D'Angelo Jimenez led off the bottom of the 10th with a single against Lidge (4-3) and moved to second on a balk. After
Wily Mo Pena
struck out, Dunn - who had not driven in a run since July 30 against Colorado - sent Lidge's 1-1 offering over the wall in right field.
"I didn't get on top of my fastball," Lidge said. "I left it in a place where he could get it."
It was Dunn's career-high 27th home run.

The wild game saw Cincinnati take a 7-3 lead after scoring five runs in the seventh - four against reliever
- before Houston tied the contest in the top of the eighth.
"I haven't pitched in three days," Dotel said. "I'm better when I pitch every other day. It's kind of tough doing our thing and the hitters struggle. Today, they do it and we don't."
