Peel Thunder crushed the West Coast Eagles by 98-points at Lane Group Stadium on Saturday.
The Thunder dominated the entire match, restricting the Eagles to just five goals in the 19.18 (132) to 5.4 (34) victory.
Veteran Blair Bell was instrumental in the win booting four goals.
"The mayor of Mandurah, just doing his thing," Coach Geoff Valentine said.
"He was a real force in our forward line on the weekend."
Fremantle-listed defender Heath Chapman suffered a dislocated shoulder in the clash, a massive blow for the young gun who has missed a large part of the season with hamstring and calf injuries.
"That took a little bit of an edge off the day but unfortunately that's footy sometimes," Valentine said.
The win has bumped the Thunder up into fourth on the WAFL ladder with three games remaining in the regular season.
