Australia's Julian Wilson is through to the quarter-finals at the Corona Open J-Bay event in South Africa, while Joel Parkinson has bowed out after the fourth round.
World No.1 Wilson took out his fourth round heat with a total of 13.66, ahead of countryman Wade Carmichael (13) and Portugal's now-eliminated Frederico Morais (12.90).
Parkinson's heat against stars Jordy Smith and Conner Coffin came down to back-up scores, leaving Coffin finishing first with a 16.03 two-wave total.
It was the Australian's last time at J-Bay after announcing he will retire in December, and said he will miss having priority at a Jeffreys Bay wave.
"That is probably the only thing I will miss about being on tour, there are a lot of other cool things I suppose," the two-time event winner said.
"But, that one thing is the thing that probably drives you to want to be on the pro tour - to have priority and have the line-up to yourself.
"I know it is fresh, a loss, but I feel like I've won."
Australian Owen Wright withdrew from the event during round three due to a severe cold, leaving Hawaii's Sebastian Zietz to cruise through to the fourth round.
Zietz finished second behind 2017 J-Bay winner Filipe Toledo, who surfed a near-perfect 9.5 wave and finished the heat on top with a 17.23 two-wave total.
Japan's Kanoa Igarashi took the highest heat total in the event so far, with 18.04 out of a possible 20.
The final eight are: Conner Coffin (USA), Wade Carmichael (AUS), Julian Wilson (AUS), Jordy Smith (ZAF), Filipe Toledo (BRA), Gabriel Medina (BRA), Kanoa Igarashi (JPN), Sebastian Zietz (HAW)
