USA camped in Scotland's 22 in these last five minutes. The line-out - despite malfunctioning five times - is solid for now. Knowing a penalty is coming their way, Seamus Kelly goes through the gap... Advantage still with the Americans, so is the ball... until Olive Kilifi botches a simple gather.
Scotland 32-16 USA
We mentioned earlier that the USA gave away a whopping 15 penalties against Samoa last week, and already they've given away 10 again today.
That means, across the 150 minutes of World Cup action they've been involved in so far, they've infringed on average once every six minutes.

USA with a chance to bolster the line-out stats in their favour as AJ MacGinty boots them into the Scottish corner. One successful line-out ticked off.

Scotland 39-16 USA
Despite the 23-point gap, the stats point towards a remarkably close game, in which Scotland just shaded possession but did enjoy much the better territory. Those barnstorming 15 minutes after the break taking the steam out of the Americans.
Full-time
Scotland 39-16
Five tries for the Scots, who were 13-6 adrift at half-time. The replacements the difference between an iffy first half and a confident second half.

And that's our lot. Referee Chris Pollock brings a try-fest of a match to an end and it ended up being a thumping win for the Scots.

Converted try - Weir; Laidlaw con
Scotland 39-16 USA
Richie Gray and Josh Strauss make minor breakthroughs, which Matt Scott tries to take advantage of but he's knocked back. There's no stopping Duncan Weir from 3m out, though, as the replacement holds off one would-be tackler to touch down.
Greig Laidlaw with the easiest of conversions and if feels like eons ago that the USA were once leading this match.
Scotland 32-16 USA
Scotland's Alasdair Strokosch has had a busy afternoon, crunching his way to 14 tackles. Remarkably, despite the scoreline the United States still top the metres made charts - and Scotland the tackles made charts.
Mistakes destroying USA's hopes of a stirring finish, though. Zachary Fenoglio knocking on, gifting Scotland possession in these closing stages.

Team-mates gather around WP Nel to slap him on the back thanks to his thigh-slappingly good work in the scrum to earn a penalty for his team. The Scots surviving a period of sustained USA pressure. Five minutes remaining...

USA camped in Scotland's 22 in these last five minutes. The line-out - despite malfunctioning five times - is solid for now. Knowing a penalty is coming their way, Seamus Kelly goes through the gap... Advantage still with the Americans, so is the ball... until Olive Kilifi botches a simple gather.
Scotland 32-16 USA
We mentioned earlier that the USA gave away a whopping 15 penalties against Samoa last week, and already they've given away 10 again today.
That means, across the 150 minutes of World Cup action they've been involved in so far, they've infringed on average once every six minutes.
Scotland 32-16 USA
USA with a chance to bolster the line-out stats in their favour as AJ MacGinty boots them into the Scottish corner. One successful line-out ticked off.
Scotland penalised. USA opt for touch. Another successful line-out and the white shirts have fire in the bellies... tryline looming... Replacement forward Olive Kilifi held up... Referee spots an American shirt straying. Scotland with the put-in at the scrum, 5m from their own line.
Scotland 32-16 USA
The United States, who lost four line-outs against Samoa a week ago, have lost a further five out of eight against Scotland today. The set-piece really not working too well for the Americans.

Converted try - Scott; Laidlaw con
Scotland 32-16 USA
This drive a tad more difficult for the USA to stop, legally or illegally, Greig Laidlaw barking orders at the ruck and it's Matt Scott who gallops and side-steps at a brilliant angle and touches down.Laidlaw successful with the straightforward conversion in front of the posts.
Scotland 25-16 USA
"Scotland! Scotland!" is the chorus reverberating around Elland Road as they watch their men prepare for another attacking line-out 5m from the USA tryline.
The attempted drive brought down illegally by Al McFarland,says referee Chris Pollock. "You're giving too many penalties away," warns the referee.
Scotland opt for another attacking line-out.

