Portsmouth came from behind to beat Everton, the runaway leaders of Premier League 2 Division 1, and reach the knockout stages at the Toffees' expense.
Hosts Pompey needed a point to qualify at Havant & Waterlooville's Westleigh Park, but the Toffees, who had to win, went ahead through Bassala Sambou's 29th-minute opener.
Ben Close equalised immediately after half-time and Nicke Kabamba clinched a 2-1 victory in the 77th minute.
Portsmouth finish top of Group D with 11 points, one ahead of fellow qualifiers Norwich City, with Everton and Wolverhampton Wanderers failing to progress.
