The 28-year-old dominated the competition, winning every heat to earn his first championship in the world's most prestigious freestyle motocross series. Spain's Dany Torres finished strong in second for the day, with Adam Jones from the United States earning his first podium of the season in third.

Sheehan has been charging in recent events, closing the gap on New Zealand's Levi Sherwood.

After winning the first two events of 2014, Sherwood sat at the top of the leaderboard, however an ankle injury sustained in Qualifying at the weekend prevented him from moving beyond the first round of the Final.

Sheehan could have taken it easy from that point on, but he gave everything he had put on a real show for the massive crowd.

In douing so he defeated every opponent, including Dany Torres, with spectacular tricks like the double backflip and the Flair.

When the final World Tour standings were tallied, it was an emotional Sheehan in first, Sherwood in second, and Torres in third. Each now has one World Tour title under his belt.

"I've been wanting this for years, and it's a dream come true. I'm on top of the world.” said an extatic Sheehan.
