ATLANTA -- Tim Hudson combined with three relievers for a five-hit shutout, Martin Prado hit a three-run homer, and the Atlanta Braves beat the San Diego Padres 6-0 on Tuesday night.
Hudson (12-4) allowed two hits and one walk in 6 2-3 innings and won his sixth straight decision.
After being held to five hits in a 4-1 loss to Eric Stults and the Padres on Monday night, the Braves had 10 hits, including Dan Uggla's 14th homer in the fifth inning.
The Braves began the day 5½ games behind first-place Washington in the NL East, their biggest deficit since trailing by 6 games on July 5.
Jonny Venters, Luis Avilan and Craig Kimbrel completed the shutout.
Yonder Alonso led off the ninth with a single off Kimbrel, but he was stranded at third base when Cameron Maybin took a called third strike to end the game.
Clayton Richard (9-12) left the game trailing 3-0 after giving up two hits in the seventh. Prado hit a 3-2 pitch from right-hander Brad Boxberger over the center field wall, pushing the lead to 6-0. It was Prado's sixth homer of the season and first since June 20.
Richard allowed five runs and nine hits in 6 1-3 innings. The Padres lost for only the third time in 11 games.
San Diego's only baserunner through four innings came on Chase Headley's first-inning walk. The Padres' first hit off Hudson was Mark Kotsay's single to left field to lead off the fifth. Hudson retired the next seven batters.
Hudson rebounded from his previous start when he gave up a season-high six runs in 4 1-3 innings of a no-decision at Philadelphia.
Richard, coming off 2-0 win over the Cubs, allowed up a run in the first. Michael Bourn led off with a triple and scored on Freddie Freeman's groundout.
Uggla's homer to lead off the fifth pushed the lead to 2-0. The Braves added a run in the sixth on three straight singles by Prado, Freeman and Chipper Jones.
Hudson was pulled after giving up a one-out single to Alonso in the seventh.
