The total, however, proved insufficient as Tristan Stubbs smashed an unbeaten 52 off 28 deliveries while Marcus Stoinis struck a 25-ball 46 to help the already eliminated Brave end their campaign on a winning note.
That brought Stubbs and Stoinis together, and the pair quickly shifted the momentum towards Brave.
Stubbs had scored 20 off 10 when Miller was dismissed, but Stoinis soon moved ahead of him with a flurry of boundaries.
Stoinis struck three sixes and four fours before Ben Sanderson ended the 70-run stand, which came off 41 balls, by dismissing the Australian.
Rockets eventually found some momentum through their sixth-wicket stand between Santner and Gregory.
Trent Rockets' hope of finishing top and securing direct qualification for the 2026 Men's Hundred final now depends on the result of the Sunrisers Leeds vs Manchester Super Giants game after the Rockets suffered a six-wicket defeat to Southern Brave at Trent Bridge. Rockets will need Sunrisers to lose to Super Giants, with a win for the Leeds-based side enough to see them leapfrog the Nottingham franchise on net run rate.
Rockets finished on 158 for 5 from their 100 balls, with Mitchell Santner (35* off 23) and Lewis Gregory (28* off 18) adding 66 after they had slipped to 92 for 5. The total, however, proved insufficient as Tristan Stubbs smashed an unbeaten 52 off 28 deliveries while Marcus Stoinis struck a 25-ball 46 to help the already eliminated Brave end their campaign on a winning note.
Jamie Smith and Moeen Ali gave Brave a solid start to the chase with a 42-run opening stand before Rockets hit back with quick wickets, leaving the visitors at 78 for 3 from 52 balls. Craig Overton dismissed Smith, while Calvin Harrison accounted for Moeen and David Miller. That brought Stubbs and Stoinis together, and the pair quickly shifted the momentum towards Brave.
Stubbs had scored 20 off 10 when Miller was dismissed, but Stoinis soon moved ahead of him with a flurry of boundaries. Stoinis struck three sixes and four fours before Ben Sanderson ended the 70-run stand, which came off 41 balls, by dismissing the Australian. Brave needed 11 off seven balls at that stage, which became eight off five and six off four before Stubbs deposited a Gregory delivery over deep backward square leg to bring up his fifty and seal victory with three balls to spare. Stubbs finished with four fours and three sixes.
Earlier, after being asked to bat, Ben Duckett struck four boundaries after facing each of the first 14 deliveries of the innings before Stoinis ended his stay. Finn Allen and Aneurin Donald then batted positively, but Brave kept striking at regular intervals to prevent a substantial partnership from developing. Rockets eventually found some momentum through their sixth-wicket stand between Santner and Gregory. Santner struck three fours and a six, while Gregory hit four fours as the pair added 66 off the final 39 balls to give Rockets a competitive total, though it ultimately fell short.
