England newcomer James Rew guided defending champions Somerset to a seven‑wicket victory over last year’s runners‑up Hampshire in the Vitality Blast opener at Taunton. Somerset posted 158 all out, with Will Smeed’s rapid 59 setting the platform and Rew’s unbeaten 47 sealing the win alongside his brother Thomas. Hampshire’s James Vince contributed 58, but it wasn’t enough.

Surrey smashed 213 at the Kia Oval to beat Lancashire by 59 runs, the highest total of the night. Jason Roy returned with 45, while Tom Curran added 49 off 20 balls before Lancashire collapsed for 154. At Lord’s, Sam Billings blasted 84* from 37 deliveries as Kent posted 208/6, defeating Middlesex, who fell short despite Adam Rossington’s 79 on his comeback.

Durham edged Derbyshire by six runs, chasing 204 with Matthew Montgomery top‑scoring 74 not out but lacking support. Jonny Bairstow powered Yorkshire to a seven‑wicket win over Nottinghamshire at Trent Bridge, smashing 83* with four sixes, while former England all‑rounder Moeen Ali added a wicket on debut. Worcestershire claimed an 18‑run victory over Leicestershire, Isaac Mohammed contributing 42, boosting their early table position.
