Daisy Pearce’s West Coast already face an uphill battle to make the AFLW finals after a five-goal haul from second-game forward Alannah Welsh lifted Gold Coast to a stunning 35-point win in Perth.

The Suns entered Saturday’s match featuring nine players who made their AFLW debuts last week, and their youthful exuberance proved hard to stop in the upset 10.9 (69) to 5.4 (34) win.

Welsh was the biggest star of the day, with the 18-year-old kicking 5.0 from 10 disposals in a dominant effort in attack.

“It’s awesome,” Welsh told Fox Footy after the match.
