His first appearance in a major international championship was at the 1997 World Championships, where he competed in the long jump competition. He jumped 8.09, which still stands as his personal best.
Wignall's success in hurdling came relatively late. He took his first medal, a bronze medal, at the 2002 Commonwealth Games. At the 2004 World Indoor Championships, Wignall won the bronze medal in 60 m hurdles which is the distance used indoor. Later that year he competed in the Olympic 110 metres Hurdles where he placed fourth in the final, missing the bronze medal by one hundredth of a second. In the semi final he set a new national record with a time of 13.17.
In March 2006 he won the gold medal at the Commonwealth Games, with a time of 13.26, comfortably ahead of the rest of the field.
