Lancaster still improving - Radford
Hull head coach Lee Radford hailed winger Callum Lancaster as a star in the making after he bagged two tries in the 50-12 romp over London.
Lancaster, 17, struck in either half in just his second senior start as part of a nine-try Hull blitz, ending a four-game losing streak for the Black and Whites.
"I'm really pleased for Callum," Radford said. "He is still really raw, but physically he is in great shape and can get better.
"He has pace to burn and the more we can get him in space the better for us.
"Everything today was really based around getting the win.
"It was ugly at times, but when we got in the groove we looked good."
After James Greenwood opened the scoring for the hosts, Hull hauled themselves level when Gareth Ellis powered over from close range.
And, having picked up the pace as the half wore on, the visitors added three further scores before the interval through Lancaster, Joe Westerman and Jamie Shaul.
Things got even worse for the Londoners minutes before the break when hooker Scott Moore was red-carded for a challenge on Lancaster.
The game followed a similar pattern in the second half, London emerging the stronger and striking first through Mason Caton-Brown.
But once again Hull flexed their muscles, and one-man advantage, as the minutes ticked by, with Danny Houghton, Westerman and Lancaster crossing to put the game to bed.
There was still time for the visitors to rack up the half-century, with Jordan Rankin and Fetuli Talanoa touching down in the final four minutes.
London coach Joe Grima, who saw his side lose their 15th straight Super League contest, admitted it had been a tough day at the office for his side.
He said: "Scott is an aggressive player, but not a malicious one, so I shall have to look at the red card again.
"We were hit by injuries during the game and the truth is we just did not have the troops.
"We ran out of interchanges and it was just a case of filling places.
"Attitude is not losing us games - it is the inexperience.
"But if we continue to run hard and tackle hard, our luck will change."
