Braves 6, Pirates 1: Dan Uggla and Chipper Jones each drove in a pair of runs in a four-run seventh to power host Atlanta to its third straight victory.

Tommy Hanson (3-2) allowed one run on six hits in six innings, striking out five and walking three as the Braves matched their best home start (6-1) since 1997 - the year Turner Field opened.

Martin Prado and rookie Tyler Pastornicky contributed RBI singles for Atlanta, which has gone 13-3 since an 0-4 start.

Pirates starter A.J. Burnett (1-1) gave up two runs on six hits in six innings while making his second start. He struck out eight and walked three.

The Braves broke the game open against Pittsburgh's bullpen in the seventh. Tony Watson loaded the bases on a single to Prado and a pair of walks, bringing on Evan Meek.

Uggla greeted Meek with a two-run double and Jones followed with a two-run single to extend the lead to 6-1.

Garrett Jones singled in the lone run for Pittsburgh, which has been limited to two runs or fewer 13 times in 19 games.
