Chesterfield came from 3-1 down to win 5-3 at Mansfield Town in a derby thriller in the EFL Trophy's Northern Group D on Tuesday night, scoring four times in the last half-hour. Dylan Duffy scored two of the four.

Mansfield were already eliminated and were looking for their first points of the competition. Chesterfield had already qualified, but the win took them above Port Vale to the top of the group and earned them a home tie in the knockout stages.

Neither side treated it as a dead rubber. Nigel Clough was without ten regular first-team players through injury, suspension and international duty, and sent out everyone he had. Chesterfield made ten changes from Saturday's FA Cup win over Yeovil Town, with only goalkeeper Zach Hemming keeping his place, and took a packed away end with them.

For an hour Mansfield looked like getting their win. They were ahead inside 13 minutes: Hemming brought down George Maris in the box, and Jon Russell sent him the wrong way from the penalty spot, Chesterfield's tenth game in a row without a clean sheet. Seven minutes later Russell slid in at the far post to turn in Luke Bolton's low cross and make it 2-0.

Chesterfield had chances of their own. Harry Lewis saved from Duffy in the Mansfield goal and Dilan Markanday had two shots blocked. They pulled one back on 45 minutes, when Elliott Hewitt slipped and Joel Randall ran on to Rafiq Lamptey's pass to chip Lewis from outside the box. It was the Bolton Wanderers loanee's second goal in two games.

Mansfield started the second half on top. Hemming made a double save from Bolton and kept out a Regan Hendry shot from more than 40 yards. Russell, chasing a hat-trick, shot high and wide from close range, and Michael Smith headed over and then had a header saved.

On 61 minutes Smith hit the left post and Hendry tucked in the rebound from the left side of the six-yard box to make it 3-1. The lead lasted a minute. Duffy, set up by Fraser Bryden, curled in from the left side of the box on 62 minutes.

On 67 minutes the Mansfield-born captain Tom Naylor headed in Tom Pearce's cross from a corner to make it 3-3, and three minutes later Duffy struck again from the right side of the box, from Markanday's pass, to put Chesterfield in front for the first time.

Mansfield's problems grew. Frazer Blake-Tracy went off after feeling his hamstring, and Clough said afterwards that Rhys Oates, who replaced Bolton, was ill and should not really have played. They still pushed for an equaliser. Hemming saved from the substitute Tyler Roberts, three Mansfield efforts were blocked in the 84th minute and Hemming denied Smith again a minute later.

Instead, two minutes from time, Kyle Knoyle fouled Louie Marsh in the box and Liam Mandeville, on as a substitute, scored the penalty to make it 5-3. Lewis saved twice more from Marsh in stoppage time.

Chesterfield had 56 per cent of the ball. The referee was Sam Mulhall and the crowd at the One Call Stadium was 5,233. The Derbyshire Times reported that it was the first time Chesterfield had scored five at Field Mill since the early 1970s.

Chesterfield return to League Two at Bristol Rovers on Saturday. Mansfield's next game is against MK Dons in League One on 21 November, and Clough is waiting to learn how serious Blake-Tracy's injury is.

“It was a mad eight minutes, it could have been anything in the end with the chances at both ends. We’re disappointed to lose the lead in the manner we did.” — Nigel Clough, Mansfield Town manager, to the Mansfield Chad

“The lads don’t stop. They were 3-3 against Yeovil in the FA Cup on Saturday and they didn’t bottle it. Same tonight.” — Danny Webb, Chesterfield assistant manager, to the Derbyshire Times

Seb Campbell, a 17-year-old midfielder, scored in the ninth minute of added time as Plymouth Argyle beat Swindon Town 2-1 at Home Park to finish top of Southern Group E, ahead of Crystal Palace U21, and earn a home tie in the round of 32.

Argyle, already through, needed only a draw to top the group. Tom Cleverley made nine changes from Saturday's FA Cup win over Alvechurch and started four under-18s, among them the striker Frankie Maund on his first-team debut.

Ronan Curtis, captain for the night, put Argyle ahead from the penalty spot on 27 minutes after Owen Oseni was brought down by Kaelan Majekodunmi. Antwoine Hackford equalised eight minutes later, his shot spinning in off goalkeeper James Storer.

Oseni headed against a post before half-time and Storer turned away a Jaylan Pearman free-kick on 63 minutes. Deep into 10 minutes of added time, with the game seemingly bound for penalties, Campbell headed wide from Xavier Amaechi's cross, then turned in Amaechi's next ball from the right into an empty net. The crowd was 2,508.

“I asked the players pre-match to be hard-working and entertaining and I thought they ticked both boxes.” — Tom Cleverley, Plymouth Argyle head coach, to the Plymouth Herald

Daly scored twice for Morecambe, on 14 and 68 minutes, as they drew 2-2 with Hereford at the Halo Aerospace Stadium. Hudson and Muir had scored three minutes apart early in the second half to put Hereford ahead. The crowd was 2,114.

Stevenage topped Southern Group B by beating Fulham U21 4-3 on penalties after a 2-2 draw at home. Mellon scored twice for Stevenage, on 22 and 59 minutes, and Works twice for Fulham, on 37 and 79. The crowd was 519.

Notts County went into the knockout stages as winners of Northern Group F with a third win in three EFL Trophy games, beating League One Burton Albion 3-0 at the Pirelli Stadium. Campbell scored on 20 minutes, and Smyth and Sanders added two more in four minutes midway through the second half. The crowd was 1,016.
