Dynamo took the lead in the twenty-sixth minute, Kris Nurse converting a left wing centre at the near post, this proving to be the only goal of a disappointing first half.
Things warmed up within two minutes of the restart. Mark Danks floated a free kick into the Dynamo area which eluded everybody, including goalkeeper Jack Harvey, for the home side's equaliser.
Danks gave Sutton Coldfield the lead in the sixtieth minute when Harvey dropped a long ball, pouncing to drive the loose ball home.
Dynamo came straight back and were level within two minutes. A move involving Martin Bowles and Lee Morris set up Nurse to equalise.
Things were to go even better for Dynamo, with two outstanding goals. A clearance out of defence was picked up just inside the Sutton Coldfield half by Luke Smithson, who set off on a solo run and slotted home in the sixty-sixth minute.
Seven minutes later another long ball out of defence from Dynamo was collected by Nathan Kelly, who held off a challenge from Joel Kettle to lob the ball home with style.
Sutton Coldfield pushed to get back into the match, but Dynamo's defence held firm and give the away side a deserved win.
