Victorian paceman Will Sheridan engineered a stunning 212-run victory over Western Australia to ensure the Bushrangers remain in the hunt for the Sheffield Shield final.

Sheridan finished with 5-15 as the Warriors surrendered any chance of chasing down the target of 367 at the WACA Ground.

In just 30 minutes, WA went from 0-63 to 6-82 and their innings was wrapped up for 154 just before tea on Sunday.

Nathan Coulter-Nile collected four sixes as he slugged an unbeaten 44 while Victorian seamer Jayde Herrick cleaned up the tail for a deserved 3-66.

Sheridan revealed he had been given a spray from coach Greg Shipperd for overpitching the ball in the first innings, where he picked up 2-73.

“On this wicket, even though there is bounce, you really have to hit the wicket hard and (Peter Siddle) was a prime example of that in the first innings,” he said.

“A bit of a kick in the bum seems to have worked for myself and Jayde Herrick.”

Victoria declared at 8-390 after adding 29 more runs to their overnight score but Western Australia started the run-chase brightly, with Liam Davis and Wes Robinson adding 63 for the first wicket.

But the introduction of Sheridan changed the game.

After an opening full-toss that was smacked for four, Sheridan removed Davis for 38 and the next ball trapped Shaun Marsh lbw for a duck.

Adam Voges, facing a king pair, watched the hat-trick ball pass but he lasted just one more ball when he edged Sheridan to wicketkeeper Ryan Carters.

With the wickets of Travis Birt and Craig Simmons, the 24-year-old left-arm paceman, playing his seventh first-class match, now had five wickets in 20 balls.

At the other end, Robinson could only watch as his team-mates crumbled but he was eventually out for 41 after mistiming a pull shot.

Victoria will play NSW in the final round of fixtures and again need an outright victory to have a chance of sneaking into the final.

A WA win over Tasmania will ensure that the Warriors host the final and skipper Voges said that match was now where the Warriors’ focus lay.

“We’ve two poor days out of our last four games,” he said.

“While it’s disappointing in the last two days that we haven’t executed nearly as well as we should have, at the end of the day we’re still four points clear at the top of the ladder from what we’ve done during the year.”
