Leeds dominated a first half which ended goalless but made the breakthrough in the 67th minute through Joel Piroe. Fine play from Georginio Rutter released Dan James down the right flank and James then delivered a perfect cross to the far post where Piroe arrived to convert from close range.
The Whites threatened to double their advantage two minutes later as Crysencio Summerville charged into the box after brilliant skill by Rutter but Summerville's cut back was cleared. Yet a Whites second quickly arrived in the 70th minute through Sam Byram who powered home a brilliant header from a James corner for his first Leeds goal since December 2015.
Brilliant skill by substitute Jaidon Anthony then created the winger a chance with four minutes left only for his shot to be saved but Anthony got himself on the scoresheet two minutes later with a home debut goal after brilliant work by the extremely impressive Rutter.
The record signing turned in midfield before sending a perfect through ball for Anthony who raced in on goal before slotting past Hornets keeper Daniel Bachmann.

11. Georginio Rutter
9 - An outrageous display of skill. A joy to watch. Yes, he should have scored in the first half, but he put on a show for the remainder with the ball at his feet. Photo: Bruce Rollinson

8 - Made a big impact, admittedly against a beaten side. Should have scored his first chance but took the second very well. Photo: Bruce Rollinson
