Chris Hawkins saw the fumble, scooped up the loose ball and took off running.
The USC safety quickly surveyed 94 yards of open field in front of him, mentally noting the Arizona State players chasing him from behind.
Hawkins called on his "track days" and told himself to "run with form" as he dashed for a touchdown.
"Everybody tells me I probably should have looked at myself on the big [video] board," Hawkins said, "But I wasn't. I was just making sure I got to the end zone."
Hawkins' play stymied a potential Arizona State rally, set the stage for another turnover, and sent the Trojans on their way to an important 42-14 road victory.
