A doughty century from Sam Whiteman has moved Western Australia a step closer to breaking their Sheffield Shield title drought as Victoria's bowlers struggled for impact on the benign WACA pitch.
Needing just a draw to claim the title, WA reached 5-217 at tea on day four of the five-day contest.
The home side, who have not won the Shield since 1999, are now 297 runs clear of the visitors.
Whiteman was the backbone of the innings with his unbeaten 104 stretched over three sessions and 276 balls.
Allrounder Aaron Hardie provided invaluable support with 55 not out, with the pair's 107-run sixth wicket partnership consuming 40.1 overs.
With time starting to run out, Victoria failed to make a much-needed breakthrough with the new ball taken after lunch.
Test paceman Scott Boland was at his frugal best, returning figures of 2-29 from 21 overs, but without a wicket on day four.
Victoria knocked over allrounder Teague Wyllie (23) and the hard-hitting Josh Philippe (1) in quick succession before lunch, but wicket-taking opportunities were at a premium .
