Updates from...
GREHAN BEATS STOUT!
After Preston Stout's long birdie putt comes up short, Stuart Grehan has two putts to win it at the 17th. His first is close and the second does it. Another point for GB&I!
NOW OR NEVER
Both Preston Stout and Stuart Grehan find the fairway with their tee shots at 17.
Stout, who is 2-down, is first with his approach, and it just fails to make it to the green...
Grehan does marginally better, his ball settling a few feet onto the putting surface.
STOUT HANGING ON
We're approaching the business end of Stuart Grehan's match against Preston Stout.
At the 16th, Grehan completes an up-and-down, leaving Stout needing a par to halve the hole.
He does it and stays alive in the match.
GB&I STILL IN THE HUNT
There are shades of Team USA's remarkable Sunday singles Ryder Cup comeback against the Europeans at Bethpage Black here.
On that occasion, Luke Donald's men held on, but will that be the case for the visitors here?
At the moment, needing seven points to win, the hosts have one full point banked, are up in five matchups and all-square in two...
POULTER IN THE ZONE
A big moment at the 12th, as Niall Sheils Donegan wins the hole to drag things back to all-square against Kihei Akina.
STOUT HITS BACK
Preston Stout rolls in a long putt against Stuart Grehan to cut his lead to 2-up. You can't write him off just yet!
MORE GB&I JOY
Tyler Weaver is flying against Jay Leng Jr. He goes 4-up at the 12th after converting his short birdie putt.
RUSSELL TURNS SCREW
Some respite for the US as Miles Russell goes 2-up against Connor Graham at the 10th. They'll take anything they can get at the moment.
POULTER ON TOP
Luke Poulter also has the better of 2025 Amateur Champion Ethan Fang. He goes 3-up at the 13th!
GREHAN IN CONTROL AGAINST STOUT
World No.1 Preston Stout is out of sorts, and with a par putt at the 14th, he misses right. He's not happy, as his chuntering afterwards confirms. Stuart Grehan makes his putt and goes 3-up!
BOLTON LOSES LEAD
Ben Bolton loses his 1-up lead against Ryder Cowan. The American wins the seventh hole to give the US a foothold.
CLOSE FOR WEAVER
It's safe to say you'd typically back the US in singles matches, but that's not how things are working out at an overcast and grey Lahinch Golf Club.
Tyler Weaver has a long putt at 11 to win the hole and go 4-up against Jay Leng Jr, but it trickles right.
BLUE IS THE COLOR
Remarkably, if things stay just as they are, that would give GB&I the win. That's because Josh Hill has just gone 1-up against Tyler Watts, giving the hosts the lead in six matches and with blue dominating the leaderboard.
ONE DOWN, SIX TO GO
Well, that's one point in the bag for the hosts, but there is still plenty to do.
To be precise, GB&I still needs six points from the remaining nine matches.
Tyler Weaver looks the most likely at the moment. He's 3-up against Jay Leng Jr.
FIRST BLOOD TO GB&I
A comfortable win for Jack Whaley against William Jennings sees GB&I claim a much-needed point. Whaley claims a whopping 8&7 win over his opponent to give GB&I a total of 7.5 points.
Remember, they need 13.5 points to reclaim the Walker Cup. The US, on 9.5 points, just needs to get to 13.
AS IT STANDS...
As things stand, Team GB&I are making an excellent go of it. A lot can change, but currently, six of the 10 matches are going in favor of the hosts, with one A/S. Just two US players lead at the moment.
That still wouldn't be enough for a stunning GB&I win, but they're in with a chance...
WELCOME!
Welcome to our coverage of what remains of the 51st Walker Cup.
There are 10 singles matches left to complete, with Team GB&I needing seven points to reclaim the Walker Cup and Team US just 3.5.
