A sin-binning for Man of Steel Sam Tomkins rattled head coach Shaun Wane despite Wigan Warriors comfortably seeing off struggling London Broncos.
Josh Charnley and Iain Thornley touched down twice each, adding to four-pointers from Michael McIlorum, Sean O’Loughlin and Blake Green – Pat Richards added to his own score by kicking 12 points.
Tomkins went over for the fourth time this season but after seeing yellow 16 minutes in fort dissent, his coach admitted his frustrations.
“That was the wrong call from the in touch judge, but that is no excuse and it won’t happen again,” Wane told the BBC.
“The referees make mistakes just like players. They are incidents for me to sort out in the week and not for Sam to do it on the field.
“He is a competitor, I understand he wants to win but he just cannot do that.
“I don’t know what he said to the referee but it must have been severe for him to sin-bin him.”
Wigan now sit three points behind early Super League leaders Huddersfield Giants – the only side to have maintained their 100% record this season.
The Broncos twice took the lead through first half tries from Liam Colbon, Kieran Dixon and Chad Randall – Wigan conceding 12 points in Tomkins’ absence.
But despite the early problems caused by London, Wane was satisfied with his side’s response after the break.
“We fixed it at half time and to nil them in the second half and win by 30 points is a good effort,” he added.
“They are a tough group and they were harsh on themselves. I started the ball rolling at half time and then all the players spoke up, they’re an honest group.
“We scored some great tries and to come away with the win we did, with such a young team was pleasing.”
