Eight days after the remarkable 10-1 win over Stoke City, Travis Binnion's side raced into a comfortable 5-0 lead on Wearside, with Omari Forson's 47th-minute strike adding to Joe Hugill and Shola Shoretire's first-half braces.
Reds captain Hugill set the ball rolling with a rapid opener inside the first minute, firing low past former United goalkeeper Nathan Bishop. Shoretire doubled our lead in the 15th minute with a confident finish, after the hosts conceded possession just outside the box.
Hugill, a boyhood Sunderland fan, grabbed his second of the first half when a defensive header fell short of Bishop, before Shoretire rounded the keeper to make it 4-0 in injury time.
