Day One of the 2013 Billabong Pipe Masters

Low seeds battle it out for a place with the big guns at near-perfect Backdoor and Pipeline.

The Billabong Pipe Masters is well and truly rolling. Opening day was as filled with as much action and drama as you could possibly hope for. With the duel heat format, whereby two heats are run simultaneously and overlap, it means that the four men in the water are battling for sets and throwing everything they've got at the world's most famous split peak. Backdoor fired and Pipe showed odd moments of brilliance, and nothing went unridden. Two full rounds were completed, and there were some big moments.

Standout of the day: Well, uh, Sebastian 'Seabass' Zietz stormed through the deepest Backdoor barrel you could hope to see for the event's first (and today's only) perfect 10-point ride. With that in mind, it's hard to look past last year's Triple Crown champ.

Honourable Mention: Ryan Callinan, who fell to Seabass in round two, had a blistering performance in round one. In his first ever heat in a world tour event (as a Billabong wildcard), Ryan relentlessly dropped into Backdoor bombs on his backside and stormed out of two particularly big ones – enough to combo the one and only Dane Reynolds.

What to watch for: Mick Fanning and Kelly Slater hit the water in the next round. With Kelly needing to win the event with Mick third or worse to swoop the title from beneath White Lightning, all eyes will be on the Floridian and the Gold Coaster to see who has the most grit. Don't miss a second of it.
