Given that Team GB haven't won the overall fourball matches at the Simpson Cup since 2012, the Americans will have fancied their chances going into day one at Royal Birkdale Golf Club on Tuesday. But even in their wildest dreams, they couldn't have imagined taking a 6-0 lead into the 12 singles matches on Wednesday.
The defending champions simply blew their British counterparts away, on a perfect day for golf in which the host nation may have preferred the wind to blow. The benign conditions suited the visitors' explosive ball striking, and they seemed to have the measure of their opponents from tee to green.
The crusade was led upfront by the pairing of Chad Pfeifer and On Course Foundation ambassador Chris Bowers - the former being an amputee and professional golfer.
They reached the turn 6 up on the English combination of Rob Hansen and skipper Paul Skivington, before closing the deal 8&7 a couple of holes later. Pfeifer in particular was exceptional, playing the requisite 11 holes in level par with his own ball, although Bowers provided handy support in a crushing performance.
It sent a message to the matches behind, and a stunned home side seemed to have little to offer in reply. Chris McCoy and Billy Paul wrapped up their match 7&5 against Andy Stevens and Nathan Blewer; Mike Lacy and Mike Stafford overcame Jason Evans and Pete Wood 4&3, while Andrew Bachelder and Steve Ogletree raced away to win 3&2 against Dave Hughes and Alex Hiles, despite having been 1 down after eight holes.
It needed the Brits to summon their inner Churchillian stoicism, and the pairing to do so were Ian Bishop and Dave Ward. Staring down the barrel at 4 down with six to play, the duo combined to force a final-hole climax to the match. However, a birdie for Cody Boyer at 18 after an incredible approach proved too much, and he and partner Todd Tongue celebrated a tense 2-up victory.
It was thus left to the final match on the course to provide some inspiration for Team GB, and it appeared to be going their way, as the formidable duo of Mike Browne (a professional golfer) and Tony Lownds (unbeaten in the Simpson Cup in three previous appearances) reached the 14th hole in good shape at 2 up.
However, US captain Shawn Whitmore and Jake Nelson (a scratch handicap) cranked things up a notch to win the next two holes, before the teams halved in par on the 16th. The excitement levels reached fever pitch as Whitmore then halved the 17th hole in birdie with Browne - the latter completing a miracle two putt from left of the green.
Up they went to 18, and it was Lownds who appeared to put the Brits on course for a much-needed point, hitting a bunker shot to just 8 feet, and a chance for a crucial birdie. But instead, it was Nelson who holed a bomb of a 35-foot putt for a four of his own, and when Lownds narrowly missed to the left, the 6-0 rout was complete.
"That was a thrashing, no doubt about it," a disappointed Skivington commented afterwards. "Chris and Chad were exceptional against us, but I watched the rest of the guys come in, and the Americans played some brilliant golf. All credit to them for a fine performance, but we know what we can do in singles, and I can promise you that this one isn't over."
Certainly, Skivington's charges can look back with fondness at their record in singles, with an aggregate score of 35-25 in their favour over the previous five Simpson Cups. But they will have to extract every ounce of the famous Medinah spirit to even run the Americans close, and, for Whitmore, the biggest challenge of all may well be to guard against complacency.
"I couldn't be more proud of my guys," he beamed after winning his crunch match. "We had a mission out there today, and every one of them executed. This was as good as we could have hoped for, and for us, it was extra special, as we played for Dave (Bagby, a former teammate who passed away last year). The Simpson Cup at Royal St George's was the last time I played with him, and today it felt like he was up there watching over us."
He added: "But the mission tomorrow doesn't change. There's still a job to do, and we're going to be giving it everything."
Wednesday's singles matches get under way in tantalising fashion, with the much-hoped-for showdown between Browne and Pfeifer scheduled to kick things off at 9am (BST). Other notable matchups include Hughes (2) versus Nelson (0), and double-amputee Bishop (9) against the big-hitting Boyer (3). And, should the Brits produce a comeback for the ages, it may come down to the two captains Skivington and Whitmore, who'll be squaring off in the final two-ball.
What a day of golf it promises to be, and with the breeze forecast to pick up on Wednesday afternoon, it may just feel a bit more like home turf for the host nation. They have it all to do though if they are going to accrue the 9-and-a-half points they need to regain the Cup. As for the Americans, it's merely a case of as you were once the first shot is fired.
