The 20 year-old became just the second Victorian after Dean Jones to crack 200 at the WACA Ground, compiling a brilliant 243.

It was part of the visitors' first innings total of 504, securing them a 296-run first innings lead.

On Wednesday he got especially good support from Matt Short (80) while Cameron White chimed in with 39.

Marcus Stoinis took 4-73 for the Warriors and while Simon Mackin took three wickets, he went for 138 in 22 overs. Debutant leg spinner Usman Qadir picked up two scalps.

Victoria dominated again with ball in hand, Chris Tremain (2-24) Andrew Fekete (1-7) and Scott Boland (1-9) ripping open the WA top order in the final session, with the home side still trailing the tourists by 251.

The not out WA batsmen overnight are Stoinis (3) and Josh Philippe (9) with WA 4-45.
