ATLANTA - Tommy Hanson allowed one run in six innings, Dan Uggla and Chipper Jones came through in a four-run seventh, and the streaking Atlanta Braves defeated the Pittsburgh Pirates 6-1 Friday night.

The Braves won for the 13th time in 16 games after an 0-4 start - their worst since 1988.

Hanson (3-2) worked around six hits and three walks, his only blemish an RBI single by Garrett Jones in the fourth. Kris Medlen worked the final three innings, earning his first career save. Uggla and Jones drove in two runs apiece in the seventh to break open a 2-1 game.

A.J. Burnett (1-1) went six innings for the Pirates, pitching well but not enough to prevent his eighth loss in nine career decisions at Turner Field.
