CINCINNATI (AP) -- Taylor Teagarden singled home the tiebreaking run off Aroldis Chapman with two outs in the ninth inning Wednesday night, completing the Chicago Cubs' biggest comeback of the season for a 6-5 victory and a doubleheader split with the Cincinnati Reds.
Cincinnati won the opener 9-1 behind another strong showing by Mike Leake, who could be traded this month.
The Cubs overcame a five-run deficit to get the split, completed with Teagarden's pinch-hit single off Chapman (3-4). Hector Rondon (4-2) escaped a bases-loaded threat in the eighth, and Jason Motte finished it for his sixth save in as many chances.
Leake (8-5) went eight innings in the opener to beat the Cubs for the fifth straight time. Todd Frazier extended his post-home run derby surge with three more hits, including a two-run double in the first inning off Kyle Hendricks (4-5).
Cubs catcher Kyle Schwarber, who grew up in nearby Middletown, Ohio, went 7 for 16 in the series with an RBI double, two homers and a stolen base.
Both teams had 10-batter, five-run rallies in the nightcap.
The Reds piled up their five in the second inning against Dallas Beeler, who didn't make it past the inning. Shortstop Starlin Castro booted a potential double-play grounder to extend the rally, and Billy Hamilton doubled home two runs.
The Cubs got their five runs in the top of the third off left-hander Tony Cingrani, who failed to make it out of the inning. Chris Denorfia doubled home two runs, and Kris Bryant tied it with a pinch-hit, two-run single.
The Reds got the bulk of their runs from big innings. Twice in the opener, they sent nine batters to the plate to score four runs.
OUTTA HERE
Cubs manager Joe Maddon was ejected in the fourth inning by first base umpire Adam Hamari for arguing a balk call. It was his third ejection of the season.
TRAINER'S ROOM
Cubs: CF Dexter Fowler jammed his right hand on the wall in center while catching Frazier's fly ball in the fourth. He repeatedly flexed his hand but stayed in the game.
Reds: Cingrani was activated off the DL. He had been sidelined since June 15 with a strained pitching shoulder.
UP NEXT
Cubs: After a day off, the Cubs return to Wrigley Field to start a series against the Phillies. Jon Lester (5-8) faces Jerome Williams (3-7).
Reds: They're off on Thursday as well before going to Colorado for a series. Anthony DeSclafani (5-7) faces Eddie Butler (3-6) in the opener.
