Victoria 6 for 282 (Harris 100, Chandrasinghe 67, Steketee 2-55, Kuhnemann 2-55) vs Queensland
Harris, who has played 14 Tests, starred after Victoria were sent in at the MCG with a fluent 148-ball knock to defy a strong Queensland attack.
Harris was in an aggressive mood, particularly against left-arm spinner Matthew Kuhnemann who he hit for six over deep midwicket after lunch. He also unleashed reverse sweeps before hitting his ton conventionally with a beautiful straight drive off seamer Xavier Bartlett.
But Harris didn't add to his score and holed out off a long hop from Kuhnemann to trudge off disappointed at throwing his wicket away.
A watchful Chandrasinghe played a support role to Harris and endured sharp bowling from quicks Mark Steketee and Michael Neser before tea.
He reached his half-century in style with a boundary before falling to Kuhnemann lbw. It triggered a late collapse for Victoria, who lost four wickets in the final session after threatening to take control.
Their hopes of a formidable first innings total rests on stand-in captain Will Sutherland, who played aggressively before the close, and wicketkeeper-batter Sam Harper.
Queensland showed signs of weariness just five days after Brisbane Heat's barnstorming run to the BBL final ended in heartbreak against Perth Scorchers.
Five players backed up from that Optus Stadium epic, including Kuhnemann who conjured bounce and spin as the day wore on to finish with 2 for 55 from 21 overs.
Queensland had for long stretches been left frustrated with several edges falling short of slips, but their toil was rewarded in the final session with hardworking Steketee claiming the wickets of Matt Short, the BBL player of the season, and Mitchell Perry.
Former Western Australia quick Liam Guthrie struck early in his Bulls debut when he dismissed opener Travis Dean for six in the only wicket of the first session.
The match heralds the return of the Shield after a lengthy break due to the BBL season.
Defending champions Western Australia are the runaway leaders with 32 points and restart their season on Friday against South Australia at Adelaide Oval.
