CHICAGO (AP) Adam Duvall's first swing with the Cincinnati Reds wasn't one to remember. He made up for it, though, with the rest of his inaugural at-bat.
Duvall and Eugenio Suarez hit two-run homers in a four-run sixth inning and the Reds took advantage of two late Chicago errors for a 13-6 victory over the Cubs on Monday night.
Duvall, who was called up from Triple-A earlier Monday, snapped a 5-5 tie with his pinch-hit homer off Cubs reliever Justin Grimm (2-4), who surrendered all four runs in one-third of an inning.
Grimm started the inning by walking Ivan DeJesus Jr. and then gave up the home run to Suarez that tied it.
The Reds, who entered Monday having lost five of their last six, used the rally to erase a two-run deficit. Duvall, who came to the Reds from San Francisco in a deadline deal in July, had 30 minor league homers this season.
''Any time you can ride that wave it's good,'' said Duvall, who admitted completely misreading the first pitch he saw from Grimm. ''A lot of games are won on big innings so any time you have a big inning like that - and obviously we had another one late to put the game away - it's good as a team.''
Cincinnati tackled on six unearned runs in the ninth off Chicago relievers Travis Wood and James Russell after second baseman Starlin Castro committed two of his three errors in the inning.
The big inning also included Reds closer Aroldis Chapman reaching on an error by Castro before scoring all the way from first on a two-run double by Jason Bourgeois.
''From an entertainment value standpoint, that had to be the game of the year,'' Reds manager Bryan Price said. ''It was an entertaining game, but I don't want a ton more like that. I like the win, but Geez Louise, there was some craziness to that.''
Ryan Mattheus (2-4) picked up the win in relief while Chapman pitched 1 2-3 innings to earn his 26th save in 28 chances.
Fresh off Jake Arrieta's nationally televised no-hitter against the Los Angeles Dodgers on Sunday night, the Cubs, who have lost five of six, took a 5-3 lead during a four-run fifth.
Addison Russell doubled in two runs before Kyle Schwarber followed with an RBI single and Kris Bryant delivered a two-out RBI single past two diving Cincinnati infielders. Russell had a solo home run in the ninth.
It wasn't enough, however, to combat the Reds two big innings.
''(It was) kind of a bad ending,'' Cubs manager Joe Maddon said. ''It didn't start too good, the middle part of the book was actually a pretty good read and then eventually it became a nasty ending.
''I'm over it already. Just throw that one away.''
The rally chased Cincinnati starter Michael Lorenzen, who was also called up from Triple-A on Monday. Lorenzen allowed five runs and six hits in 4 2-3 innings while walking one and striking out five.
The Reds built a 3-1 lead in the fifth when Brandon Phillips drove a two-out, two-run single past diving third baseman Tommy LaStella.
The go-ahead single came after Kyle Hendricks intentionally walked Joey Votto to get to Phillips.
Hendricks gave up three earned runs in five innings, scattering five hits while walking three and striking out four.
The Cubs took a 1-0 lead in the third on Dexter Fowler's solo homer into the basket in the corner in left field. The Reds tied it in the fourth on DeJesus' two-out RBI single, scoring Votto, who singled earlier in the inning.
When Chapman stepped to the plate in the ninth inning, Price told his closer just to take it easy. But when Chapman found himself at first base after reaching on an error and Bourgeois doubled into the corner, the lanky Chapman was off to the races. The sprint around the bases was more than Chapman bargained for. ''I'm tired,'' Chapman said through an interpreter. ''That's how it actually feels like. It feels like I was tired.''
Reds: OF Brennan Boesch (ankle contusion) was placed on the DL late Sunday. The Reds recalled Duvall on Monday from Triple-A Louisville to fill Boesch's roster spot. Boesch has been out since Aug. 23 when he fouled a pitch off his ankle.
Reds RHP Anthony DeSclafani (7-10, 3.84) will be trying to end a four-game skid that dates to Aug. 4, while Cubs RHP Dan Haren (8-9, 3.90) will be looking for his first win since Aug. 11, after losing two out of his last three starts.
