The pair played two games on the second day of the open men’s competition registering a win and a loss.
Facing American Samoa first up, the brothers pulled out all the stops to overcome their strong opponents in two tight sets won by the local lads.
Both stepped up their game from their previous day’s winning performance and once again got under the skin of their opponents with frustration seeing them make a number of unforced errors.
However in their second match of a seriously hot PNG day, the pair were caught on the back foot by the defending gold medalist pair from Tahiti.
The Tahitians wracked up the points early and forced the Cooks team to play a catch up game in what Brendan described as bad beach volleyball conditions.
He says the loss makes their journey to the podium that more difficult as they are likely to play top seeded PNG in cross play after pool play.
The local brothers are currently second in their pool and will take it one game at time as the tournament runs right up until Saturday before the closing ceremony of the Pacific Games.
