Nyjah Huston of the United States is the favourite to top the podium, with 16 street skateboarding medals to his name in the X Games.

DUTCH DUO UNPRECEDENTED DOUBLE
Anna van der Breggen and Marianne Vos have already won Olympic gold medals and they will go in search of a second in the women's road race.
No female cyclist has won the event twice, but the 2012 champion Vos and defending champion Van der Breggen will start the course at Musashinonomori Park looking to achieve that feat.
EYES ON THE POOL – AND ON THE BEACH
The first swimming medals of the Games will be handed out on Sunday following Saturday's heats.
There is an open field in the men's 400 metre medley final – the first event of the day – after home favourite Daiya Seto failed to qualify.

Meanwhile, Australia will take to the pool confident of another gold in the 4 x 100m freestyle relay final, boasting the title, the world record and by far the best qualifying time.
A new water sport should garner some attention, though, as surfing makes its Olympics bow.
Tsurigasaki Surfing Beach – preferred to a wave pool – plays host for the first and second rounds on Sunday.
