In-form young Brazilian Gabriel Medina, Kelly Slater and Joel Parkinson have all moved into the quarter-finals of the ASP tour event at Margaret River.

Gabriel Medina has marked himself as the one to beat at the men’s world surfing tour event at Margaret River after the Brazilian cruised into the quarter-finals on Thursday.

Following his title victory in the season-opening round on the Gold Coast last month, the 20-year-old was clinical in his round-four heat against local West Australian wildcard Yadin Nicol and Miguel Pupo.

Medina went straight through to the last eight with an impressive score of 14.33 in the 1.5-metre waves at Main Break.

He’ll next face Australian Josh Kerr, who outclassed Nicol in round five, which was held in the neighbouring break of The Box.

American legend Kelly Slater also took the easy way into the quarter-finals where he’ll meet fellow veteran, Australia’s 2012 world champion Joel Parkinson.

Parkinson celebrated his 33rd birthday with a strong win over Brazil’s Filipe Toledo after a below-par outing in round four when he finished below American Nat Young and Brazilian Adriano De Souza.

In-form Queenslander Bede Durbidge will take on South African Jordy Smith and Young will battle Tahiti’s Michel Bourez in the other quarter-finals.
