MILWAUKEE (AP) -- Aaron Boone quickly turned a terrible day into an enjoyable one.
Sean Casey singled with one out in the 12th off Leo Estrella (2-2) and Boone followed with his 16th homer to left to give the Reds their third win in a row after losing eight straight. Boone had been 0-for-5 heading into the at-bat and had gone 115 at-bats since his last homer.
"To be sure, it was really great," Boone said, "In fact, it was awesome ... especially after going (hitless)."
His father, Cincinnati manager Bob Boone, jokingly said, "I thought he was 0-for-20."
Felix Heredia (5-0) was perfect through the final 2 1/3 innings for Cincinnati, which had its biggest comeback of the season.
Sexson's hit temporarily ruined a three-run rally by the Reds in the top of the ninth. After two one-out walks, Barry Larkin made the score 7-6 with an RBI single. After a double steal that put runners on second and third, D'Angelo Jimenez scored on a groundout by Jose Guillen. Casey then hit an RBI single to short left-center off reliever Mike DeJean that drove in Larkin and gave the Reds an 8-7 lead.
It was DeJean's seventh blown save in 24 opportunities. Scott Williamson, who came in for Cincinnati in the bottom of the ninth, blew his fifth save in 25 chances.
"I don't deserve to be the closer right now," De Jean said. "I'm not pitching well enough. Each position on this team is earned, and the only way to keep your job is to keep doing your job.
"The first half isn't all my fault, but I feel I've done my share to contribute. It's very frustrating."
Ken Griffey Jr., who had hit home runs in five straight games, came up as a pinch-hitter in the ninth and walked. According to the Elias Sports Bureau, the official statistician of major league baseball, Griffey's home run streak didn't end because he didn't have an official at-bat.
Brady Clark, getting a rare start in left field in place of All-Star Geoff Jenkins, doubled and scored in the first inning and hit a two-run homer in the third as the Brewers took a 7-1 lead after four.
"We were down early, and we could have just limped out of here," Aaron Boone said. "But we came to play. We took care of business, and now we need to build on this."
The Reds got within 7-4 on Casey's 10th home run of the season. His three-run shot, which hit the top of the fence and bounced over, came after Kinney had walked Jimenez and given up a single to Larkin.
"The three-run homer was huge," Brewers manager Ned Yost said. "That cut the deficit in half."
The Brewers scored in the first on back-to-back, two-out doubles by Clark and Sexson, who extended his hitting streak to 13 games.
Wes Helms hit his 16th home run leading off the second for a 2-0 Milwaukee lead.
Podsednik singled to start the third, extending his on-base streak to 43 games, longest in the majors this season. He scored on Clark's second homer of the season, the 20th allowed by Cincinnati right-hander Danny Graves in 20 games, including 19 starts.
John Vander Wal scored later in the inning when Boone threw a low ball to first that got past Casey.
Guillen put the Reds on the board with a solo homer in the fourth. Keith Ginter hit a two-run shot in the bottom of the inning that put Milwaukee up by six, but it wasn't enough.
"Do you believe in miracles?" Bob Boone asked. "That shows we still have our character. To come in here and sweep and now get three days off is great."
