Northamptonshire must win at Gloucestershire and hope other results go their way after thrashing visitors Somerset by seven wickets to stay in the shake-up. Tom Lammonby had top-scored for Somerset with 40, but Rob Keogh's 4-35 gave Northamptonshire the momentum to win with 120 balls remaining. Eighth-placed Warwickshire are the final team in Group A who can still reach the knockout stages following a two-wicket win with seven balls remaining at home to Lancashire. Gloucestershire remain bottom but secured their second win by four wickets against Nottinghamshire at Cheltenham after chasing down a target of 280. Captain James Bracey hit 103 and shared a second-wicket partnership of 153 with Ollie Price, who finished on 59.
