Chasing a target of 171, the Capitals reached 172-3 in just 18.3 overs, with nine balls to spare, powered by a scintillating 91-run partnership between Brevis and Parsons for the third wicket. Brevis, finally delivering on his burgeoning potential, blazed his way to an unbeaten 75 off 38 balls, striking four boundaries and seven sixes.
Parsons, after a fine contribution with the ball, anchored the innings with a composed 60 from 44 deliveries, combining patience with timely aggression. Support from Connor Esterhuizen (22 off 19) and Shai Hope (11 off 9) helped maintain momentum as the Capitals chased down the target with apparent ease.
Earlier, the Sunrisers looked set for a strong total after Jonny Bairstow compiled a rapid 50 from 36 balls and Jordan Hermann added 41 from 30 deliveries. However, key dismissals late in the innings saw their hopes unravel.
Quinton de Kock fell for 19 to Roston Chase, while Hermann was trapped lbw by Parsons, and Bairstow fell to Keshav Maharaj (2/24). Parsons and Maharaj then ripped through the middle and lower order, with Parsons finishing with figures of 3-10. Only a late cameo from James Coles (17 off 4) added late runs, lifting the Sunrisers to 170-7.
