MILWAUKEE, WI (WHBL) - The Chicago Cubs pounded three homers Thursday afternoon, as they beat the Milwaukee Brewers 5-1 at Miller Park. Luis Valbuena, Nate Schierholtz, and Brian Bogusevic all went yard. The Brewers were out-hit 13-4, as they blew a chance to complete a first-ever four-game sweep of the Cubs. Kyle Lohse took the loss, giving up three runs on five innings. Lohse put much of the blame on plate umpire Chad Fairchild. Catcher Martin Maldonado said Fairchild told him that Lohse's "grumpy face" in giving up the Schierholz home run would cost him some strikes. Lohse said the umpire missed some strikes during that at-bat. In the ninth, Fairchild called Logan Schafer out on a low 3 and 2 pitch to end the game. Schafer threw down his bat and helmet in anger -- and he received an equipment violation from the umpire. The two exchanged heated words before Brewers' manager Ron Roenicke came out to break it up. Carlos Gomez provided Milwaukee's only offense with a solo homer. Lohse dropped to 10-10 with his loss. Jake Arrieta struck out five in seven innings to get the win, giving up just three hits. He retired 11 in a row at one point, as he improved to 3-2. The Cubs snapped a five-game losing streak, but the fourth-place Brewers extended their lead over last-place Chicago to four-and-a-half game games by taking 3 of 4 in the series. Milwaukee opens its final home series of the year tonight against Saint Louis. Right-hander Johnny Hellweg goes up against Cardinals' right-hander Shelby Miller.
