Marco Estrada fired six shutout innings and Jonathan Lucroy backed him with a pair of RBI Tuesday in the Milwaukee Brewers\' 5-2 win over the Chicago Cubs. Estrada (1-5) notched his first victory in his 16th start of the year, baffling the Cubs on two hits. The right-hander struck out nine and walked one. John Axford was called in to log his 19th save after the Cubs scored a two runs in the ninth and the Brewers clinched their three-game set. Lucroy\'s two-run double in the sixth put Milwaukee ahead 4-0. Corey Hart and Carlos Gomez each drove in a run for the Brewers. Chris Rusin (0-1) absorbed a hard-luck loss in his first major-league appearance for the Cubs, surrendering just one run on one hit over five frames. Alfonso Soriano and Starlin Castro drove in the ninth-inning runs for Chicago.
