The all-rounder’s superbly-judged 169-delivery innings saw the visitors reach their 365 target off the penultimate ball to secure a three-wicket Bob Willis Trophy victory in the North group.

Dawid Malan and Harry Brook helped Yorkshire get off the mark with a six-wicket victory over Durham at Emirates Riverside in the North group.
Requiring 68 on the final day to secure the win, the White Rose were frustrated by rain before debutant Malan finished with 73 and Brook – who finished things off with back-to-back sixes – 66 not out to take them to their 171-run victory target.
Surrey-bound Jamie Overton led the way at Taunton with five for 48 to complete Somerset’s 289-run victory over Glamorgan in the Midlands group.

Leicestershire captain Colin Ackermann led the charge to a seven-wicket victory over Lancashire with just eight balls remaining.
Ackermann finished on 73no off just 41 balls as the Foxes chased down their 150 runs off 17 overs target, hitting 10 fours and a six in an extraordinary display of shot-making on a slow pitch after Lancashire were bowled out for 236 in their second innings.
Middlesex claimed maximum points, and the slight early advantage in the South group, with a 190-run win over Surrey at the Oval.
The hosts, set an unlikely 314 for victory after Middlesex’s declaration on 248 for five after 64 was added to their overnight 184 for three thanks to Nick Gubbins (60) and Martin Andersson (51), were skittled for 123.

Former England captain Sir Alastair Cook (66) and 21-year-old debutant Feroze Khushi (45) had put on 86 for the fifth wicket to tilt the balance towards Essex.
