University of Florida's Tony McQuay won the men’s 400-meter dash at the U.S. outdoor championships Saturday, blowing past former Olympic and world champion Jeremy Wariner over the final 100 meters.

The victory over Wariner had McQuay making bold predictions for the world championships, Aug. 27 to Sept. 4 in Daegu, South Korea, ready to break Michael Johnson's nearly 12-year-old record.

“I want to break the world record. I’ve got my mind set on that,” he said.

Johnson’s record is 43.18 seconds, while McQuay has a ways to go, finishing well behind at 44.68.
