South Australia made a roaring start on day one of their Sheffield Shield clash with Victoria with pacemen Joe Mennie and Carl Tietjens dismantling the Bushrangers' top order.
Victoria won the toss and elected to bat first in mainly overcast conditions but they find themselves in a world of trouble at 5-96 at the lunch interval.
Mennie was the chief destroyer for the Redbacks with 3-11 off 8.5 overs while Carl Tietjens (2/25) chimed in with the big scalps of skipper Cameron White (31) and Robert Quiney (45) approaching the lunch break.
Mennie's first wicket came on the third ball of the day, when he forced a tentative Chris Rogers (golden duck) to inside edge a ball that trickled back on to his stumps.
The Redbacks quick had the enviable figures of 2-0, when Aaron Finch was superbly snaffled at third slip by James Smith for a duck as well.
The Bushrangers slumped to 2-5 after the Finch wicket and looked to be in all sorts of strife.
But Quiney and skipper Cameron White dug in for the Bushrangers, leading a mini revival.
Quiney, in particular, was driving the ball beautifully down the ground (six fours), seeming like the only Bushrangers batsman willing or able to dictate terms to the bowlers.
The story could have been a whole lot different, though when White was dropped on five by his counterpart, Michael Klinger at first slip off the bowling of Peter George.
A close call for LBW on 20 off the bowling of Tietjens seemed to invigorate a rather restrained White, who struck some telling boundaries square of the wicket on the off side.
However, just as though he looked as if he might be in for the long haul, the skipper was on his way when he got a slight inside edge on to his pad that ballooned up to short leg.
It became a double blow for Victoria when Tietjens trapped Quiney LBW not long after, and their pain was escalated when youngster Peter Handscomb (six) had his stumps shattered, to be Mennie's third victim in the last over before lunch.
Not-out batsman Andrew McDonald (seven) will need all of his experience to dig Victoria out of a deep hole at lunch on day one.
