The most decorated track athlete in ECU history, Irvin was a six-time All-America selection. Irvin earned All-America status in the 400 meters in 1990, '91, and '92 while setting the school-record (45.32) in the event at the '92 NCAA Outdoor Championships. A four-year letterman (1989-92), Irvin set six track records during his career with his mark in the 400 meters still standing as the top time in ECU history. He helped the U.S. capture the gold medal at the 1991 World University Games as a member of the 4x400m relay team. He earned a first-place finish in the 400m at both the indoor and outdoor IC4A Championships in '92.
