Gonzalez's three-run shot in the seventh tied his career high for homers in a game.
It was his 22nd of the season, tying Glenn Wright's franchise record for a shortstop (set in 1930 with the Brooklyn Dodgers) and one of his four hits in the game (matching his career-high).
Monday's win earned the Dodgers a split in the four-game series to complete the trip with a 4-3 record.
Bailey gave up a season-high six runs and nine hits, leaving after 59 pitches. Seager finished with four hits and three RBIs, while Chase Utley and Howie Kendrick each added three hits. "Right field's really short. I could have been 1 for 6 with a homer". Evan Longoria stopped the streak with a two-run homer off Matt Barnes in the ninth.
"It's tiny and the ball flies", Gonzalez said. He drove in another run with a groundout as the Dodgers scored 18 runs for the first time in 10 years.
Cincinnati Reds starting pitcher Homer Bailey sits in the dugout after being relieved in the third inning of a baseball game against the Los Angeles Dodgers, Monday, Aug. 22, 2016, in Cincinnati.
The seven home runs and four in one inning were also the most by a Dodgers team since September 18, 2006 - the game that featured four consecutive home runs in the bottom of the ninth inning by the Dodgers against the San Diego Padres. The left-hander said he has been "fighting through" issues in the right side of his neck "for years".
"A little stubborn", he said "I'm like, 'I can fight through and get it done.' That's just the competitor in me".
Stripling is the logical choice for Thursday, and Roberts said Tuesday that Bud Norris remains in the rotation, even after his bullpen appearance on Monday. LHP Rich Hill (blister) remains on track to be activated from the disabled list and start Wednesday against the Giants. He tied his career high with four hits and extended his hitting streak to 13 games. Jumbo Diaz came in and gave up a first-pitch home run to Gonzalez - the 24th time a Reds reliever allowed a homer to the first batter he faced. The seven homers allowed by Reds pitchers tied the club record.
Predictably, a position player - outfielder Tyler Holt - finished the game on the mound, the first for the Reds since Skip Schumaker on August 21, 2014, against Atlanta. He also hit three on April 8 of 2015 during his barrage that included five homers in the first three games of the season.
Dodgers: RF Josh Reddick was scratched from the lineup because of a jammed middle finger on his right hand that bothered his throwing. Reds SS Zack Cozart is improving but remains day-to-day with swelling in his left Achilles' tendon.
