On a gloriously sunny day in Vail, two slopestyle veterans topped the rankings to cement a strong claim for the 2017 Burton US Open slopestyle title.

With so many world-class riders in attendance, it was always going to be just as interesting to see who didn't get through as who did. Despite a history that suggests he might be half-man, half-slopestyle course, Max Parrot couldn't get his run together and failed to make the cut. Neither could Yuki Kadono, who won in 2015 with a run that included back-to-back triple cork 1620s.

As for Hailey Langland, the top part of her run was one of the finest we'd seen in years. The 16-year-old threw herself from rail to rail, and added shiftys to her spins, but it didn't add up to a completed run meaning she's out too.

And if you were wondering what Eric Beauchemin had brought from his fancy dress cupboard for the finals, you'll have to wait another year. The Artist Formerly Known As Michelangelo crashed out hard.

Leave it to Jamie Anderson to set the pace once again. Without needing to dig in her trick bag for a 1080, or a 900, or even a 720 for that matter - her style put her out in front ahead of Anna Gasser and Spencer O'Brien. When her safety run gets her the top qualifying spot, it's fair to say she's still the one to beat.

Despite seemingly treating the semis like a final of its own, Mark McMorris couldn't regain the lead from Sven Thorgren on his second run. The Swede edged McLovin's first attempt by less than a point, thanks to a run that included some solid dub 1080s and a fully extended backside rodeo nosegrab for the ages.

Halfpipe semis kick off tonight at 6pm CET - follow all the action on the Burton US Open livestream.
