Somerset 158 for 1 (Banton 79, Kohler-Cadmore 43) defeated Hampshire 157 for 7 (Prest 51) by nine wickets.
Tom Banton's commanding performance led Somerset to a comfortable nine-wicket victory over Hampshire, bringing the defending champions within a point of securing a spot in the Vitality Blast quarter-finals.
Banton, opening the innings, smashed an unbeaten 79 off 52 balls, sharing partnerships of 81 with George Thomas and 77 with Tom Kohler-Cadmore to easily chase down 158 at the Utilita Bowl.
Jack Leach, putting aside his England Test omission, bowled economically with figures of 2 for 23, while South African fast bowler Migael Pretorius impressed on his Somerset T20 debut, also taking two wickets. Only Tom Prest's 51 provided resistance against Somerset's dominance.
With this win, Somerset moved to 15 points, and only Gloucestershire, two points behind with one game left, can potentially stop them from advancing. Hampshire's three-year streak of reaching the knockout stages has ended.
James Vince opted to bat first, and he, along with Ben McDermott, started strong, scoring 45 in the first five overs. However, Somerset seised control with the introductions of Pretorius and Leach. Pretorius, in his debut T20 over for Somerset, bowled Vince with a stunning delivery that clipped the top of off stump.
McDermott, who had hit a few boundaries, was dismissed by Leach with a dart, marking the first time the spinner took a T20 wicket that wasn't caught. From 78 for 2 at the halfway mark, Hampshire struggled to gain momentum as Joe Weatherley and Benny Howell quickly fell.
Tom Prest attempted to revive the innings, emulating Vince's elegant offside play, and added 32 runs with James Fuller. Prest, returning from a shoulder injury, scored his fifth Blast half-century in 31 balls but was dismissed the next delivery, followed by Fuller and Toby Albert's quick exits. Liam Dawson's late 15 off nine balls pushed the score to 157, which seemed insufficient.
Banton and Thomas began aggressively, with Banton setting the tone by clipping the first delivery for four. Howell managed to edge out Thomas for a run-a-ball 29, bringing Kohler-Cadmore to the crease. Kohler-Cadmore rapidly added 43 not out, including two fours and three sixes, sealing the victory.
Banton, the standout player in the 2024 Blast, reached his third fifty of the campaign in 34 balls and surpassed 400 runs for the season. Somerset secured the win with 12 balls to spare.
