England all-rounder Nat Sciver-Brunt timed her introduction to perfection as 32 off 19 balls batting down the order secured Trent Rockets' progress to the final of The Hundred with a seventh successive victory.
Chasing 118 to win, the league leaders slipped to 10-3 against Southern Brave, the lowest powerplay score in the history of the competition, and even though passing 27 guaranteed their place in the final, the result remained in doubt.
Sciver-Brunt came in at number seven with the score on 66-5 and with 31 deliveries remaining - Ash Gardner having top-scored with 37 - and her experience avoided further drama.
She was run out going for a second which would have clinched victory, but Rockets still won with two balls to spare.
Southern Brave's 117-5 was built around their top order with Maia Bouchier scoring 38, Lizelle Lee 31 and Laura Woolvaardt adding 24.
They will get a second chance as they had already secured a place in the eliminator on Friday at The Kia Oval. Brave will discover their opponents on Tuesday, who will either be third-placed SunRisers Leeds or fourth-placed Manchester Super Giants who play each other at Emirates Old Trafford in their final group match.
Sciver-Brunt said: "I'm happy to be on the winning side. The wicket was a bit slow, and they bowled pretty well in the first half."
On batting down the order, she said: "It was a bit tactical and a bit injury management. We have got a lot of people in form and high on confidence.
"We have balanced our side nicely and building up to Sunday we sort of know what we need to do."
