Wrexham 0-0 Dover Athletic
Promotion rivals Wrexham and Dover each climbed a place in the National League as they battled to a draw at the Racecourse.
While it was goalless in north Wales, Sutton United's 3-1 home defeat by Tranmere Rovers allowed the Dragons and the Whites to profit.
Dean Keates' hosts went up to second, two points behind leaders Macclesfield.
Dover, guided by Chris Kinnear, are a point behind Wrexham at the halfway stage.
Wrexham boss Dean Keates told BBC Radio Wales: "I think we were the more capable team and if anybody was going to win the game, it was going to be us.
"I thought we were outstanding, to be honest. They're difficult to play against - a lot of long balls coming into your box - they put you under a lot of pressure.
"First 20 minutes they pinned us in but we defended well, bodies on the lines. You have to do the basics and we did that very well."
