Top-of-the-league Sunderland extended their perfect start to the season as they beat Portsmouth 3-1 at Fratton Park to secure their fourth Championship victory in as many matches.

The visitors went ahead 31 minutes into the match through a Zak Swanson own goal and never looked back.

It was an unfortunate moment for Swanson, who was in the wrong place at the wrong time when team-mate Jordan Williams’ clearance rebounded off him into the goal.

Republic of Ireland international Alan Browne added a second - his first since signing for Sunderland in the summer transfer window - six minutes into the second half, before Romaine Mundle made it 3-0 and killed the game as a contest in the 56th minute.

Portsmouth made four substitutions on the hour, including the introduction of deadline-day signing Mark O’Mahoney, but none were able to get their team back into the match.

The hosts managed just one shot on target before Luke O’Nien’s stoppage-time own goal gave them a consolation. They await their first victory of the campaign and sit 18th in the table.

Oxford United went up alongside Portsmouth, but enjoyed their afternoon a little more as they came from behind to beat Preston North End 3-1 at the Kassam Stadium.

It was a first defeat for Preston manager Paul Heckingbottom, who was appointed manager earlier in the month after Ryan Lowe was sacked.

The visitors started better, with Emil Riis Jakobsen opening the scoring after just three minutes. But in-form Mark Harris levelled after 20 minutes with a header as he scored for the fourth straight league game.

It was to get even better for Oxford in the second half when Tyler Goodrham put them into the lead with a spectacular strike. Preston were then reduced to 10 men, with Liam Lindsay picking up a second booking in the 70th minute, and Greg Leigh wrapped up the points a minute later.

The win takes Oxford to eighth, while Preston are in 21st, one place below Sheffield Wednesday who were beaten 3-0 by Millwall at the New Den.

Josh Coburn scored on his debut for the hosts in the second half, before goals from Duncan Watmore and Jake Cooper secured Millwall’s first win of the season. For Wednesday, it’s now three straight defeats.

Unbeaten Leeds United went fourth in the table following a 2-0 victory over Hull City, who sit 19th and are still waiting for their first victory of the campaign.

Second-half goals from Mateo Joseph and Joel Piroe at Elland Road helped Leeds secure back-to-back victories for the first time this season.

Barnsley head coach Neill Collins was left frustrated as his promotion-chasing side were held to a 0-0 draw by League One strugglers Cheltenham.

The Tykes had numerous chances to break the deadlock but could not find a way through a resilient Cheltenham side who are fighting for survival.

The draw prevented Barnsley from moving up to fourth and they now sit seven points behind the automatic promotion places.

Collins said: “I don’t think the players did an awful lot wrong. We’re really frustrated because obviously it’s a game at home that we expect to win.

“It felt right up until the 96th minute that we could score.

“It’s hard to be too critical because I think on another day we get that first goal and we go on and win the game.

“(We’ve got) a couple of lessons to learn. We’re all frustrated but I think what probably makes it feel worse is we just had that disappointment here last week (a 5-1 home defeat to Lincoln) and we wanted to put it right today.”

On regular captain Jordan Williams dropping to the bench, Collins said: “Jordan’s played more football than anyone in our team.

“I felt today we needed the extra height at the back to deal with aerial balls. Then (at) right wing-back, I felt Corey (O’Keefe) deserved the opportunity because I think he’s been good.”

Cheltenham head coach Darrell Clarke was pleased with the result, which edged his side to within four points of safety.

“Clean sheet, point at a tough, top-six team to come up against,” Clarke said.

“They ask you a lot of questions in different variations of the game and we defended our box well at times. We had a couple of opportunities as well.

“We’ve had a lot of illness, a lot of injury in the camp and the boys dug in well to gain that point.

“It wasn’t pretty on the eye at times. We didn’t have enough control, for me.

“We had to dig in, we had to defend. But like I said, the lads are putting their bodies on the line.

“The lads were on their last legs at the end there.

“We huffed and we puffed, couldn’t quite get that goal but a clean sheet away at Barnsley, against a team that scores a lot of goals is pleasing.”

Clarke picked out the performance of 39-year-old defender Curtis Davies.

“That experience in the backline helps us at times just to settle things down,” Clarke added.

“I’ve forgotten the amount of balls he headed out the six-yard-box for us, which is why he’s in there and he’s important for us. A great lad.”

Barnsley boss Neill Collins praised his side’s reaction from their weekend mauling as they came from a goal down to beat Carlisle 3-2.

Question marks were raised about the Tykes’ promotion credentials after they were hammered 5-1 by Lincoln on Saturday.

But, despite falling behind to Luke Armstrong’s early goal, they equalled a club record of 10 successive away games unbeaten in the same season.

Goals from captain Jordan Williams, John McAtee and Jonathan Russell put them in command and they held on for all three points after Daniel Butterworth pulled one back for League One’s bottom club Carlisle.

And Collins said: “That’s a huge win and in some respects our biggest win of the season.