Scotland have pulled nine points clear in this second half but still there's nothing in the attacking stats. The United States lead the metres made column 304-299 and the carries 85-83.

Scotland eager to run with the ball, they've upped the tempo and look the more likely to score. The forwards take them into the USA 22 and it's the backs who do the damage, Sean Maitland strolling over unchallenged and touching down behind the posts. Finn Russell with an easy conversion.

Try - Visser; missed con
Scotland 11-13 USA
Quick line-out ball for the Scots in the American half, which puts the men in blue on the front foot. Finn Russell orchestrating nicely, forwards punching holes, and this time the Scots finish the move, from Stuart Hogg to Tim Visser in the corner. A 10th international try for the winger. Russell wide with the difficult conversion.

Scotland's star man

Penalty - MacGinty

Oof Hayden Smith loses the ball in contact. Bringing a wonderful phase of play to a disappointing conclusion - 15 phases as they battled their way towards the tryline inch by inch.
But the Scots were offside. AJ MacGinty in front of the posts. Easy peasy. Three points to end a fabulously entertaining half.

There's not been much in this first half at all, the United States edging the metres made 210-187 but Scotland having made more carries (47-40).
USA have panache when they run with the ball, the underdogs not lacking in pluck or adventure. They're into the Scottish 22. Cries of "USA!" reverberating around Elland Road.

Scotland add width to the ball, but run out of turn. It isn't quite going the Scots' way in these last 10 minutes. They're huffing and puffing - but the USA's bone-crunching tackles are preventing them from blowing anything down, or even getting into the opposition 22.

A chance for both sides to breathe before Henry Pyrgos puts in at the scrum. Number eight Josh Strauss emerges with the ball, the backline ready to move - but Finn Russell is horozontalised by Seamus Kelly and the outside-half can't get the ball away.
Nevermind. Referee Chris Pollock has spotted a USA player offending and Scotland have put-in at the scrum inside their own half.

What a wonderfully exciting match. Stuart Hogg with the footwork of a salsa dancer, a shuffle of the hips on a magical burst which has the USA defence floundering. Tim Visser is his support man, all he has to do is gather the ball and a try beckons - but the winger fails to gather. Oh my word. What a miss. The tryline was at his mercy.

Scotland have had the better of the possession, the better of the territory, but the United States lead thanks to Titi Lamositele's try.
The Scots are ahead for every attacking stat other than the 'tries for' column.

United States rely upon captain Chris Wyles quite heavily in attack, and already he has made more metres (34) and carries (three) than any other player on the pitch.
Scotland have dominated the possession stats though, having seen 67% of the ball.
Converted try - Lamositele; MacGinty con
Scotland 6-10 USA
What winning your own line-out can do. USA secure ball near the Scottish 22, the forwards punch holes through the Scottish defence... Phillip Thiel with a bulldozing run. Richie Gray holds him off but it would need 30 men to stop prop Titi Lamositele from wriggling under a mass of bodies.
AJ MacGinty's conversion kisses the uprights but falls the right way. Two points. What a surprise this score is.

Magnificent from USA's forwards, stealing possession from a Scottish put-in at the scrum. The men in dark blue fall like a pack of cards. Another put-in for the Scots, though, but Vern Cotton's men penalised for early engagement. Not the finest five minutes for Scotland's forwards.

Penalty - MacGinty

You want to know about the teams? Ah, right. Here you go... Scotland have had just a four-day turnaround since winning their opening match 45-10 against Japan in Gloucester, and so coach Vern Cotter has made nine changes.
Cotter's plans have been somewhat muddied as back-rower John Hardie, who was originally set to keep his place, was ruled out with a head knock.
Ryan Wilson, who was to have dropped to the bench, now retains his place, with Fraser Brown stepping down to start among the replacements, as he did against Japan. The other seven replacements against Japan all start today.
Winger Tim Visser and flanker Alasdair Strokosch, who were not involved at all on Wednesday, also start.
