CINCINNATI, Aug. 11 (UPI) -- After squandering a five-run lead and waiting through a 93-minute rain delay Sunday, the Cincinnati Reds emerged with a 9-7 victory over the San Diego Padres on Aaron Boone's two-run homer with one out in the bottom of the 12th inning.
After Todd Walker doubled, Boone hit an 0-2 pitch from Brandon Villafuerte (1-1) over the left-field fence nearly 6 1/2 hours after the first pitch, giving the Reds a sweep of the three-game series.
Jose Rijo (5-3), the Reds' sixth pitcher, tossed a scoreless inning for the win.
Cincinnati appeared to be cruising, opening a 7-2 lead on a sacrifice fly by Ken Griffey Jr. in the sixth.
But Bubba Trammell sparked the Padres' rally with a pair of homers. He hit a solo shot off Scott Williamson to make it 7-3 in the seventh, then tied the contest with a two-run blast off closer Danny Graves in the ninth.
After Kevin Walker walked Adam Dunn and Austin Kearns with one out in the bottom of the ninth, the game was held up because of rain.
When it resumed, San Diego manager Bruce Bochy went to closer Trevor Hoffman, who got Sean Casey to fly to center before striking out Juan Castro swinging.
The Padres opened the scoring on Ryan Klesko's two-run homer off Brian Moehler in the top of the first, but Barry Larkin blasted a three-run shot off Bobby Jones in the third to put the Reds up, 3-2.
It was Larkin's seventh homer of the year and his first since July 21, a span of 13 games.
Kearns' two-run single gave the Reds a 5-2 lead in the fifth and Cincinnati stretched its advantage in the sixth on Walker's RBI single and Griffey's sacrifice fly.
