Brewers 6, Reds 5: Sean Halton hit a walk-off solo homer with one out in the bottom of the ninth as host Milwaukee rallied past Cincinnati.

After Jim Henderson (4-5) worked a scoreless top of the ninth, Zach Duke (1-2) retired Logan Schafer on a groundout to open the bottom half. However, Halton lifted a 1-0 changeup over the fence in center field to reduce Cincinnati’s lead over Washington in the race for the second National League wild-card spot to 4 1/2 games.

Jean Segura had two hits and drove in a pair of runs to key the Brewers’ comeback. Todd Frazier, Jay Bruce, Brandon Phillips and Joey Votto each recorded two hits to account for all eight by the Reds, who fell 3 1/2 games behind NL Central co-leaders Pittsburgh and St. Louis.

Cincinnati struck for three runs as its first five hitters reached base against Yovani Gallardo, a surge highlighted by an RBI single by Votto and a bases-loaded walk to Ryan Ludwick. Zack Cozart delivered a sacrifice fly to left to cap the inning before Frazier singled home a run in the third and homered in the sixth to stake the Reds to a 5-1 lead.

Milwaukee plated a run on a fielder’s choice in the seventh but rallied to tie it an inning later on Segura’s two-run triple - his NL-leading 10th of the season - and Jonathan Lucroy’s sacrifice fly.
