Rookie outfielder Franmil Reyes hit the first walk-off home run of his career with two out in the 13th inning Thursday night to give the host San Diego Padres a 3-2 victory over the Colorado Rockies.

Reyes sent a 1-1 pitch from right-hander Bryan Shaw over the wall in center for his 12th homer of the season.

The loss was costly for the Rockies, who slipped back in both the National League West and wild-card standings. Colorado trails first-place Arizona by 1 1/2 games in its division while falling two games behind Milwaukee for the second wild card.

Right-hander Robert Stock (1-1), the seventh pitcher used by the Padres, was credited with his first major league win. Shaw (4-6) took the loss.

There were only nine hits in the marathon, with the Padres going 8 2/3 innings in between hits from Austin Hedges' second-inning RBI triple to Reyes' single in the 11th. The Rockies were hitless until the sixth.

The Padres jumped on Rockies starter German Marquez for two runs in the second, but the right-hander and Colorado fought back to tie the game.

Hunter Renfroe singled to right-center with one out in the bottom of the second and scored on Hedges' first career triple -- a drive that rolled to the wall in right-center. The catcher then scored on a sacrifice fly by Freddy Galvis.

The Rockies scored their first run before they had a hit.

Padres rookie left-hander Eric Lauer, who came off the disabled list (forearm strain) earlier Thursday, didn't allow a hit in the five innings he worked. But he hit a batter and issued two walks which came back to burn him for an unearned run.

Lauer hit Trevor Story in the back with one out in the fourth, then issued a second straight walk to Matt Holliday. Story took third on Carlos Gonzalez's deep fly to center and scored when third baseman Wil Myers bobbled Ian Desmond's grounder for the first of his two errors on back-to-back plays.

The Rockies tied the game in the sixth against rookie reliever Trey Wingenter. Story drew a leadoff walk and advanced to third on a single by Holliday to break up the no-hit bid. Story scored when the Padres were unable to turn what would have been an inning-ending double play on a Desmond grounder.

After Hedges' triple, Marquez retired 17 of the next 18 Padres he faced, with the only runner reaching on a rare error by Rockies third baseman Nolan Arenado. Marquez finished with two runs allowed on two hits and a walk with a career-high 13 strikeouts in eight innings.

The Padres committed four errors in the game, three charged to Myers.
