The Milwaukee Brewers polished off a sweep of the Pittsburgh Pirates at Miller Park Sunday starting fast and holding off the Bucs 9-6.   The Crew jumped out to a 4-0 lead in the first inning thanks to Ryan Braun's three run homer and a solo shot from Casey McGehee.  Zack Greinke had a no hitter through the first four innings but the wheels came off in the 5th.  The Pirates touched him for five runs closing the lead to 6-5 but Jonathan Lucroy delivered a big, two out, two run homer in the bottom of the 5th to give Greinke his second win as a Brewer.  Milwaukee finished the home stand with a 5-1 record.  The Brewers (19-21) hit the road for a pair of two game series beginning in Los Angeles Monday night as Shaun Marcum faces Jon Garland at Dodger stadium.
