CINCINNATI -- Cincinnati outfielder Jay Bruce went 3-for-5 with a homer, two doubles, and two RBI to lead the Reds' 14-hit outburst in a 13-7 victory over the Milwaukee Brewers on a wild afternoon before 41,678 fans at Great American Ball Park.
Bruce hit his third homer for Cincinnati in the second inning. Jean Segura went 4-for-5 with a double and homer for Milwaukee, and Norichika Aoki also homered.
Cincinnati (21-16) went 8-for-14 with runners in scoring position and collected six extra-base hits.
Milwaukee (15-19) had 11 hits but was unable to cash in on its scoring opportunities, going 2-for-9 with runners in scoring position.
Reds right-hander Mat Latos (4-0) picked a good day for his worst outing of the season. He allowed seven runs, six earned, on nine hits in six innings. He walked three and fanned four. But Cincinnati's offense picked him up, and he helped himself by going 2-for-3 with two RBI.
Brewers starter Hiram Burgos (1-1) wasn't so fortunate -- giving up 12 runs, 10 earned, in just three innings. He gave up 11 hits and walked three.
Four Brewers relievers combined to allow just one run on three hits over the final five innings.
In his previous three starts, Latos had been 3-0 with a 1.50 ERA, having allowed just three earned runs in 18 innings. But the Brewers roughed him up Saturday.
Segura hit an opposite-field home run on a 1-0 pitch from Latos in the first inning, putting the Brewers ahead 1-0. Later in the inning, Aramis Ramirez doubled off the left-field wall, driving home Ryan Braun with Milwaukee's second run.
Bruce launched a 1-1 pitch from Burgos 437 feet to right-center field, making the score 2-1 in the second. From there, things unraveled quickly for the Brewers.
Todd Frazier reached on a bunt single. Then Braun dropped Xavier Paul's routine fly, putting runners at second and third. Devin Mesoraco walked, loading the bases with nobody out.
Latos' RBI single tied the score 2-2. Shin-Soo Choo's bases-loaded walk, Zack Cozart's sacrifice fly and an RBI groundout by Joey Votto put Cincinnati ahead 5-2.
Milwaukee scored twice in the third, on an RBI double by Braun and RBI single by Ramirez.
But Cincinnati erupted for seven runs in the bottom half, including an RBI double by Bruce, who had two doubles, a homer and two RBI in his first three at-bats.
Frazier, Mesoraco and Choo contributed RBI doubles in the third, putting the Reds ahead 12-4.
Gomez's two-run single in the fifth made the score 12-6.
Aoki hit a solo homer off Latos in the sixth, his fourth homer this season, but Milwaukee couldn't get closer.
NOTES: Aoki struck out for the first time in 37 plate appearances when he fanned in his first at-bat. .. In the third inning, Bruce became the first Reds player to collect two hits in an inning since Drew Stubbs on April 25, 2011, at Milwaukee, and he became the first Red to double twice in an inning since Sean Casey on Aug. 7, 1998, vs. the Brewers. .. Cincinnati scored 11 or more runs for the fifth time this season. ... Burgos became just the fourth Milwaukee pitcher to allow 12 runs. The last to do it was Randy Wolf, on July 21, 2010, vs. Pittsburgh. ... It was managerial victory No. 1,602 for Dusty Baker, tying him with Hall of Famer Fred Clarke for 17th place all-time.
