In men’s A-Grade water polo, second-placed Dolphins play heavyweights, the Octopuses as they return to Oasis after the summer break on Tuesday. Octopuses have won all but one game this season, and every game against the Dolphins. But the Dolphins have been closing the gap, turning a 11-4 loss in round one to a 10-7 round four loss and a 6-4 round seven loss. Meanwhile last-placed Raiders face the Dolphins development squad.
