LLANWERN'S Jack Davidson had a chastening experience on his Walker Cup debut, after Great Britain and Ireland were crushed 19-7 by the United States at Los Angeles Country Club.

Davidson, who went into the two-day amateur team golf event on the back of a stellar season, failed to pick up any points in either the foursomes or singles.

On day one, Davidson and fellow Welshman David Boote suffered a 5&4 defeat to Maverick McNealy and Doug Ghim in the foursomes, while the Gwent ace didn't play in the afternoon singles.

And it didn't get any better on day two, with Davidson and Boote on the wrong end of a 6&5 thrashing at the hands of Will Zalatoris and Cameron Champ.

Davidson then lost 3&2 to Zalatoris in the afternoon singles.

Great Britain and Ireland had trailed their hosts by four points heading into the second day.

But the Americans eased themselves into an 11-5 lead and within two-and-a-half points of victory after winning the morning foursomes 3-1.

And they duly wrapped up the win in the singles, surrendering just one-and-a-half points in the 10 matches.

McNealy, Ghim and Collin Monikawa all won their four matches over the two days, an unprecedented feat in a single event.

McNealy said it had been an unforgettable week.

"I think it starts with the US team getting that big trophy and that was our goal at the beginning of the week, and I'm so excited to be part of the 2017 winning Walker Cup team," he told the USGA.

"That's what's most important to me. I'm so glad we could win this for our team, win this for captain (Spider) Miller, and win this for the country.

"It's been unbelievable. I'll never forget this week. It's the end of my amateur career but it means so much more than that to me, it's been incredible."

Captain Spider Miller, 67, who also skippered the US when they were beaten last time out at Royal Lytham and St Annes, could not hide his delight with his team's performance.

He added: "They have conducted themselves great this week.

"They have done everything I've asked and I'm very proud of them all."

Great Britain and Ireland captain Andy Ingram paid tribute to the "amazing" winning team.

"Got to take my hat off to them, they have been superb all week," he said.

"This is such a wonderful place. I love the climate, I love the people, I love the golf course. We have had some great fun."
