MILWAUKEE -- Jonathan Lucroy hit a two-run, walk-off homer off Aroldis Chapman in the ninth inning as the Milwaukee Brewers beat the Cincinnati Reds, 7-6, Friday night at Miller Park.
Chapman (3-5) had converted his last six save opportunities, but he failed to hold a 6-5 lead in the ninth this time.
Khris Davis led off the ninth inning with a base hit against him. Lucroy then fouled off five straight pitches, including three consecutive 99-mph fastballs, before the Brewers' catcher sent a slider over the wall in left field for his first career walk-off home run.
Lucroy's homer put an exclamation point on a back-and-forth affair in which the lead changed hands three times in the final four innings.
Cincinnati's Todd Frazier homered and drove in four runs, part of a 3-for-3 day that also included a walk and a run scored. His RBI single in the seventh gave the Reds a late 6-5 lead.
Neither starter was particularly effective Friday.
Cincinnati starter Mike Leake went five innings and allowed four runs on nine hits and two walks. Alfredo Simon, Manny Parra and J.J. Hoover combined to hold the Brewers to a run on a hit through three innings before Chapman took over in the ninth.
After throwing seven scoreless innings his last time out, Tom Gorzelanny never got into a rhythm Friday against the Reds, loading the bases with two out in the first inning before Frazier started things off with a two-run single to put Cincinnati on the board.
Juan Francisco cut the lead to 2-1 in second with his 18th home run of the season. Milwaukee tied it on Lucroy's RBI single in the third and went ahead 4-2 later in the inning on Davis' two-run double.
Frazier homered on Gorzelanny's first pitch of the fourth to make it a 4-3 game, and Chris Heisey's two-run home run put Cincinnati ahead, 5-4, in the fifth inning.
Gorzelanny retired two of the next three batters before giving way to Donovan Hand, who worked out of the inning with no further damage.
NOTES: An MRI on the sprained right knee of Brewers center fielder Carlos Gomez revealed no structural damage. He's listed as day-to-day but is unlikely to return this weekend. ... Entering Friday, Cincinnati's Joey Votto and Shin-Soo Choo had combined to reach base safely in 217 of their 236 games this season. ... Brewers manager Ron Roenicke said he spoke with suspended outfielder Ryan Braun Friday but was not sure when Braun would return to Milwaukee to speak to the media about his suspension. ... Before Jean Segura's RBI single in the sixth inning, the Reds' bullpen went 17 1/3 innings without allowing a run, something Cincinnati manager Dusty Baker attributes to his starting rotation, which has thrown 46 2/3 innings over the last seven games. "That makes it so that guys aren't over-pitched," Baker said. "We can match up with who we want to versus who is the most rested."
