The biggest competition that he has won was the vert contest at the 2001 X-Games. Before his final run- the last run of the event- Burnquist was sitting in second place behind two-time defending champion Bucky Lasek. He produced a flawless run, including multiple tricks that had never been seen before, and as a result, were unnamed. During the run, commentator Tony Hawk went hoarse and nearly lost his voice while screaming in disbelief. He was rewarded with a 98, the highest score ever given in any X-Games skateboarding event.
Burnquist's speciality is switch stance skateboarding. He has always tried to find new ways to make his tricks more creative and more difficult. He has a signature trick called "one-footed smith grind". He has also been featured in the hit video game, Tony Hawk's Pro Skater, and appeared in every game in main series up to Tony Hawk's Proving Ground, with the exception of Tony Hawk's Pro Skater 3, due to a result of his appearance in another skateboarding game, ESPN X Games Skateboarding, during that year.
