Decent drives from all four players down the 15th. How's your approach game?

Nelly Korda and Nanna Koertsz Madsen find the putting surface but have lengthy birdie putts. Ally Ewing is short and left and down in a hollow.

Madelene Sagstrom is closest, about 15 feet from the pin, but she's going to be chipping out of rough.

A pair of birdies for Carlota Ciganda and Sophia Popov on the par-five 13th hole.

The pressure now on the American duo but Lizette Salas comes up trumps with a four. Still delicately poised.

To add to the drama of this top match, they are also on the clock for slow play.

Is it stirring it too much to suggest that Madelene Sagstrom was aware of that and was just trying to hurry the game along...

Anyway, to the 15th tee... Europe need to retain their composure here.

As you were on the 11th and it is looking that way on the 12th, where Matilda Castren and Lexi Thompson exchange birdies.

While all that has been going on, the players at the centre of hang-gate have been working their way down the 14th hole.

It's eventually halved in par fours.

It turns out that Nelly Korda, whose putt stayed on the green, did not complain about Madelene Sagstrom picking up her ball.

It was the match referee who decided to intervene, telling Sagstrom that she only let the ball stay for seven seconds, when she should have left it for 10. You can bet she'll be waiting a lot longer before she concedes anything for the rest of this tournament.

The Solheim Cup's chief referee has looked at the incident on television and deemed that the ball was overhanging the hole and Madelene Sagstrom picked it up too early.

Therefore, the US win the hole. Nothing more to see here. (Although I guarantee that will be first question asked of both captains post-round.)

Georgia Hall pops a fabulous approach onto the green and pops in a confident birdie to win the tenth.

Team Europe needed that because things seemed to get away from them very fast towards the end of the frint nine.

Is this the start if something for the final foursome?

There's controversey on the 13th. A rules official is claiming that because Madelene Sagstrom picked up Nelly Korda's ball before 10 seconds had elapsed, Korda is going to be given a three and that means the US will be given that hole.

There is a heated debate going on. Catriona Matthew, Europe captain is getting involved.

After Matthew's intervention, the referee agrees to take a look at television evidence.

Sagstrom definitely picked up the ball before 10 seconds had elapsed. The big question seems to be was the ball overhanging the hole and could therefore have dropped?

As it currently stands, the US have been given the hole. The TV footage has to provide evidence to overturn the referee's ruling.

First pumps and plenty of excitement flowing from Carlota Ciganda and Sophia Popov as they march off the 12th green.

Still tied thanks to the Spaniard draining a putt to halve the hole.

Nelly Korda reaches the par-five 13th in two and has a good look at an eagle. She sets the ball off about three yards to the right of the hole and watches as it curls back towards the cup. This is in. No! An inch short.

Madelene Sagstrom nips in to pick up the concession before the ball has time to oscilate in the breeze and drop in. Smart move.

Nanna Koertsz Madsen then has an eagle look of her own. She was pin-high in two, 15 feet to the left of the hole. Her effort dribbles a foot by. "That's good," says Korda. We move on.

Hit it. Hit it. That's three iron shots screeching up short on the 11th.

Some long birdie putts incoming.

Matilda Castren getting a ruling on the 10th with her ball buried in the thick stuff to the right of the green.

She's next to a stream and looks as though she could topple over into it with the stance she is adopting. This is awks.

Some shot that though. It looked like a wrist snapper (you know what I mean amateur golfers) but she whips her club face through and lofts her ball on to the putting surface.

She needn't have bothered mind. Anna Nordqvist sets up a birdie with a glorious shot from a fairway bunker and the European pair are three up.

Team USA have won the last three holes in this foursome, coming into the turn, and the woman of the moment, Yealimi Noh looks at a mean looking downhill putt for a birdie to win a fourth hole on the trot.

It had legs! Just rolls past and perhaps Team Europe breathe a bit of a sigh of relief as the deficit stays to just one hole as they head towards the back nine.

Jennifer Kupcho drained a tramliner from a different postcode earlier, but can't convert here from close range to go in front and these too are locked together at all square.

Still can't separate these two as Madsen has a lengthy putt that snakes its way across the green with two sets of break but just pulls up short.

From there, all the remaining putts are conceded and they walk off to the 13th still all square.

Mina Harigae strikes a marvellous approach shot that rolls tantalisingly towards the hole but it is the reliable hand of the latest major winner on the block, Anna Nordqvist, who birdies to keep Team Europe two up.

As we come up to the turn how fortunes are reversed.

Brittany Altomare putts straight back up the slope from over 10ft away to birdie the eighth hole and suddenly their share of the leaderboard turns red as they lead for the first time.

Poor read from Sagstrom on 11 as her putt from no more than five feet doesn't even have a look at the hole as it drifts by miles right.

That was a guilt-edged chance that's just gone begging as Europe can't seem to buy a putt at the moment.

Take a bow Jennifer Kupcho! The American erases another piece of blue from the leaderboard by making this one all square with a magnificent putt on the 10th.

Ciganda and Popov still kicking themselves for missing out on the last to go back to two-up and now they find themselves level.

Team USA just finding a bit of that vital momentum that’s been lacking all day.
