San Francisco jumped out to a 3-1 lead, but couldn’t hold it at Miller Park Wednesday night. Home runs by Jonathan Villar and Domingo Santana powered Milwaukee’s comeback in a 6-3 decision that kept the Brewers in first place in the National League Central Division.  Jimmy Nelson got the victory by going six innings, allowing three runs, a walk and seven hits.  He’s now 4-3.  Villar, Santana and Jesus Aguilar all had two hits apiece.  The Brewers try to take three out of the four-game series this afternoon at 1:10 p-m.  Rookie Paolo Espino is expected to be brought up from the minors to take the start.
