SAN DIEGO - Chase Headley hit a two-run homer in the 10th inning to give the San Diego Padres a 7-5 win over the Pittsburgh Pirates late Tuesday night.
Headley's home run came off Daniel McCutchen (0-1) and gave San Diego its fourth straight win.
McCutchen issued a leadoff walk to Will Venable, who stole second before Headley hit his 21st homer. The home run was Headley's ninth this month with 26 RBIs, both major-league highs.
Venable and Cameron Maybin each tied their career high with four hits. It was the second time in three games that Maybin has equaled his mark.
Miles Mikolas (2-1) pitched one inning for the win.
Pittsburgh dropped 7 1/2 games behind first-place Cincinnati in the NL Central. The Pirates are one-half game ahead of Los Angeles and St. Louis for the second wild-card slot.
Garrett Jones sent the game into extra innings with a two-run homer with two outs in the top of the ninth inning with the Pirates trailing, 5-3.
