The road weary Padres made the most of their first game back at Petco Park in more than two weeks. Starting pitcher and local product Sean O'Sullivan pitched well for the Friars. He went six innings allowing five hits with only one earned run. Reds starter Mike Leake, also a local product, actually out-pitched O'Sullivan. Leake left the game after seven innings after allowing just four hits and no runs. Despite their success neither pitcher was involved in the decision.

With the Reds up 1-0 in the ninth closer Aroldis Chapman ran into trouble with the very first batter. Yonder Alonzo managed to get aboard with a walk. Up stepped pinch-hitter Chris Denorfia, who promptly deposited Chapman's 98-MPH fastball over the center field wall to end the game. Denorfia's pinch-hit walk-off homer was the first of his career. The Padres 2-1 win was their third victory in a row.

Game two of the three game series is Tuesday night at Petco Park.
