Troubled Reading gained some respite, thrashing Arsenal Under-21s 5-2 to maintain their 100 per cent record in the competition.
Kelvin Ehibhatiomhan scored twice for the Royals, who are bottom of League One, but missed out on a hat-trick when Ovie Ejeheri saved his penalty kick.
Arsenal's Fabio Vieira converted a spot-kick and had another saved, while Khayon Edwards hit his side's second.
Caylan Vickers, Harvey Knibbs and Sam Smith were also on target for Reading.
Aaron Pressley's double helped Stevenage - who were already unable to qualify - to finish their campaign in style, triumphing 5-2 against Crystal Palace Under-21.
