At the half-hour mark, Abel Hernandez opened the scoring for Hull City after finding Jake Livermore’s pass, to fire a left-footed low shot from outside the penalty box into the bottom right corner of the net.
Five minutes to the break, the guests went 2-0 up, following an own goal by Derby County as Moses Odubajo’s shot was deflected by Jason Shackell into the net.
The Tigers headed down the tunnel with a 2-0 lead at the interval, a very comfortable results for Steve Bruce’s side.
Derby struggled throughout the second half; their attempts to reduce the deficit failed, as Hull City defenders were alert to clear any danger.
Two minutes to full time, Elmohamady missed a chance to score a third for his side, as he broke into the box, but his shot went wide.
In the eighth minute of added time, Hull made it 3-0. Following a poorly executed corner for Derby, the guests launched a counter attack and Andrew Robertson sent the ball into the far corner of the net.
