Victorian youngster Will Pucovski scored 64 off 160 balls before Richardson had him caught behind down the leg side.

The 21-year-old had combined with Matt Short (55) for a 114-run partnership.

Victoria will be left to rue none of their batsmen going on with promising starts.

Marcus Harris had earlier looked to be on track for his second ton in as many games when he brought up his 50 with a sweetly struck cut shot.

But the left-hander had a lapse on 69, trapped lbw while ambitiously attempting to play across the line of a Matt Kelly delivery.

His was one of three dismissals for Victoria in quick succession after lunch.

Ashton Agar's first ball snared skipper Peter Handscomb (12), clean bowled while trying to drive the left-arm spinner down the ground.

Glenn Maxwell was trapped lbw by a searching Richardson inswinger, before Pucovski and Short steadied the visitors.

Victoria had reached 1-79 at lunch after Handscomb won the toss and elected to bat, with Nic Maddinson (37) the first to fall.

Aaron Finch was a notable omission for Victoria, being rested after suffering a back spasm during the match against SA.

Richardson (3-45) bowled superbly for WA, striking immediately with the new ball when he coaxed an edge to second slip from Short.
