Sam Dalby can't quite get onto the end of a whipped ball into the Oldham box from Paul Mullin.

The two Wrexham goalscorers can't quite combine this time, however.

Meanwhile, amid some more pressure from the hosts, Elliot Lee sees a shot inside the box blocked.

It's a brilliant striker's goal because he reads it off the flick.

The long throw came in, it wasn't necessarily a Wrexham player who wins it, but Paul Mullin reads where it's going to land and all he had to do was redirect it into the back of the next.

Wrexham are so strong from corners and long throws, they score from open play as well. They have goals from all angles.

Television replays show he was just onside, however.

Wrexham fortunate there as Fondop was well placed.

As we said earlier, we're already a game down in today's FA Cup ties.

National League Woking's FA Cup tie against League One side Oxford United has been postponed because of a waterlogged pitch. It was due to kick-off in 10 minutes' time.

The game was called off on Sunday morning following an inspection at Woking's Laithwaite Community Stadium after heavy overnight rain.

A new date for the first-round tie has yet to be confirmed.

"The competition deserves games that are played in the right conditions," said Oxford manager Karl Robinson.

"Some of our staff were already at the ground and saw the pitch for themselves, the rest of us and the players were making our way there but the decision was made early enough for us to turn round and report to the training centre and prepare for Wednesday night's game at Shrewsbury."

I said at half-time that Oldham needed to play football in Wrexham's half and they've done that much better.

They've asked questions of Wrexham, which they didn't do in the first half.

Nathan Sheron puts a ball in towards Timmy Abraham who heads directly at Wrexham keeper Mark Howard.

And here's how the two sides line-up in that tie...

The largest gap between any of the teams competing in today's FA Cup fixtures is between Curzon Ashton of the National League North and League One Cambridge.

They are separated by 69 places in the football pyramid but The Nash might fancy their chances of an upset considering The U's less than spectacular league form.

Adam Lakeland's side sit 17th in the National League North but have the threat of striker Tom Peers, who has 10 goals this season, allied with the joint-best defensive record in the league.

This is Curzon Ashton's third appearance in the FA Cup proper and they have reached the second round in both of their previous campaigns (2008-09 and 2016-17).

Cambridge were giant killers themselves last season, knocking out Premier League Newcastle United in the third round, and will be keen to avoid being the victim this time around.

It could be an awkward afternoon for Mark Bonner's charges, who are currently 18th in League One after losing six of their last seven league games.

Oldham substitute Mike Fondop gets in the mix early in this second half.

Timmy Abraham tees him up inside the Wrexham box but Callum McFadzean immediately puts the block in to deny him.

We're back under way at the Racecourse Ground.

I think Oldham have got to go for it now, they can't sit back. If they're serious about getting a result today they have got to come out of the traps and pose Wrexham problems.

If they can get a goal in the first 20 minutes then it's game on as Wrexham are notorious for having a wobble in 20-minute spells at home.

Can they make it tough for Wrexham in the second half?

I don't think Oldham have really got going and that's partly down to the way Wrexham have played, they've not given them any real possession in any part of the pitch that has hurt them.

Wrexham have kept the ball well, got the early goal that has allowed them to go out and play.

Luke Young has dictated things, they've looked really comfortable and that second goal was the icing on the cake.

Sam Dalby and Paul Mullin's goals for Wrexham are the tale of the first half against Oldham.

Work to do for the visitors if they are to avoid being knocked out at the first round stage.

Three minutes added on in the first half, presumably due to the injury to Anthony Forde.

Can either side make that time count?

Charlie Cooper goes into the book for a foul on Callum McFadzean.

Not much longer to go in this first half now.

Callum McFadzean just about deals with a Timmy Abraham cross into the Wrexham box and the hosts break on the counter.

Elliot Lee tries his luck from long range but Lois Maynard blocks while soon after Luke Young fires wide.

Bryce Hosannah coming in is like for like. He will be looking to make his claim to stay in the team.

Everyone who comes into this team has to have that attitude to take that jersey off the person who is in control of it.

Wrexham are forced into an early change.

Anthony Forde goes down and receives some treatment but he's eventually replaced by Bryce Hosannah.

Timmy Abraham, who recently joined Oldham on loan from Walsall, wins a corner for the Latics.

It's headed clear by Wrexham but into the path of Mark Kitching who buries a half volley over the bar.
