Stevenage manager Steve Evans says his side will not give up the fight for a Sky Bet League One play-off place despite going down to a 1-0 defeat at Exeter.

An error by goalkeeper Taye Ashby-Hammond, who saw his clearance charged down by Exeter striker Sonny Cox and finished off by Reece Cole, led to the only goal of the game and the defeat leaves Evans’ men six points adrift of the play-off places with four games remaining.

“It’s a harsh result,” he said. “The goalkeeper has made a huge error, he got away with it twice with a lack of focus, lack of concentration. He’s been very good for us, but that wasn’t his normal self today.

“We are chasing the game then, but we create wonderful chances. (Alex) McDonald is through one-on-one and puts it in the keeper’s arms; Jamie Reid, who has been phenomenal for us, misses what you’d call a simple header and we have had two or three off the line.

“We have dominated the whole second half and it is disappointing, but it is not just today where we have dropped out of the play-off race, it’s been over four or five weeks because if you don’t score goals, you don’t win football matches.

“Football is a strange game and if someone had said to me when I joined this football club two years ago we will be five games from the end of season at Exeter and disappointed not to put yourself back in the play-off group in League One, you’d have thought you’re in dreamland. But when you have achieved something, you always want more.”

Exeter boss Gary Caldwell was delighted as his side moved into the top half and, with 54 points, they are all but certain of playing League One football again next season when things looked much bleaker for the Grecians just before Christmas.

“It takes time and fortunately, this football club understands that because this season has not been a linear process, there have been highs and lows and I think if you give people who are working extremely hard the time to make it happen, then you can see the results,” Caldwell said.

“I did my pro licence with Steve Evans, I know how competitive he is, how many promotions he has won and he always builds successful teams and they have had an incredible season.

“We knew we were in for a tough day and had to stand up to their physicality and they are pushing for a lot in terms of what they can achieve this campaign, but I thought we stood up to it and our character, our determination and our team spirit was incredible.

“But we have to be better. There are areas of our game where we have to improve and recognise where the space is, where the free player is. But to be able to do that from a winning position is far better than losing, so full credit to the players for that.”

Louie Sibley’s last-minute winner gave Derby a 1-0 home victory over stubborn Stevenage to boost their automatic promotion hopes in League One.

With top scorer James Collins out with a knee injury, Derby lacked a presence up front but Sibley finally found a way through in the last minute of normal time.

The victory moved Derby three points clear of third-placed Bolton.

It was Stevenage who came closest to scoring in a goalless first half.

Joe Wildsmith missed a corner and Sonny Bradley had to clear off the line in the 31st minute and Wildsmith rescued Derby soon after when the hosts failed to deal with a long throw and the goalkeeper stopped Jordan Roberts’ shot on the turn.

Derby did not register a shot on goal in the first half and they continued to struggle until Kane Wilson surged forward in the 68th minute and played Nathaniel Mendez-Laing in but he fired wide.

Max Bird was denied by a superb Taye Ashby-Hammond save in the 77th minute but Derby struck late on.

Mendez-Laing cut in from the right and set up Sibley who finished first time from 12 yards.

Goalkeeper Taye Ashby-Hammond was the hero as Stevenage secured their place in the third round of the FA Cup with a 4-3 penalty shoot-out victory at Port Vale.

After a 1-1 draw at Boro last time, another 120 minutes could not separate the two sides in the replay at Vale Park as they drew 3-3 after extra time.

Ben Garrity scored either side of half-time to put Andy Crosby’s hosts two goals ahead.

He opened the scoring after just six minutes as he tapped home from close range before he hammered in a second after Alfie Devine nodded a cross into his path 10 minutes after the restart.

Harvey White’s unstoppable near-post strike pulled one back before Kane Hemmings sent the game to extra time in the sixth minute of additional time.

Ryan Loft’s first goal for the club, in the 114th minute, again seemingly sent Vale through before Nathan Thompson sent the game to penalties.

It was then a painful penalty shoot-out for the hosts as scorers Garrity and Loft saw their spot-kicks saved by an inspired Ashby-Hammond, either side of Luther Wildin smashing his over.

Steve Evans’ side now have a trip to non-league Maidstone, who are playing in the third round for the first time since they reformed in 1992.

Dino Maamria was sacked as Burton manager following his side’s 2-1 defeat to promotion-chasing Stevenage.

Deji Oshilaja gave Albion a seventh-minute lead, converting the rebound after Joe Powell’s penalty was saved by Taye Ashby-Hammond.

But Kane Hemmings struck against his former side on the stroke of half-time and Jamie Reid kept his cool from the penalty spot to condemn Burton to a fifth defeat in six winless games in League One.

That run has seen Burton slip down the table, with Maamria leaving them in 19th place, four points above the relegation zone.

A statement from chairman Ben Robinson read: “Dino Maamria has been relieved of his first-team duties with immediate effect.”

Maamria performed his post-match media duties but was in sombre and reflective mood of not only the game but his time at the club before learning of his departure.

“I thought we started well in very tough conditions,” Maamria said.

“We dealt with a number of long balls and then went ahead, deservedly, I thought and then last minute of the half we switch off at the back post and then they score to go in at half time one-one.

“Second goal it comes from a poor throw out and their players pick it up. KB (Kwadwo Baah) is trying to get back in position but they get a penalty.

“It is tough to take. Ultimately I have been at this club two weeks short of three years and I have loved my time here. I think the fans have been magnificent with me throughout that time, a lot of players and a lot of staff.

“It is a winning business and I haven’t won enough games. We had a good October but overall I understand the fans frustrations. Football is a winning business and we didn’t win today.”

Stevenage boss Steve Evans hailed his side as they maintained their League One promotion push.

Evans, whose team are third, said: “It was an outstanding performance. Maybe we were still trying to deal with the conditions in the first 10 minutes and we were a bit sloppy leading to them getting the penalty.

“We had a perfectly good goal disallowed with one that was over the line, having seen the footage and the stills, but in fairness to the referee there were a lot of bodies in the way but then you look to the assistant, so we felt a bit hard done to.

“I thought we became really strong in the last 20 minutes before half-time, got the goal, and perhaps we should be turning round in front, despite the penalty and then, I think, second half, we controlled it. It was inventive and it was bright.

“For 70 minutes, how could you not be commending that sort of performance and we come away with a very hard fought and deserved three points.”

Chris Martin scored his first goal for Bristol Rovers as he chipped in from 35 yards to earn a point for the home side in a 1-1 draw with Stevenage.

The 34-year-old elegantly lobbed over stranded goalkeeper Taye Ashby-Hammond with seven minutes remaining when John Marquis fed the ball to the Pirates’ September free transfer signing.

Stevenage striker Jamie Reid had netted his ninth goal of the League One season before that as the visitors took the lead in the 40th minute.

Kane Hemmings, Connor Taylor and goalkeeper Matthew Cox all collided in the area trying to meet Jordan Roberts’ looping cross, and while the home supporters awaited a whistle from referee Matthew Donohue, it never came. Instead Reid gathered the loose ball and calmly slotted into the open goal.

Rovers forward Jevani Brown saw a good effort blocked in the second half, while Carl Piergianni headed a Jake Forster-Caskey free-kick against the post with half an hour to play but Stevenage came no closer to scoring.
