Victoria's impressive fast bowling stocks were again on display as the Sheffield Shield finalists comfortably bowled out South Australia on day one of their match in Adelaide.
SA were dismissed for just 260 under sunny skies at Karen Rolton Oval as the Vics engaged in something of a bowl-off, as they seek to settle on a preferred XI for next week's final at Junction Oval.
Victoria ended the day at 1-28 against the winless Redbacks in a match that is inconsequential to the final Shield standings.
The Vics, however, suffered a blow with Nic Maddinson in serious danger of missing the final after the in-form batsman suffered a thumb injury attempting to take a catch.
Victoria took the unusual step of lining up with four paceman, plus a spinner in Jon Holland, with Andrew Fekete and the team's leading wicket-taker Scott Boland rotated out of the side.
James Pattinson and Peter Siddle showed all their quality by following up their wicket-taking in last week's crucial win over New South Wales with several top-order scalps.
Pattinson took 3-52, while Siddle returned 2-15 from 11 frugal overs.
Tremain ran through the lower-order to return figures of 3-38.
Redbacks captain Travis Head top-scored with 67, but it took a handy 59 from inexperienced spinner Tom Andrews to help South Australia reach a position of respectability after being 6-140.
The home side ended the day positively by dismissing Test opener Marcus Harris right on stumps for 16, off the bowling of Nick Winter.
