Miley was dominant for seven innings, Colorado takes lead in eighth, but Arizona rallied in ninth to tie the score and then Colorado piles on four in the 13th to win it.
It looked like it would be a quick night and a somewhat historic one for Wade Miley and the Arizona Diamondbacks. With a shot to pick up his 17th win of the year to tie a rookie mark that had not been bested since 1976, Miley was masterful for seven innings. However, a two-run eighth inning rally by Colorado ruined those chances, but a ninth inning homer by Paul Goldschmidt sent the game into extra innings and eventually the Colorado Rockies ended the game with a 4-3 13-inning win.
To start the scoring, in the bottom of the first, second baseman Aaron Hill homered for the 25th time this season to give the D-backs a 1-0 lead. Gerardo Parra would add to that lead and make it 2-0 on a solo shot in the fifth.
Meanwhile, Miley made quick work of the Rockies. He struck out six batters in the first three innings and allowed only two hits through six innings.
In the top of the seventh, the Rockies finally got to Miley, when catcher Wilin Rosario homered with one out to make the game 2-1. It was Rosario's 28th homer of the year.
Miley would take a 2-1 lead into the eighth inning. Charlie Blackmon led off with a bunt single and, with two outs, Josh Rutledge and Tyler Colvin hit consecutive doubles to chase Miley and take the lead.
Miley finished the game striking out a career-high 10 batters, but allowed the three runs on six hits.
Arizona, facing Colorado's closer Rafael Betancourt, tied the score on a Paul Goldschmidt homer, taking Miley off the hook.
Going into extra innings, neither team scored in the 10th or 11th innings, but Colorado threatened. In both the 11th and 12th, facing Bryan Shaw, the Rockies had two runners on. In the 11th, they hit into a double play and in the 12th, Shaw struck out Rutledge to end the threats.
The Rockies scored in the 13th inning when Tyler Colvin doubled to lead off the inning off of Brad Bergesen and Chris Nelson singled to bring him home. After Bergesen walked the bases loaded, Mike Zagurski relieved him and gave up a run-scoring hit to Charlie Blackmon to make it 5-3. A fielder's choice to third with no out resulted in another run to make it 6-3 and a wild pitch made it 7-3.
Josh Outman pitched two-thirds of an inning to pick up his first win of the year. Josh Roenicke got the final two outs, but allowed two runs to score.
Bergeson was tagged with the loss, his first of the season.
