Bruce tied a career-high with five runs batted in during his eighth career multi-homer game while Drew Stubbs added two hits, a run scored, two stolen bases and a walk for the Reds, who have won two straight and 10 of 13 games overall since being swept by the Cardinals in three games two weeks ago.
Cueto (12-4) allowed six hits, did not walk a batter and fanned eight in helping Cincinnati push its lead over St. Louis in the NL Central to 4 1/2 games. Sam LeCure retired the side in order in the ninth to preserve the Reds’ 11th win in 14 meetings with Chicago this season.
Tom Gorzelanny (7-8) was saddled with the loss after allowing a season-high six runs on seven hits and a pair of walks with only one strikeout in five innings for the Cubs, who had a three-game win streak halted.
