The Panthers have kept their undefeated streak alive in the NRL with an 18-4 win over a much-improved Titans outfit yesterday.

They are the first team in the premiership history to go 8-0 in consecutive seasons but it was far from a pretty win with the Titans putting the heavyweights under the pump.

Meanwhile, the Rabbitohs have beaten a plucky Manly outfit 40-22 on the back of a masterclass from Cody Walker in his 150th match.
