An unbeaten half-century by Ben Duckett after Mitchell Santner's three-wicket haul guided Trent Rockets to a nine-wicket triumph at Cardiff. It never looked enough to trouble Rockets and Duckett put on 75 for the first wicket with Finn Allen, who was pinned in front lbw by Rachin Ravindra. In the other game, the capital city derby went the way of London Spirit, who beat MI London by seven wickets at the Oval. Jamie Overton took 3-30 as MI London, led by Will Jacks' 65, reached 5-164. Spirit reached the target with 11 balls to spare, South African opener Lhuan-dre Pretorius smacking 64, including seven sixes, from 28 balls.
