Adrian Segecic’s double mistake gifted Hull a narrow victory at Fratton Park.
The away-day specialists had been restricted to just one shot until the 73rd minute, such was the dominance of John Mousinho’s men.
Then Segecic was caught in possession to allow John Lundstram into the box and, when he made amends, produced a short backpass to put Nicolas Schmid in all sorts of trouble.
When Oli McBurnie slid in to challenge the keeper, the ball fell to Matt Crooks to finish into the empty net and secure a 1-0 victory.
Like Sheffield United, it was more agony for the Blues, who had plenty of the ball, a large number of corners and vastly more shots than the visitors.
