Western Australia 9 for 519 dec (Marsh 214, Philippe 65, Inglis 58, Stoinis 56, Pattinson 4-117 and 0 for 9 beat Victoria 341 (Harper 72, Harris 69, Pucovski 64, Short 55) and 186 (Maxwell 57) by nine wickets
Jhye Richardson, Marcus Stoinis and David Moody combined to dismantle Victoria's second innings at the WACA and set up a clinical 10-wicket victory for Western Australia.
Only Glenn Maxwell passed fifty and when he became Stoinis' third wicket it virtually ended Victoria's hopes of departing the west with a draw. Their last five wickets fell for 38 to leave a target of just nine shortly after tea which Western Australia achieved for the loss of Sam Whiteman.
Victoria had resumed on 1 for 17 - 161 behind - following the loss of Marcus Harris the previous evening and suffered an early blow when Will Pucovski, who is expected to push hard for a Test call-up, edged behind off Moody.
Stoinis claimed his first of the innings when he had Peter Handscomb lbw although the Victoria captain looked far from impressed with the decision and Matthew Short also gave the impression of being hard done by when he was later pinned for a duck.
Between the two lbws for Stoinis, Richardson produced a good delivery to take the edge of Nic Maddinson and Victoria were five down before lunch.
Maxwell and Sam Harper offered some hope in a stand 70. The partnership included another tasty contest between Maxwell and Richardson which stems back to the Marsh Cup encounter on this ground last month.
In the first innings Richardson won the battle when he had Maxwell lbw for 1 but this time the duel went on longer with Maxwell sending a six over third man. He didn't fall to Richardson on this occasion although the quick still had a hand in Maxwell's dismissal when he settled under a swirling top-edged pull at long leg.
The lower order managed to extend the innings beyond tea but not by much. James Pattinson was given out caught down the leg side - another who looked disgruntled by the verdict - and Moody bagged his third when Harper was well caught at second slip by Shaun Marsh.
Marsh, whose career-best 214 helped build the matchwinning lead, then outdid himself with a very sharp take at slip when Peter Siddle edged Ashton Agar.
