Sam Whiteman says his present-day Western Australian champions deserve to be rated as one of the state's greatest-ever sides after their Sheffield Shield three-peat.

WA extended their domestic dynasty by sealing their third successive Shield and 18th in their history with a 377-run annihilation of Tasmania in the final at the WACA in Perth.

Whiteman was named player of the match for his first-innings of 104 — his second ton in a Shield final after also scoring 123 in the 2021/22 decider.

He also became the fourth man to captain WA to two Shield titles, after John Inverarity (four times), Graeme Wood (three) and Tom Moody.

Wood raised the silverware three straight times from 1987 to 1989, and Whiteman said his team should be counted in that same rarefied air.

"No doubt we'll go alongside [Wood's teams].

"I think with the one-day stuff [three consecutive Marsh Cups] as well, we'd have to be up there with the great WA teams.

"Hopefully there's more success down the line."

Unlike last summer, when WA dominated virtually from the opening round, this season they had to scrap their way to the title, only sealing their place in the decider on the last day of the round-robin stage after two late wins.
