MILWAUKEE, WI (WHBL) - Jonathan Lucroy hit a walk-off homer to give the Milwaukee Brewers a 4-3 home win over Cincinnati Tuesday night. The Brewers extended their National League Central lead to a game-and-a-half over Saint Louis - their biggest margin in almost two weeks, after the Cardinals fell to Tampa Bay. The fourth-place Reds dropped to four-and-a-half back, going 0-5 since the All-Star break. The Brewers scored all their runs on solo shots. Lucroy hit a pair, including the game-winner off Sam LeCure, which led off the bottom of the ninth. Ryan Braun and Aramis Ramirez hit back-to-back homers in the first frame. It extended Braun's hitting streak to ten games. Francisco Rodriguez got the win in relief. He's now 4-3. There was a tense moment in the ninth when K-Rod hit Kristopher Negron in the helmet with a pick-off throw. Negron was given medical attention, but he stayed in the game. LeCure took the loss. He's 1-2. Jay Bruce ended an 0 for 16 slump with an R-B-I double for Cincinnati. Reds' starter Homer Bailey retired 11 in a row at one point. Brewers' starter Jimmy Nelson ran out of gas in the seventh, hitting a couple batters before Chris Heisey hit a sacrifice fly off reliever Brandon Kintzler to tie the game. Milwaukee second baseman Scooter Gennett left after four innings with recurring tightness in a right quad muscle. Milwaukee will go for a sweep of the Reds this afternoon. Right-hander Kyle Lohse starts against Reds' righty Mike Leake. Pregame coverage gets underway on WHBL at 12:35.
