Starting in his usual position on the left flank, Porter switched with regular No1 Brad Scott to great effect as the Illawarra representative nursed a first-half rib injury after a collision with Dogs' five-eighth Alipate Noilea.

Porter's 26 points - three tries and seven goals - moved him to 126 points for the season, 24 clear of nearest rival Reece Jaeger from Thirroul.

Five-eighth Nathan Dureau also scored two tries and laid on two more with kicks to add to the Devils hefty tally after the Dogs scored the opening two tries of both halves only to be twice overwhelmed by a Wests' onslaught.

Wests' captain-coach Jason Ryles said his side will need to address their sluggish start to both halves as they face league leaders Helensburgh and Thirroul in consecutive weeks.

"I wouldn't say it was impressive but we got the job done in the end," Ryles said.

"At the end of the day we won the game but there's a few areas, in our defence especially, where we can improve.

"We need to be going set for set with teams, particularly going into the finals.

"We've got another two lead up games against the two best sides in the comp and we can work on that again."

Both sides were without several big names, particularly up front with Ryles, prop Greg Reh and back-rowers Brendan Oake and Danny Williams on the sidelines for Wests, while the Dogs were without star NSW Country back-rowers Blake Williamson and Jarrod Thompson.

Williams is unlikely to play again this season but Ryles expects Reh and Oake to return for the Devils' clash with Helensburgh in two weeks time.
