Associated Press - Chris Denorfia hit a two-run, pinch-hit homer off Aroldis Chapman in the bottom of the ninth inning to give the San Diego Padres a 2-1 victory over the Cincinnati Reds on Monday night.
Chapman (3-4) walked leadoff batter Yonder Alonso on a 3-2 pitch, then Denorfia drove a 98 mph first-pitch offering from Chapman over the center-field fence 423 feet away to deal the Reds their fourth straight loss.
Luke Gregerson (5-5) pitched the ninth for the win. Mike Leake and Sean O'Sullivan, two San Diego natives, matched up against each other. Leake went seven scoreless innings, allowing four singles.
O'Sullivan, making his third start for the season for the Padres, went six innings and allowed one run on five hits. He walked five and struck out one.
Reds center fielder Derrick Robinson led off the fifth with a triple off the fence in left-center. He scored when Cesar Izturis hit a grounder to first, which Alonso grabbed, touched first base for the putout then fired home, but Robinson just beat the throw to catcher Nick Hundley.
That snapped a scoreless streak of 22 innings for the Reds going back to the second inning of Saturday night's game against the Dodgers in Los Angeles. They have scored just three runs in their last four games.
Cincinnati loaded the bases in the fifth, but O'Sullivan got Devin Mesoraco to hit a grounder to short.
The teams combined to leave 15 runners on base through the first five innings -- nine for the Reds. They also left the bases loaded in the first, while the Padres left them loaded in the third.
Leake got Mark Kotsay to ground to first baseman Joey Votto with the bases loaded to end the third. The only batter to reach after the third against Leake was Everth Cabrera, who got on with an infield single leading off the fifth, but he was caught stealing by Mesoraco. Cabrera had two of the four hits off Leake.
