But competition powerhouse Joondalup claimed its second premiership in three seasons, winning by 402 runs on Sunday a disappointing end to a fairytale season for Gosnells.
Man of the Match Josh Inglis set up the win with a powerful double century equalling the highest individual WACA first grade score of 246.
Joondalup added 116 runs in just 12 overs in the morning to finish on an imposing 6-567, the highest team total in 36 years and the third highest team score in WACA first grade history.

READ NOWGosnells club president Ross Leipold said the Hawks toiled hard on a beautiful batting wicket but the combination of the promising young Inglis and a century by Clint Hinchcliffe set a massive and very daunting total for the Gosnells side to chase.
"This was a task that had to be made in 85 overs and proved to be too hard," he said.
"Matt Leipold batted well for the Hawks finishing on 58 not out."
Leipold said it had been a remarkable season for Gosnells and to rise from 14th on the ladder before Christmas to the State's premier cricket competition grand final was a great achievement.
"While the result did not go our way, the first grade side did the Gosnells Cricket Club proud," he said.
