ATLANTA -- Corey Hart hit a three-run double in Milwaukee's five-run seventh, Chris Narveson outpitched Tim Hudson and the Brewers beat the Atlanta Braves 6-3 on Saturday night. Prince Fielder hit his 21st homer in the Brewers' big seventh and was hit by a pitch in the eighth, leading to ejections for Braves reliever Jonny Venters and manager Bobby Cox. Venters threw a pitch over Fielder's head, then hit the stocky slugger on his back with his next offering. It was Cox's 156th ejection of his career, adding to his record, and third of the season. Matt Diaz and Eric Hinske homered for Atlanta. Narveson (8-6) allowed two runs and six hits in six innings. John Axford recorded the final four outs for his 11th save. Hudson (9-5) carried a 2-1 lead into the seventh inning but couldn't hold on for the win. Fielder led off with a drive to center on a 1-2 pitch. With two out, Rickie Weeks walked with the bases loaded to force in the tiebreaking run and Hart greeted reliever Peter Moylan with a bases-clearing double. Hudson allowed a season-high six runs in 62âÑ3 innings. He also gave up six hits and walked four, including three in the seventh. Plate umpire Angel Hernandez warned both benches after Venters' pitch over Fielder's head. Fielder threw his bat down and glared at Venters after he was plunked, and Hernandez put his arm around the first baseman and escorted him down the line. Cox rested left-handed hitters Jason Heyward and Brian McCann, and stocked his lineup with righties. The manager's strategy likely was influenced by lefty hitters' .204 batting average against Narveson, compared with right-handers' .335 average against the left-hander. Omar Infante started for Heyward in right field, David Ross was the fill-in catcher and Diaz, hitting only .218, opened in right field. Brooks Conrad played third for another switch-hitter, Chipper Jones, who was held out with a hamstring injury. Heyward had a pinch-hit single off Kameron Loe in the seventh. McCann struck out as a pinch hitter in the eighth. Jones lined out to left field as a pinch hitter in the ninth. Weeks scored on Fielder's double-play grounder in the fourth, giving Milwaukee a 1-0 lead, but the Braves responded in the bottom half. Alex Gonzalez hit a one-out single up the middle, giving the shortstop hits in each of his three games since he was acquired from Toronto on Wednesday. With two out, Diaz reached down to whip his bat around on a low pitch, sending his second homer of the season over the left-field wall. NOTES: All-Star RHP Yovani Gallardo is expected to come off the 15-day disabled list and start at Pittsburgh on Thursday. Manager Ken Macha said LHP Chris Capuano will come out of the bullpen to start Monday's series opener against the Pirates. ... Attendance was 48,174, a sellout.
