Jordan Rhodes struck twice as the reserves maintained a 100 per cent record in the league this season.

On a muddy pitch, Town took a first-half lead through the striker before Grays equalised after Michael Synnott was harshly judged to have brought down a home player in the penalty area.

Liam Trotter put Blues back in front after the break with Danny Haynes adding a third. Rhodes grabbed a second and Town's fourth after Grays had reduced the arrears.
