CHICAGO (AP) - Adam Dunn reached 100 RBIs for the first time with his 44th home run, and the Cincinnati Reds beat the Cubs 8-3 on Tuesday night - a loss that could be costly for Chicago in the NL wild-card race.

Chicago began the day just a game ahead of San Francisco, which played late in San Diego. Houston, which was 1 1/2 games back, was playing St. Louis.

D'Angelo Jimenez and Darren Bragg also connected off Greg Maddux (15-11), who lost his second straight start to the Reds.

Josh Hancock (5-2) drove in a run and finally got a win after being the victim of blown saves in his previous two starts. He gave up two earned runs and scattered seven hits over eight innings, striking out three and walking two.

Corey Patterson drove in a pair of runs with a triple, but the Cubs managed only six other hits.

Maddux has struggled all year against the Reds, and Tuesday night was no different. He gave up six runs - all on the three homers - and six hits in five innings. He also plunked two batters in the same inning for only the second time in his career - both this year.

Who was the other team he left black-and-blue? The Reds on April 7, the four-time Cy Young Award winner's first start with his original team after 11 years in Atlanta. And just as they did in April, the Reds made Maddux pay for the errant throws.

After Maddux plunked Felipe Lopez to start the third, Jimenez followed with a homer that just cleared the fence in right field. Maddux hit his next batter, Sean Casey, in the leg. Two batters later, Bragg homered into the bushes in center, giving Cincinnati a 4-0 lead.

Maddux got in more trouble in the fifth with a leadoff walk to Casey. Dunn followed by putting a 3-2 pitch into the stands in right-center for a two-run homer, giving him 100 RBIs.

Patterson finally ended Hancock's bid for a shutout in the fifth, driving in two runs with a triple into the corner in deep right.

Notes: Maddux is 1-3 with a 6.75 ERA against the Reds in five starts this season. … Reds hitters have been hit by a pitch 80 times this season, a club record.

… With a crowd of 38,895 on Tuesday night, the Cubs have drawn a team-record 2,977,803 this year. They are expected to top the 3 million mark Wednesday.
