ATLANTA - Atlanta reliever Billy Wagner blew a two-run lead in the ninth inning, and pinch-hitter Nick Hundley's two-run double in the 12th lifted the San Diego Padres to a 6-4 victory over the Braves on Wednesday night in a matchup of division leaders.
Chris Denorfia led off the 12th with a single off Kris Medlen (6-2), Atlanta's seventh pitcher. Denorfia stole second base as Tony Gwynn Jr. struck out for the second out. An intentional walk to Oscar Salazar put runners on first and second for Hundley, who pinch-hit for Tim Stauffer (3-1).
Hundley's double down the left-field line made it 6-4.
Heath Bell earned his 27th save with three strikeouts in the bottom of the 12th. The game lasted 4 hours, 13 minutes.
It was the fourth blown save for Wagner, who couldn't hold a 4-2 lead in the ninth. The Padres rallied with Scott Hairston's pinch-hit homer, a single by Jerry Hairston and Yorvit Torrealba's tying double to right.
Stauffer pitched two scoreless innings to lower his ERA to 0.33.
