SAN FRANCISCO _ Franmil Reyes had been hitting balls hard all over the field.
The big man finally sent one where nobody would catch it.
His 426-foot, pinch-hit home run in the seventh inning tore through the misty fog at 112.9 mph to complete a comeback by the new San Diego Padres, and three relievers closed out a 6-5 victory over the San Francisco Giants at Oracle Park.
The Padres, so often punchless in recent seasons, especially when trailing late, scored in three straight innings to work back from a 5-0 hole. Monday was the fifth time in 11 games (seven victories) they have scored the winning run in the sixth inning or later.
Fernando Tatis Jr.'s two-run homer in the fifth inning was the first hit off Giants starter Madison Bumgarner. Wil Myers hit a solo homer in the sixth.
In the seventh, Bumgarner came in too far on a full-count fastball and hit Tatis for the second time in the game. Francisco Mejia followed with a high fly ball that bounced near the top of the brick facade in right field for a double that sent Tatis to third.
With reliever Reyes Moronta in, Manuel Margot's grounder to shortstop scored Tatis.
Reyes, whose .091 batting average was the lowest in the majors among players who had appeared in 10 games despite the fact his 93 mph average exit velocity was second highest on the Padres, checked in for Padres starter Eric Lauer and hit the first pitch he saw through the night and just inside the left-field foul pole for his first home run (and third hit of the season).
Brad Wieck, pitching on the day of his call-up from Triple-A, fewer than three months after surgery for testicular cancer, worked the seventh. Craig Stammen followed in the eighth. Kirby Yates worked the ninth to earn his sixth save.
Kevin Pillar's grand slam had punctuated a five-run fourth inning against Lauer, who allowed four runs in the third inning of an 8-5 loss to the Arizona Diamondbacks six days earlier.
This time, the Padres were able to pick him all the way back up.
Lauer (2-1) is the only Padres pitcher to go six innings this season, doing so in both his starts against the Giants.