“We are on a great run, but despite all of the positives, one performance gets questions asked and I thought the players answered them well.

“It’s fantastic to get a big record like that at a club like Barnsley who have had a lot of good teams over the years.

“One mistake and it was a goal and in the back of the net, but after that we were really good.

“We could have been ahead at half-time but we came out and continued and really could have had more.

“There was another mistake at the end and that made it a bit more interesting than I would have liked.”

Williams produced a fine 20-yard strike to level in the 33rd minute.

Collins added: “It was fantastic. Jordan has been an excellent captain and got a great goal. For large parts his performance was excellent.”

Paul Simpson’s Carlisle have lost 11 of their last 12 as relegation straight back to League Two creeps ever closer.

They are now 16 points adrift of safety and Simpson said: “You have to be brutally honest, they were the better team.

“When you look at the levels, you’ve got a team who have been in the Championship and fighting for promotion and we’re where we are because that’s where we deserve to be.

“That’s clear to see in terms of the technical ability of them and the care they took on the passing.

“We had opportunities where we got into the final third, but we don’t take enough care on it.

“The disappointing thing is we work day in and day out on passing and possession drills. We get in good areas, but can’t do it.

“I’ve said to the players that it’s an education. We’re seeing and we’re suffering because we’re coming up against teams who are physically stronger and that’s not a case of just working on it in the gym, they’re psychologically made up better than us.

“That’s something we’ve got to change because we’re aspiring to be like that as a football club.

“We want to improve and be able to compete at this level, but currently we’re a long way off it.”

Barnsley got back to winning ways as they held on for a 3-2 victory at League One bottom club Carlisle.

Neill Collins’ promotion-chasing side were hammered 5-1 by Lincoln on Saturday and it looked like they may have been suffering a hangover when Carlisle took an early lead through Luke Armstrong.

But Jordan Williams, John McAtee and Jonathan Russell all scored for the visitors before Daniel Butterworth set up a tense finish.

Armstrong started the scoring when he grabbed his second goal in as many games in the 10th minute.

Captain Williams produced a fine 20-yard strike to level in the 33rd minute.

McAtee rattled the crossbar minutes later before Sam Cosgrove forced Carlisle goalkeeper Harry Lewis into a good stop to tip his powerful strike over.

After the break, McAtee poked home the second after Cosgrove dinked the ball over Lewis.

Towering Russell got the third when he nodded home Corey O’Keeffe’s cross at the back post with 14 minutes left.

Butterworth pulled one back with three minutes to go but Barnsley held on for the points as Paul Simpson’s strugglers lost for the 11th time in their last 12 league outings.

Derby ended Barnsley’s unbeaten away run in League One as James Collins scored twice in a 3-0 win.

Collins fired in a first-half penalty and struck again after Craig Forsyth scored to condemn Barnsley to their first defeat on the road this season.

Derby started strongly with Nathaniel Mendez-Laing causing problems on the left although Joe Wildsmith had to turn behind an Adam Phillips free-kick in the 21st minute.

But Derby went ahead in the 35th minute when Jordan Williams pushed over Collins to concede a penalty which the striker confidently converted.

Derby were worth their lead and they extended it in the 48th minute with Forsyth ghosting in to score with a low finish after a long free-kick was flicked on.

A repeat of that move brought Derby a third in the 63rd minute with Forsyth again getting in on the left to fire in a shot which Ben Killip saved but Collins bundled in the rebound.

Tom Barkhuizen fired over and Louie Sibley rattled the bar as Derby enjoyed a comprehensive victory.

Oxford made it three wins on the trot in League One after beating Barnsley 3-1 at Oakwell.

Cameron Brannagan scored an early penalty to put Oxford in front and Jordan Williams’ own goal made it 2-0 just before the hour.

Devante Cole pulled a goal back for Barnsley with 20 minutes left but Tyler Goodrham sealed the points for the improving visitors late on.

Oxford, who started the season with a 2-0 defeat at Cambridge followed by a 5-1 Carabao Cup mauling by Bristol City, came into the game on the back of wins over Carlisle and Derby and they needed just eight minutes to take the lead here.

Marcus Browne was fouled by Mael de Gevigney inside the area and Brannagan slotted home from the spot.

Barnsley went in search of an equaliser but Andy Dallas skewed his shot off-target from a great position and Nicky Cadden fired just over.

Oxford also had their chances and Mark Harris and Stanley Mills both shot straight at Liam Roberts in the Barnsley goal before Adam Phillips was denied by James Beadle at the other end.

Oxford increased their lead 10 minutes after the re-start. Mills made a surging run down the right, reached the byline and sent over a low cross which Williams attempted to clear but succeeded only in turning the ball into his own net.

Barnsley were given a lifeline in the 70th minute when Cole pulled a goal back with a header from a Cadden corner but Goodrham ensured it would be Oxford celebrating the win after being set up by Gatlin O’Donkor.
