Phoenix, AZ (Sports Network) - Martin Prado went 4-for-4 with the eventual game-winning RBI in the seventh inning as the Arizona Diamondbacks edged the San Diego Padres, 6-5, to win the rubber match of a three-game set at Chase Field.

Eric Chavez had a two-run homer while Gerardo Parra, Miguel Montero and Patrick Corbin each added an RBI as well.

Corbin (8-0) allowed a season-high four runs (three earned) but still earned the win. He scattered seven hits, fanned five and walked two over six frames en route to becoming the first Diamondbacks pitcher to start the season 8-0 since Micah Owings in 2011.

Carlos Quentin and Kyle Blanks each went 2-for-4 with two RBI for the Padres, who have dropped four of five.
