The Renegades captain hit 64 runs from 29 balls (six 4s, four 6s) as his side chased down the 137 runs required for victory in 13 overs.
“Just to put the finishing touches on our squad’s preparation for the first game has been really nice," Finch said.
“I feel good with my game at the moment as do a lot of the players.
“It was nice to win both games and play really good cricket.
“Sometimes your standards can slip slightly, but we’re really happy with how everyone went over the last couple of days.”
When Finch was dismissed the score was 1-74 from six overs.
His opening partner Marcus Harris (47 not out off 30 balls) then took over and together with Cameron White (20 off 20 balls) guided the side to a nine-wicket win.
Earlier Kane Richardson led the way with the ball picking up 2-27 from his four overs.
Finch and Tom Cooper showed they’ll be handy options with the ball this season combining for 2-8 off three overs.
The Renegades will now head back to Melbourne to fine-tune before travelling to Hobart to take on the Hurricanes in their opening match of the BBL on Thursday.
“One really positive thing that we’ve got going into the first game is we’ve got 14 or 15 guys who are a realistic chance of playing in that first game," Finch said.
“It’s great to have options with how you structure up your team.
“When you’re trying to find guys to fill spots that can be a dangerous place to be but when you’ve got three or four guys fighting it out for a couple of spots that’s a great position to be in as a squad.”
