PITTSBURGH (AP) – Yovani Gallardo gave up just two hits over 6 2-3 innings and the surging Milwaukee Brewers dropped the weary Pittsburgh Pirates 6-0 on Tuesday night.  Gallardo (16-8) struck out six and walked four to win his eighth straight decision as Milwaukee moved in front of fading Pittsburgh in the jumbled National League wild-card race. The teams entered the day 2 1-2 games back of the Cardinals, who played Houston later.  Ryan Braun had two hits, drove in a run and stole three bases for the Brewers, who have won six of seven. Milwaukee’s seven stolen bases were the most by the franchise since it moved to the National League in 1998. Carlos Gomez and Jonathan Lucroy had three hits apiece for the Brewers.  A.J. Burnett (15-8) gave up two runs in six innings but couldn’t stop Pittsburgh’s late season swoon. The Pirates are 4-12 this month.
