Goals from Marshall Willock and Luke Rawson either side of the interval saw Chesterfield’s youth team beat their Port Vale counterparts 2-1 to secure a place in the third round of the FA Youth Cup.
Early on, Alex Render and Aaron Sennett-Neilson combined to set up Robbie Foster who shot wide under pressure from a defender.
Vale skipper James Steele tried a shot from around 20 yards out which was saved by Brad Jones.
Ify Ofoegbu, on the right-hand side of the area, then shot wide.
Charlie Wakefield looked to pick out Luke Rawson’s run into the area, but his through-ball was just out of the striker’s reach.
Vale’s Harry Benns produced a good run down the right-hand side before firing in a shot which was saved by Jones at his near post.
Foster went close with a curling effort which was touched wide by keeper Dequan Crockwell.
Willock gave the Spireites a 32nd minute lead when he powered a header into the net after meeting Wakefield’s corner.
Steele headed wide early in the second half and Lucas Green-Birch put an effort over.
Sennett-Neilson tried an effort from distance which went well wide.
Ofoegbu cut in from the left and fired in a shot which was deflected wide.
The visitors had a good chance when Zak Hill, who was unmarked, headed wide.
Rawson (72) put the Spireites further ahead after receiving the ball from Ofoegbu inside the area and beating Crockwell with a low finish.
As Vale looked to produce an immediate response, Green-Birch fired in a long-range effort which forced a good save from Jones.
Joshua Ryder (79) pulled a goal back for the visitors, stabbing in at the far post after a low shot was deflected into his path.
Vale never seriously threatened to force an equaliser, however, with Chesterfield booking a trip to Swansea City in the third round of the competition.
