Hull FC have leapfrogged Widnes Vikings in the Super League table after beating the Cheshire outfit 22-8 at the KC Stadium.
The hosts took an early lead when Tom Lineham touched down in the corner following Jamie Shaul's clever turn and pass.
Widnes levelled the scores midway through the first half through captain Kevin Brown, but replays suggest that Patrick Ah Van knocked on in the build-up to the try.
However, Hull restored their advantage with 11 minutes left of the opening period when Lineham sprinted 80 metres to score.
The pacey winger completed his hat-trick within moments of the restart after winning another lengthy foot race to touch down.
Hull wrapped up victory with 13 minutes left after Shaul scored the fourth try of the evening for Lee Radford's men.
Widnes scored a late consolation when Ah Van touched down in the corner, but Hull were able to hold on for a victory that sees them move above Warrington Wolves in the standings.
