One fine tee shot on the par-three 16th and the Americans will likely seal at least a half in this fourth match.

Up steps Sarah Schmelzel and that is a pearl. Inside four feet and she is delighted, waving her arms and whipping up the crowd.

And in fact, the Europeans can only make par and will need Lilia Vu to miss a short birdie putt to keep this match going.

Emily Pedersen almost drained a monster but the ball stopped just a couple of rolls short, so up stepped Ally Ewing with a short putt to square the match, but she misses!

Europe go dormie one (one up with one to play) meaning they're guaranteed at least half a point here - but they'll want the full one.

They may have got it had they not conceded the short putt left for Jennifer Kupcho - who pounced on the ball quickly to pick it up as she definitely didn't fancy that one to save the match.

At the 15th hole, Carlota Ciganda is weighing up another putt to win a hole for Europe and narrow the gap further.

It's from fully 20 feet though and she's off line, opening the door for Sarah Schmelzel to halve the hole.

And the Solheim rookie for USA does that. Europe two down with three to play in this match.

A first look at the 17th hole today and USA have the advantage off the tee as Emily Pedersen tugs her drive into the left rough after Ally Ewing smoked an absolute bullet right down the middle.

Maja Stark drives in the four-foot par putt that Americans would call a 'clutch' effort, before Jennifer Kupcho trickles in a par putt from a couple of feet for a half both teams will settle for.

A very relaxed Rose Zhang and Lauren Coughlin have just been chatting to the television cameras after winning their foursomes match 3&2 against Celine Boutier and Albane Valenzuela.

“We had so much fun together," said Zhang. "Every shot we were laughing. We had some clutch putts coming in so that really helped the momentum

“Look at the fans," Coughlin agreed. "Over at 14, it was quite a scene and it was pretty special. It’s been amazing."

Big miss by the Americans on the par-three 16th to miss the green to the right down a big hill, but the recovery is excellent.

Emily Pedersen is then feeling the pressure and blazes her birdie putt well past the hole and now Maja Stark is facing a nervy one coming back probably just for the half.

Strains of "ole, ole" reverberate around the 14th green as Carlota Ciganda sinks a crucial putt to win the hole.

She stands fist aloft and looks steely. It's enough to trim the gap on the US to two with four holes left to play as Europe try to wrestle back some momentum in this session.

The Europeans fail to get down in two from the edge of the green which leaves a comfortable two-putt for the home side to reduce the gap down to just one hole.

Four down after three and second best for most of the day, Ally Ewing and Jennifer Kupcho can sense an epic comeback on the cards.

This match is now monumental for Europe with how this session is going so far, and Jennifer Kupcho is feeling it as she hammers an iron out of the right rough on 15 and finds the green.

Maja Stark then comes up short of the putting surface and all of a sudden there's huge pressure on the Europeans, who had been in total command for most of this one, until now.

We found our highlighters - that's a clearer leaderboard!

Albane Valenzuela misses a chance to birdie to win the 16th hole and keep match two alive then watches Rose Zhang duly makes par.

Roars from the partisan home fans, who are now packed in three or four deep at the edge of the green as the USA go 2-0 up.

Ally Ewing rolls in a putt to win the 14th and Europe's lead in this match is cut to just two with four to play.

That's probably the biggest cheer of the day as fans continue to keep streaming in following the transport problems getting here.

And when the American fans come in and see the scoreboards they'll be delighted.

Critical putt for Linn Grant at the 13th to halve the hole for Europe and she's lagged it.

Lilia Vu and Sarah Schmelzel are now three up and closing in on another point for the United States.

Nelly Korda and Allisen Corpuz won both foursomes matches in Spain and are now the first American duo to win three straight matches in the alternate shot format in Solheim Cup history.

"We just vibe really well," said Korda on Sky Sports. "And when one of us didn't hit it well we really relied on each other and we kept calm out there.

"I've got such a great partner, she comes up clutch every single time and I couldn't ask for a better one."

Celine Boutier looks a little despondent with her body language after she sinks a tricky putt for par at the 15th. Rose Zhang has an altogether more comfortable position on the green and taps in to halve the hole.

The USA remain three up with three to play in match two.

Allisen Corpuz and Nelly Korda have won three out of three foursome matches over the past two Solheim Cups.

Wonder who US captain Stacy Lewis will be rolling out tomorrow morning...

There it is! Allisen Corpuz rolls in the birdie on 16 and she closes out the match with Nelly Korda to beat Charley Hull and Esther Henseleit 3&2 in the headline match of the session.

That ding-dong match went one way and the other, but the USA won three in a row just when it mattered most to put the first point on the board.

Nelly Korda is looking to close this match out at the 16th as she hits her tee shot on the par three nice and tight.

Charley Hull answers with a decent effort, although a few feet outside the Americans - who will win the match if they take this hole.
