Gold Coast forward Ben King has kicked a career-high six goals but defender Charlie Ballard suffered a potential season-ending knee injury in the Suns' crushing 87-point win over West Coast at Optus Stadium.
The Suns kicked nine unanswered goals from midway through the first quarter to early in the third on the way to the 20.16 (136) to 7.7 (49) triumph in Perth on Sunday.
It marked the biggest win in Gold Coast's history, bettering their 86-point triumph over Hawthorn in 2017.
But there are fears Ballard may have torn the anterior cruciate ligament in his left knee after a jarring landing soon before half-time.
"He'll go for a scan first thing (on Monday) I would say," Gold Coast coach Damien Hardwick said.
"I don't know what the prognosis is.
"I'd just rather wait and we'll get the scan results, because we need him.
"He's such an important player for us. Great locker room guy, glue guy as well. So we've got our fingers crossed that everything's OK."
West Coast's midfield barely got going, with players including Tim Kelly (14 disposals) and Harley Reid (12 disposals) well below their best.
Suns ruckman Jarrod Witts (68 hitouts) had a field day against Eagles big man Matt Flynn (13 hitouts).
King kicked 6.2 and produced a mark-of-the-year contender when he leapt onto the shoulders of Eagles defender Harry Edwards and stayed there for a couple of seconds to reel in a spectacular third-quarter grab.
Ben Long kicked four goals while Jake Rogers (three goals) and Ethan Read (two goals) showed plenty of promise.
Noah Anderson (36 disposals, nine clearances, 713m gained), Matt Rowell (30 disposals, 10 clearances) and Touk Miller (26 disposals, 10 clearances) ran rampant, while former Tiger Daniel Rioli tallied 21 disposals and two goals in his Suns debut.
Andrew McQualter, in his first year as Eagles coach, promised to implement a fast-paced, exciting brand of football at West Coast.
But with the Eagles soundly beaten in the midfield, there was barely a chance for the home side to show any sort of identity.

West Coast were thrashed in the contested possession count (145-102), inside 50s (67-34) and clearances (50-33) on a woeful day.
"Gold Coast were really sharp, but we're bitterly disappointed," McQualter said.
"We expected better. Unfortunately, we didn't get it right.
"When you go minus 40 in the contest, you're just not going to be able to compete."
McQualter said Jake Waterman, who was subbed out in the third term to ice a calf niggle he battled in the lead-up to the game, was taken out of the match merely as a precaution.
Gold Coast's losing streak on the road extended to a club-record 16 games at one point late last season.
But their win in Perth means the 'away hoodoo' is off their shoulders early as Gold Coast target a maiden finals appearance in 2025.
Eagles gun Reid tallied just four first-half disposals and cut a frustrated figure amidst tight attention from Gold Coast players, often engaging in wrestles or playing for free kicks.
The 19-year-old kicked a beautiful 50m goal in open play in the third term, but it was a rare highlight for the Eagles as the Suns continued to assert their dominance.
King's spectacular third-quarter mark was admired by the 46,532-crowd - despite him being part of the opposition.
