Boro fell a goal behind when Hull’s Allahyar Sayyadmanesh headed The Tigers ahead from a corner five minutes before half-time.
The hosts reacted well, though, scoring three times in a six-minute spell after goals from Hayden Hackney, Cameron Archer and Chuba Akpom.
Here’s how each Boro player fared at the Riverside:
9. Marcus Forss - 5
Saw an early effort saved by Hull goalkeeper Karl Darlow but struggled to get into the game after that. Was subbed at half-time. 5 Photo: Michael Regan
10. Chuba Akpom - 8
Struggled to get into the game in the first half but got on the scoresheet again with a quick turn and finish to score Boro’s third. Picked up pockets of space and had more of an influence after the break. 8 Photo: Stu Forster
11. Cameron Archer - 7
Was also on the fringes in the opening 45 minutes but took his goal well to put Boro ahead after charging past Hull defender Sean McLoughlin. 7 Photo: Getty Images
12. Isaiah Jones - 9
(for Forss, 45) Made an immediate impact on the right after coming on at half-time, registering two assists for Boro’s first and third goal. Could have had another one too during a superb 45 minutes. 9 Photo: Alex Burstow
