DENVER (AP) - Edwin Jackson was pounded once again at Coors Field. But the Washington starter wasn't about to blame the ballpark for his poor showing.
``The park is definitely not an excuse,' Jackson said. ``At the end of the day, you have to go out and get the job done and I didn't do a great job today.'
Marco Scutaro's RBI single in the 11th inning gave Colorado an 11-10 victory over Nationals on Thursday after the Rockies squandered a seven-run lead.
Jackson is 0-1 with a 17.40 ERA in four starts at Coors Field. He was tagged this time for a season-high eight runs on 10 hits in only three innings.
``I feel the loss was on me,' Jackson said. ``It's not a great feeling when you are the starter and the bullpen has to come in in the fourth inning.'
The short outing put added pressure on an already spent relief corps.
``Our bullpen was used up,' Nationals manager Davey Johnson said. ``We were on our last usable guy and had only Chien-Ming Wang left.'
Jonathan Herrera doubled with one out in the 11th 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, and pinch-runner Christian Friedrich later took 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.
Harper's homer in the ninth off Colorado closer Rafael Betancourt tied the score and sent the game into extra innings. It was his first homer since June 12 in Toronto.
The homer provided Harper and the Nationals some encouragement. Harper struck out eight times and hit into two double plays while going 5 for 21 in the four-game series.
``The whole series they pitched me out, out, out, up, out,' Harper said. ``They didn't throw me one strike the whole series.'
Adam Ottavino (2-0) pitched two scoreless innings and struck out five, including all three batters in the 11th.
Tyler Colvin had a career-high four hits, including a three-run homer in Colorado's five-run first, and also set a career-best with five RBIs.
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 single 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. Johnson was planning to sit Morse on Thursday but changed his mind when Morse said he was fine and able to play. ... The Nationals will start Ross Detwiler (4-3) at Atlanta on Friday. ... Washington is 5-5 in extra-inning games. ... Desmond leads all major league shortstops with 37 extra-base hits and had eight in the series.
