Kieffer Moore's header looked in all the way, he just got slightly too much on it.

How Wales must wish he'd been on from the start, he's totally transformed the contest.

Anywhere to the side of that goalkeeper and that [Ben Davies header] would have been in. Great save though.

Brenden Aaronson of Leeds is on for Weston McKennie.

Double chance for Wales!

First Arsenal deny Tottenham.

Ben Davies' header is really well saved by Matt Turner who tips the ball over.

Then Kieffer Moore heads over with Turner beaten from the corner.

Should be 1-1.

Suddenly it is the USA who can't get out of their own half.

Yunus Musah smashes into Connor Roberts.

Another Wales freekick.

They need to find a good delivery.

Great challenge Connor Roberts! A last-ditch tackle denies Christian Pulisic.

Wales on top for the first time in the match.

Can they capitalise?

Kieffer Moore has been great since he's come on, he's just an outlet for us and a successful outlet.

Much better from Wales, concerted pressure in fact, but then a really poor cross from Connor Roberts.

Wales' wing-backs have stepped up 20-yards and it is making a huge difference.

Kieffer Moore's introduction hasn't just meant Wales can now hold the ball up and advance up the pitch.

The Red Wall have just bellowed out his name (to the tune of KC & the Sunshine Band's 'Give it Up') and let's face it, they weren't given much else to sing about before he came off the bench.

When we put a little bit of pressure on USA, we get the ball back.

Aaron Ramsey almost releases Harry Wilson.

There were some similarities there to the first half of last year's Euros opener against Switzerland - but quite a lot worse.

Robert Page somehow has to try and fix the Welsh midfield, and has brought on Kieffer Moore, who scored the equaliser against Switzerland.

Neco Williams is the danger man.

Sergino Dest has been booked and Timothy Weah doesn't do much back-tracking.

Williams has acres of space on the left. Wales need to exploit the space.

Already we have gained momentum in this second half, just doing the very basic things, running the channels, holding the ball, a good transition moment between Aaron Ramsey and Gareth Bale and already the momentum has shifted.

Much more of a contest now.

Tim Ream with a cynical pull on Gareth Bale.

3-2 to the USA on yellow cards.

Matt Turner is grateful for a lucky free-kick after he flapped at a corner.

Defending suddenly looks less comfortable for USA.

Wales' energy levels already look better.

Are they playing the old Antonio Conte 'start in the second half' game?

Encouraging.

Wales find Kieffer Moore and he makes the ball stick.

Can he bring Gareth Bale or Harry Wilson into the game?
