It was Burton's first win of the season and the 18th of his Nextel Cup career.
"I want to thank Richard (Childress) for believing in me," Burton said. "I felt like if we just kept putting ourselves in position we would have a chance and we've been doing a good job of that this year."
The win put Burton at top of the standings, six points ahead of Gordon (5,351-5,346).
Kenseth, despite falling to 10th place in the race, is only 18 points behind the leader.
