Hull City 5 Southampton 0
The home side took the lead on seven minutes as Marney, from just outside his own box, played an inch-perfect through ball over the top to Campbell, who raced on to it and placed the ball past the stranded Michael Poke with ease to make in 1-0 to Hull.
Hull went 2-0 up on 55 minutes as the Southampton defence failed to clear a Sam Ricketts throw-in, allowing the ball to fall to the feet of Pedersen who smashed the ball into the back of the net from six yards.
A minute later the home side were further in front as Turner registered his second goal in a week as Marney delivered a superb cross from the right straight onto the head of the centre-back, who powered in a header from six yards to make it 3-0 to the Tigers.
Brown's men then went 4-0 in up on 68 minutes as Marney ran on to a lay-off from Campbell and hit a 25-yard piledriver which saw the ball fly into the bottom corner of the net to cap off a great performance from the Hull midfielder.
Substitute Michael Bridges nearly grabbed a goal towards the end of the game, but couldn't reach it as Marney's clever chip over Poke came back off the post.
Hull made it 5-0 in injury time as substitute Hughes finished off a neat move with a curling right-footed effort from ten yards.
