Chase Headley and Yonder Alonso each launched a two-run homer and Carlos Quentin added a solo shot Sunday in San Diego\'s 7-3 win over the New York Mets. Headley\'s blast in the first inning put the Padres ahead to stay, while Alonso\'s clout in the third handed San Diego a 5-0 lead. Quentin also contributed a run-scoring double for the Padres, who took the rubber match of a three-game series. Jason Marquis (5-6) collected the victory, yielding three runs on four hits over 6 1/3 frames. The right-hander won for the fourth time in five starts, allowing one walk while striking out five. New York\'s Matt Harvey (1-2) absorbed the loss in his third major league start, surrendering five runs on eight hits over five full frames. Ronny Cedeno cracked a pinch-hit, two-run homer for the Mets.
