Davis also won the 200 meters in 23.60 seconds and ran on the third-place 4x100 relay and fifth-place 4x400 relay.
Davis' Run U Xpress teammate Alexander Nunley of Garner turned in another impressive performance bagging three more national titles.
The current national 13-14 age group record holder in the 100-meter hurdles tied a 26-year-old meet record with a time of 12.94 to win his first of the day.
Later he won the 100-meter sprint at 11.23. Nunley had enough gas in the tank to best the field in the 200 meter final, racing home in 24.73.
