Victoria captain Cameron White ensured his side claimed first-day honours with an unbeaten 88 in a total of 6-259 on Friday in their Sheffield Shield clash with South Australia.
White's display of determination on a difficult batting wicket at the MCG follows his 72 against NSW in the previous round, also at No.7 after being shifted down the order from No.3.
No.6 Peter Handscomb (69) and White shared a sixth-wicket partnership of 131 after Victoria had been struggling at 5-83 after losing the toss.
The home side had recovered from 2-14 to reach 2-82 before left-armer Gary Putland triggered a dramatic middle-order collapse of 3-1 in the sixth over after lunch.
Putland was threatening all day for the last-placed Redbacks and finished with 4-48 off 26 overs.
Chadd Sayers (2-61) struck in the second over to remove Ryan Carters caught behind for a duck.
Aaron Finch followed for nine at 2-18, caught at first slip by Michael Klinger off Sayers' bowling.
Putland ended the 64-run partnership between David Hussey (29) and Chris Rogers (39) as Rogers edged a ball onto his stumps.
Glenn Maxwell was lbw to an inswinger for a third-ball duck and Hussey was Putland's third victim, caught at second slip by Phil Hughes two deliveries later.
Handscomb hit eight fours in his three-hour knock before falling to Putland in the third over with the second new ball at 6-214.
John Hastings is unbeaten on 14.
White, who hit seven fours and two sixes from 179 deliveries, admits he'd prefer to be batting at No.5.
"It's been quite hard work on the wickets this year so I've made the move to go back down," said White, who has lifted his season's tally to 208 at 41.60 following his two successive half-centuries.
White said the move to No.7 came after the national selection panel discussed giving Maxwell more opportunities up the order at state level.
"As soon as I went back there I said to (Victoria coach Greg Shipperd) 'I don't want to stay there, I want to go back up'," White said.
"He said I'd have to make some runs.
"Number five is the position I've played for a long time and I feel as though that's where I'm suited to."
White said he would have had no hesitation in sending the Redbacks in if he'd won the toss.
"It was quite overcast for the first hour or so, so I'm pretty comfortable with the position we're in," White said.
Putland's three-wicket over after lunch put the Redbacks back in the game, although their advantage faded late in the day.
"It was a good feeling," Putland said of his triple-breakthrough.
"It was coming out well all day and I felt pretty confident."
