Joey Votto hit a three-run homer as the Reds piled up six runs in the third inning off Cueto, who got a warm welcome from his former teammates and fans before the game. It was Cueto's worst showing since he gave up eight runs during Kansas City's 11-8 loss at Toronto in the AL Championship Series last season.
The Reds' bullpen tied history while letting a 6-3 lead slip away.
Brandon Belt and Gregor Blanco singled in runs off J.C. Ramirez (0-2) in the seventh. Crawford connected off Drew Hayes for his third homer and an 8-6 lead.
