Mays burst through a hole at the line of scrimmage and, suddenly, was racing alone down the sideline. He got caught at the Zip 10 but, one play later, Myers hit Brandon Swindall on a 9-yard touchdown pass to make it 10-7.
The 61-yard run was the longest of Mays' career at Utah State.
"We just started changing up a little bit more on the perimeter with him," Aggie coach Matt Wells said. "We weren't having much luck moving those big bodies around inside and we had more success on the edge."
Utah State finished the first quarter with minus-five yards of offense.
