USA only need one-and-a-half points but there ain't any red on the board at the moment.
To be clear, the three all square matches would be sufficient to win the Solheim Cup.

USA only need one-and-a-half points but there ain't any red on the board at the moment.
To be clear, the three all square matches would be sufficient to win the Solheim Cup.
Coughlin v Stark A/S (14)
Maja Stark messes up a drive on the fairway at the 14th and then ends up in the water with her next shot.
She scrambles back for a chance to putt for par but misses and concedes
Lauren Coughlin has battled back from three holes down to go into the final four on level terms.
Thompson v Boutier A/S (15)
Celine Boutier was three down after 11 holes, now she rolls in a birdie on 15 to level her match with Lexi Thompson!
Pressure is on.
1UP Thompson v Boutier (14)
Lexi Thompson hits a nice approach to the 15th - about pin high but about 20 feet and trying to work back closer.
But Celine Boutier can do better as she lands hers about seven feet from the target and she's got the advantage as they reach for their putters.
We're going to be throwing lots of these at you over the next half hour.
This is getting exciting.
Schmelzel v Sagstrom A/S (12)
Amazing shot from Madelene Sagstrom on 13 - I think it was still 13 but she was in a huge ditch in some juicy rough, but she's escaped brilliantly to finish just four feet or so from the hole.
Vu v Valenzuela 1UP (12)
We've been watching this competition for three days and European putts haven't sunk.
They are doing now. Massive again from Albane Valenzuela who has inched ahead of Lilia Vu in the ninth match.
European momentum.
The changing colours on a Sunday.
Team USA have been singing and dancing their way through this Solheim Cup all week, but now things are getting serious that's all stopped.
The hosts are on the cusp but this could still go either way.
Europe are ahead in three, USA are ahead in one and three matches are all square. If those three turn blue Europe would get to that magical 14-point mark.
And another tie!
Kupcho v Grant A/S (11)
Linn Grant! Another majestic putt from the Swede who was three down after three holes today.
Now, she's level!
Suddenly, the US are only up in one match!
Coughlin v Stark 1UP (13)
Maja Stark methodically putts for par to halve the hole at the 13th and put a stop to Lauren Coughlin's birdie run.
Coughlin has been 3-0-0 over the past few days. She is not giving this up without a scrap.
6&4 Zhang v Ciganda
Rose Zhang spoke to Sky after seeing off Carlota Ciganda 6&4:
"I was really excited. Carlota is such an incredible player and I saw her clinch that cup last year. I was really just looking forward come out here and see [if] I can measure up.
"It turns out the day was great and I’m glad to be gaining a point for Team USA. My team-mates are incredible."
On how the USA have dominated in the back nine: "Overall, we're aggressive players and we know where to place the ball and we allow the slopes to do their thing and just allow the golf balls to ride with it.
"We’ve been pretty creative with how we’ve been playing the holes and getting the job done."

Rose Zhang led all players this week by winning 28 holes while losing only eight.
That +20 win/loss difference is easily the most dominant of the last 10 years.
The next best performance over that time is by Jessica Korda, who won 29 holes and lost 15 (+14) in 2019.
Schmelzel v Sagstrom A/S (12)
Sarah Schmelzel AGAIN! I'd love the stats on the footage of putts and chips she's made today after she cans another long ranger to level the match with Madelene Sagstrom.
Europe led by a couple in this not too long ago so that's a dagger for the USA.
1UP Thompson v Boutier (13)
How about this then, both Celine Boutier and Lexi Thompson are on the green on the 14th so it will be a putting competition in what's turning out to be a belter of a match.
A huge, rowdy crowd belts out Lexi's name as she reaches the putting surface holding a slender one-hole lead.
Kupcho v Grant 1UP (10)
How about this from Linn Grant, who has not got going yet at the Solheim Cup so far.
Now is a nice time to find her form and she's cut Jennifer Kupcho down to just one up in the final match.
That could be key!
Coughlin v Stark 1UP (12)
Lauren Coughlin is not going to lie down on this back nine. Back-to-back birdies sees her take another hole off Maja Stark at the 12th, with the Swede now just one ahead.
It's boiling up on the Robert Trent Jones Golf Course.
An Lee v Henseleit 1UP (14)
Hold on to your hats, Andrea Lee is fighting back against Esther Henseleit after landing a dime on the green.
She's trimmed the lead to just one with four to play.
Some seriously tight matches now.
Look at all those one-hole gaps!
Can Europe dig this out?
Thumbs up if they can stop the US from getting what they need...
1UP Thompson v Boutier (13)
Steve Sutcliffe
BBC Sport in Virginia
Things are just getting a little twitchy on the 13th, where I’ve bumped into George and Karen as Celine Boutier claws back another hole on Lexi Thompson.
Even though this is her final Solheim Cup, the American as ever, does not show a trace of disappointment and stops twice to sign items for children on the walk to the 14th tee.
