LOS ANGELES — Chipper Jones singled home the go-ahead run in his final regular season at-bat at Dodger Stadium after Dan Uggla tied it with his second RBI single earlier in the ninth inning, and the Atlanta Braves defeated Los Angeles 4-2 Wednesday night. Dodgers closer Javy Guerra (1-3) lost for the third time in his last five apprarances after giving up five consecutive one-out hits in the ninth. The second one was a liner that ricocheted off his face, but manager Don Mattingly kept the right-hander in there and he surrendered RBI singles to Uggla, Jones and Jason Heyward.
