If it stays as it is then Portsmouth will have their promotion to the Championship confirmed.
They showed good character to get back into the game after going behind, but since Kusini Yengi's powerful strike neither side have dominated.
Barnsley have looked dangerous on the counter-attack with Will Norris called into action a few times.
Fratton Park getting a touch nervous in moments, a big 45 minutes still to play.
HALF-TIME
Burton 1-0 Cheltenham
A late, late goal in first-half stoppage time by loanee Steve Seddon has given Burton's survival hopes a huge boost.
But it's a shocker for Cheltenham whose League One status hangs by a thread.
The goal also means as it stands Fleetwood are releagted.
HALF-TIME
Portsmouth 1-1 Barnsley
So far so good for Portsmouth, who need a point to go up as champions.
Devante Cole didn't read the script when he put Barnsley ahead after just six minutes.
But only three minutes later Kusini Yengi equalised and as it stands, Pompey are heading for the Championship.
HALF-TIME
Notts County 0-3 Stockport
Stockport have come flying out of the blocks at Meadow Lane and have caught their opponents off guard.
Paddy Madden's hat-trick takes the headlines so far, but Dave Challinor's side are very much on their way to being crowned champions.

The two sides are starting to cancel each other out here at Fratton Park.
This game is as tight as we expected it.
HALF-TIME
Colchester 1-0 Grimsby
Colchester are four points clear of the relegation zone in League Two.
The only disappointment will be that Danny Cowley's side are not further clear of the visitors, having dominated possession.
GOAL: Burton 1-0 Cheltenham
Steve Seddon (45+4 mins)
Eight minutes of stoppage time at Burton after a couple of injuries.
And the home side have used it well to take a huge lead.
A long throw from the right evades everyone and falls for Steve Seddon at the back post who fires home with a left boot.
HALF-TIME
Bolton 1-2 Shrewsbury
A surprise scoreline here.
Daniel Udoh gave Shrewbury the lead mid-way through the half and it was almost two from Chey Dunckley's header.
Cameron Jerome scrambled in an equaliser but shortly after, a screamer from Jordan Shipley has put the Shrews back in front.

The evening started with high expectations at the One Call Stadium, but the Stags were doing all they could not to get over excited about the occasion.
That early George Maris opener, which may end up going down as a Tommy Leigh own goal, has had the home fans in a state of euphoria from the get go.
They have had numerous half-chances to add to their lead, but it remains a slender advantage right now.
Notts County 'not doing things with much venom.'
Notts County 0-3 Stockport
Sam Minihan
former Stockport defender on BBC Manchester
What has been the undoing for Notts County is that they are not doing things with much venom.
It is just the intensity, the movement of the ball, the finer details that is lacking.
It is a clear style of play they have, the passing out from the back, the aggressive high positions, but it is not working for them yet.

Bristol Rovers ended a seven-match scoring
drought with a 3-1 win over Cheltenham at the weekend but hitting the back of the net is proving a problem once again tonight.
Their 15-goal top scorer Chris Martin has the chance to put his side ahead at home to Cambridge from the penalty spot but Will Mannion makes the save!
GOAL: Bolton 1-2 Shrewsbury
Jordan Shipley (43 mins)
What a hit! Shrewsbury back in front!
A corner from the right is floated low to the top of the area and met by Jordan Shipley.
He meets it left footed and rifles his shot through a crowd of bodies and the power is too much for Nathan Baxter to keep out.
GOAL: Notts County 0-3 Stockport
Paddy Madden (40 mins)
Think it may just be Paddy Madden's day.
Antoni Sarcevic delivers the ball in from the right wing and Madden - in confident mood from his two earlier goals - decides to shoot quickly.
The ball deflects over the goalkeeper and into the net.
GOAL: Bolton 1-1 Shrewsbury
Cameron Jerome (40 mins)
But now Bolton are level!
It's a terrible goal but they won't care.
A corner from the left isn't dealt with, it bobbles around and falls at the feet of Cameron Jerome inside the six-yard box.
Jerome is able to turn and slap it into the net.

Barrow's Emile Acquah has put his side ahead against Crawley with a towering header!
The cross is floated in and Acquah drifts into space and plants a wonderful header low into the corner.
If Barrow win tonight that will more or less seal a play-off spot but Crawley are very much looking over their shoulder at a host of teams below them now.

Dave Bracegirdle
BBC Radio Nottingham commentator
Notts County have conceded their 16th penalty this season.
It looks harsh to me.
It is inconclusive whether it even hits his arm.
Dan Crowley has no time to react, it sort of hits him.
No chance of saving that emphatic penalty, double quick salvo from the boys from Cheshire.
GOAL: Notts County 0-2 Stockport
Paddy Madden (33 mins)
Paddy Madden at the double!
He buries the penalty kick to extend the league leaders advantage at Meadow Lane.
