Wigan acquired his services from Rotherham United in June 2005. Prior to Rotherham, Pollitt had also played for Oldham Athletic and Sunderland but his move to Wigan (initially as cover for existing goalkeeper John Filan) following advice from Paul Barlow, gave him the chance to play Premier League football. His outstanding performances earned him a regular first team place, and in February 2006 he helped Wigan to a place in the 2006 League Cup Final. In the semi final he saved a penalty from Arsenal's Jose Antonio Reyes to help Wigan triumph. In the final itself a hamstring injury in the opening minutes meant that he had to be substituted in the 15th minute, and was replaced by Filan.
