Despite their player disadvantage after Byrne’s yellow card in the opening stages of the game, it was Wigan who raced ahead courtesy of a lung-busting run from Marshall.
The Wigan winger intercepted a pass virtually on his own try-line and showed incredible pace despite the early summer warmth at the John Smith’s Stadium.
Harry Smith’s boot put the visitors 8-0 up and Huddersfield finally got on the scoresheet after Byrne’s return to the field.
Wallis ran in from deep in his own half in similar fashion to Wigan’s score, and rounded Marshall before touching down to claw down the gap to two points.
French easily ran in with 20 minutes on the clock to give the Warriors a six-point advantage before Wigan took control in the second half.
Marshall’s second try came as he worked onto Jai Field’s pass to work his way over following a repeat set and before long he had his third.
A flowing set of passes out to Marshall on the wing saw him weave his way into space to touch down and put the visitors out of sight.
The pick of Wigan’s tries will arguably be Leeming’s score as the game ticked down as he worked onto a sensational late offload from French to race in.
Huddersfield finished the match with 12 players as Esan Marsters stuck a leg out to bring down French in the midst of another Wigan attack.
Wigan took no time at all to make their advantage count, though, with French once again in the thick of the action as he sent through Miski to break the 40-point mark.
Miski doubled his tally with two minutes remaining having run through with ease, with his score ensuring the Cherry and Whites would move to the Super League summit on points difference – and with a game in hand.
