Wigan were firmly in control with tries from Frano Botica, Denis Betts and Sam Panapa, all improved by Botica, in the first 25 minutes. But Town hit back bravely with tries by Mark Mulligan, and Paul Penrice.
Dean Marwood, the League's leading goal-scorer, added both goals and Wigan were grateful for Phil Clarke's try to ease them to a 24-12 victory .

With the three other Second Division matches frozen off, Featherstone Rovers moved further ahead at the top by winning 30-8 at London Crusaders.
Hunslet face a fine after refusing to play at Batley, even though the pitch was passed fit by the referee. Ryedale-York's home game against Barrow was called off during the second half with Ryedale leading 60-0.
