morse left Wednesday night's game in the eighth with a tight right hamstring and stayed in the clubhouse late taking treatment. Nationals manager Davey Johnson was planning to sit Morse on Thursday but changed his mind when Morse said he was fine and able to play. ... Rockies manager Jim Tracy said RF Michael Cuddyer was given a day to regroup. He entered the game in the 11th at first base. Cuddyer began the day with seven hits in his last 51 at-bats and was 2 for 12 in the first three games of the series. 1B Todd Helton hit fourth for the third time this season in Cuddyer's place, something he last did April 15, and Chris Nelson batted fifth for the first time this season. ... Rockies 3B Jordan Pacheco wasn't in the lineup due to soreness in his left quadriceps, which has bothered him off and on recently. He pinch hit in the ninth and had a sacrifice bunt. ... Jeff Francis (0-1) will start for the Rockies against the San Diego Padres on Friday when the Nationals will start Ross Detwiler (4-3) at Atlanta.
