Final Score: Atlanta 8 - Chicago Cubs 5 Chicago, IL (Sports Network) - Jeff Francoeur was 2-for-5 with three RBI as Atlanta topped Chicago, 8-5, in the opener of a three-game weekend set at Wrigley Field. But the real story of the game was a fight between Cubs teammates Michael Barrett and Carlos Zambrano. After seeing the Braves take a 7-1 lead courtesy of a five-run fifth inning helped by Barrett's passed ball and throwing error, both players engaged in a heated argument in the dugout prior to the bottom of the inning. Zambrano and Barrett came together and attempted to throw punches before both players were restrained and separated from each other, and neither player returned to the lineup. Koyie Hill took Barrett's spot at catcher, while Scott Eyre took the mound for the sixth. "These things shouldn't happen among teammates," said Cubs manager Lou Piniella on the fracas. "Go fight the other team if you have to. It's something that shouldn't happen to a team. But it did happen." Barrett was later taken to Northwestern Memorial Hospital to have a cut lip examined, suffered when he scuffled with Zambrano a second time in the Cubs' clubhouse. Both players will be disciplined after a meeting with Piniella on Saturday. Brian McCann had two hits, a run scored and one driven in for the Braves, who have won three of four and set a season-high for hits in a game with 20. Kelly Johnson hit safely three times with an RBI and a run scored, Edgar Renteria collected three hits and scored twice, and Pete Orr was 2-for-3 with two runs scored. Kyle Davies (3-3) scattered six hits and one run over seven innings, also helping his cause with three hits and a run-scoring double. Derrek Lee finished 3-for-3 with a home run and two runs batted in for the Cubs, who have dropped five straight. Aramis Ramirez hit a two-run homer and Jacque Jones added a solo shot. Zambrano (5-5) was torched for 13 hits and seven runs -- six earned -- in five full innings, a very rough game for him on his 26th birthday. "You don't like to see some of the silliness that's going on the field," said an increasingly frustrated Piniella. "I only have so many players that I can play. It's about time some of them start playing like major-leaguers or get somebody else in here that can catch a damn ball or run the bases properly." With the game at 2-1 after four innings, Atlanta blew the contest open with a five-spot in the fifth. Francoeur drove home two with a one-out double to make it 4-1. Alfonso Soriano prevented a potential third Braves run when he cut down Francoeur at home on Orr's single, but the third run did score on a Barrett passed ball and throwing error with Davies at the plate that allowed Scott Thorman to come home. "I don't know where we are right now, we're a bad team right now," Piniella continued about his team's disappointing play. "We're doing stuff you don't even see, like dropping fly balls. It's really inexcusable." Davies then stroked double off the wall in right-center to drive in Orr, and Johnson's double to right scored Davies for a 7-1 game. Willie Harris flied out to end the inning, but the real fireworks happened in the Cubs dugout afterward. Francoeur added an RBI single in the sixth to boost the Braves' lead to 8-1, then the Cubs tacked on three in the eighth on Lee's sacrifice fly and a two- run shot by Ramirez. Jones made it 8-5 off Bob Wickman with a one-out opposite-field solo homer in the ninth. Although pinch-hitter Angel Pagan reached with a bunt single, Wickman induced Cesar Izturis into a game-ending double play. The Braves picked up a run in the first, as McCann's two-out RBI single scored Johnson. It was a 2-0 game in the fourth when Johnson's routine fly to right with two outs was dropped by Matt Murton, who might have had trouble tracking the ball in the sun. Orr, who was at third base after reaching with a single, came home on the miscue. Lee cut the Cubs' deficit in half with a leadoff blast in the bottom of the frame.
