All over - great result for the US.

Amazing - corner whipped in from the right and big John Brooks gets up to head it home. Johnson deserves credit in winning the corner.
Ayew finishes superbly after a great backheel from Gyan. Great goal - and exactly what Ghana deserve.
Johnson did well on the right, eventually got the ball to Dempsey whose shot is held by Kwarasey
USA just reversing a second bus in front of goal now.
Asamoah hits a shot from distance - it moves around in the air but the Everton keeper, who has been excellent tonight, catches it clean.
Gyan's shot blocked right in front of goal by Cameron - they are pounding on the door at the moment.
Atsu drfits a shot over the bar. Howard had it covered.
Howard tips a header from Gyan wide - great effort.

Ayew whips a great gross in for Gyan - his header goes over the bar. Should have scored.
Sulley Muntari blasts an effort towards goal from 25 yards - it sails just wide. Getting closer.
Atsu has a shot from distance - nowhere near the goal. Sums up Ghana in an attacking sense so far.
Bit more about Ghana in the second half. Looks like they mean business.
Back up and running.
Mis-hit from Ayew after Atsu had got in loads of space down the right and found him with a pass in the penalty box.
Johansson gets a sight of goal for the US but scuffs his volley.
Ghana have had more possession, corners, shots at goal - but haven't really looked like scoring.
Dempsey has just got a smack in the face. Wow, that hurt...
Howard beats away a shot from Gyan - powerful effort.
Rabiu booked for Ghana
Atsu curls a shot just wide - Ghana teasing and probing on the edge of the area. Looked like there was a foul by Beckermann in there too.
Besler shanks a clearance over his own crossbar.
Bradley plays in Bedoya but his shot from distance is disappointing. US just coming to terms with that bad injury for Altidore.
Altidore looks like he's blown his hamstring. That's very sad to see...
Altidore's shot blocked by a Ghana defender. Decent counter by the US - but the Sunderland striker should have done better.
Ghana starting to settle now and swamping the right side.
Howard had to be really quick off his line to stop Gyan getting in on goal. Great pass from Ayew.
Amazing stuff. according to this story Dempsey's strike is the fifth fastest in World Cup history.
Great bit of skill on the edge of the box to beat the Ghana defender, cool finish. What a start for the USA!
Clint Dempsey scores after 31 seconds!

@MarcIles USA USA USA pity stu not playing. I know my son in new york will be watching to— @bwfc12 16 June 2014
Ghana have got some talent in that team - but I'm going for a narrow US win.
Last game of the night and I'm absolutely sure it will be better than the last one.
