Sonny Bradley’s brace kept Derby on course for automatic promotion as they claimed a 3-0 win over Leyton Orient.

The Rams got the start they needed in the 10th minute when Kane Wilson tapped in at the back post from a Nathaniel Mendez-Laing corner.

It got even better for the home side eight minutes later when a Louie Sibley corner dropped to Bradley and he fired into the roof of the net.

Orient hardly figured as an attacking threat until Ethan Galbraith had a shot blocked at the end of a first half which had been all Derby.

Shaq Forde had a shot deflected over at the start of the second half but Mendez-Laing went close to a third for Derby with a flick that went narrowly over.

Mendez-Laing had a great chance to finish the game in the 61st minute when he raced clear but a heavy touch allowed goalkeeper Sol Brynn to deny him.

But Bradley made no mistake from another corner in the 86th minute with a bullet header at the back post.

Darrell Clarke admitted it had been a frustrating afternoon for the visitors after his Cheltenham side suffered a 3-1 defeat at Leyton Orient to leave them two points from safety in the Sky Bet League One relegation zone.

Ethan Galbraith and Ollie O’Neill left the visitors chasing the game with first-half goals before Orient’s leading scorer Ruel Sotiriou ended his nine-match barren run with a superb strike late on.

Substitute Joe Nuttall reduced the deficit with a goal in the final minute of stoppage time but Clarke was left to ponder the uphill struggle ahead if his team are to avoid the drop.

“We started the game quite well, particularly in the first 20 minutes, but then we conceded two goals from outside the box that really we could have done better by getting closer at the edge of the box and blocking the shots,” Clarke said.

“I was frustrated at half-time and looking for solutions to the problems we had in the first half and try to get the next goal because the game is not over at 2-0. I think if we had taken our chances and got that next goal, we would have kicked on. It’s all ifs, buts and maybes and now we have to go again.

“Probably the last two or three games have been 45-minute performances and we need to start putting 90-minute performances together.

“I’ve just said to the players, ‘we’re still in this race’, we kept going to the end and I believe there is enough in there to keep us in this division, albeit not on today’s showing.

“I will make sure I get the right answers for the team but we will have to perform better than we did today.”

O’s boss Richie Wellens saw his side collect maximum points at home for the first time in four matches.

“We missed the easier chances today with a couple of one-on-ones and could have scored a few more goals but we also scored three excellent finishes,” he said.

“I thought the keeper should have saved Galbraith’s goal but O’Neill’s goal was good and so was Sotiriou’s. I wasn’t happy with him to be honest because he was a bit sulky and his reactions weren’t great but I know he has a goal in him.

“That game should have been more comfortable than it was but we lacked discipline and gave opportunities away. They could have scored four goals today. I was disappointed we conceded to the one at the end because we wanted the clean sheet.

“This is the first game we’ve played when we can’t achieve anything but we respect the league and the teams fighting, so we played a strong team as well as given Zech Obiero a start at 18 years old, so overall it was a good day.”

Leyton Orient found their shooting boots to inflict a 3-1 Sky Bet League One defeat on relegation-haunted Cheltenham.

A dull opening period was lifted in the 34th minute by a superb Ethan Galbraith strike. Collecting a pass from George Moncur, he drilled a 25-yard drive past the despairing dive of goalkeeper Luke Southwood.

The visitors, who showed little going forward before the interval and failed to record a shot on target in the first half, fell further behind 10 minutes later. Ollie O’Neill, always a threat to the Robins, cut inside from the left and delivered a sublime shot that curled into the far corner.

Finding more purpose after the interval, Cheltenham soon squandered a marvellous opportunity to reduce the deficit when O’s stopper Sol Brynn dropped a set-piece at the feet of Curtis Davies, who managed to screw the ball wide from four yards out.

Ruel Sotiriou completed the visitors’ miserable afternoon in the 85th minute when he pounced from 18 yards out to notch his 11th league goal of the season before Joe Nuttall bagged a late consolation for the Robins.

Boss Shaun Maloney admitted Jason Kerr’s late header against 10-man Leyton Orient secured a ‘really important win’ for Wigan.

The Scottish centre-back had only been on the pitch for a matter of seconds when he headed home a cross from Jonny Smith – who had also come on in the same substitution – to break the deadlock at the DW Stadium.

The O’s had played the majority of the game with 10 men after Ethan Galbraith was shown a second yellow card on 42 minutes after two fouls in the space of 13 minutes on his Northern Ireland international colleague Jordan Jones.

After that it was pretty much attack against defence, with Kerr giving Wigan a victory they undoubtedly deserved.

“It was a really important win,” acknowledged Maloney. “The game obviously completely changed on the red card.

“Leyton Orient were good at times in the first half, we were okay. At times we were really creative, at other times we weren’t at our fluent best.

“The only positive from that was when Leyton Orient had possession I never felt like they were creating big opportunities to score.

“The second half was all about trying to stay patient, understand how we were going to break them down.

“They went straight to a five and a four and it isn’t easy trying to break down 10 men.

“It was hard for the players and every substitution we made was to become even more attacking.

“But I thought the players were really good because it certainly wasn’t easy for them.

“As you can see the winner came from a short corner and sometimes you need set-plays like that to get over the line.”

Orient manager Richie Wellens was pleased with what he saw, having had ‘no complaints’ about the match-changing decision.

“I can’t really remember the first (yellow) but I’ve got no complaints about the second one, his foot was high and it was a fair booking,” he said.

“Until the sending off we dominated the game.

“It was too easy for us, the only threat they had was when we lost the ball in the middle of the pitch and they countered on us.

“I’m very proud of the team – to come to this stadium against a club that win the league whenever they are in League One.

“Wigan should be right at the top end of this division so to come here with really young players and play the way we did was excellent.

“It was comfortable for us at the back, I didn’t think they caused us any problems until they made a good substitution, taking (Charlie) Goode off and bringing on someone who was better on the ball at the back, which caused us problems.

“But we’ve been done by a set-play and we’ve got to be better with that.

“After that, they managed the game well, the referee allowed them to slow the game down, waste time, which you expect the opposition to do in that position.”
