Great Britain and Ireland enjoyed a superb start as they looked to regain the Walker Cup against the United States, claiming a 3-1 lead after the first session at Royal Lytham.
The English pair of Ashley Chesters and Jimmy Mullen led from the front in the opening foursomes, defeating Maverick McNealy and Hunter Stewart 3&2.
Northern Ireland's Cormac Sharvin and Scotland's Jack McDonald then eased to a 5&4 victory over Jordan Niebrugge and Robby Shelton, with the Irish pair of Jack Hume and Gavin Moynihan beating Lee and Mike McCoy 3&2.
Only Greystones man Paul Dunne - who shared the lead after 54 holes in the Open at St Andrews - and West Waterford's Gary Hurley slipped to defeat despite recovering from an early two-hole deficit to Beau Hossler and Denny McCarthy, the Irish pair crucially making three bogeys in succession from the 13th.
The omens did not look good when Mullen's weak tee-shot on the par-three first came up 20 yards short of the green, but Chesters hit a superb pitch and the subsequent par was good enough to win the hole after their opponents failed to get up and down from a greenside bunker.
"I was more nervous hitting that shot than playing in the Open (at Muirfield in 2013)," Mullen admitted. "It was an awful shot but at least I made up for it with the par putt."
The match was all square after eight holes before Stewart suffered an airshot on the ninth when his club caught the bank of a bunker on his downswing, the American pair then conceding the 10th after twice tangling with the same gorse bush.
Shelton and Niebrugge, who finished sixth in the Open to win the silver medal as leading amateur, were an approximate nine over par in their comprehensive defeat to University of Stirling room-mates Sharvin and McDonald.
"We just kept going and building momentum and just did not really give them much," said McDonald, who was being watched by his grandfather Gordon Cosh, who played in the 1965 contest. "It was great to be out there with Cormac and having great fun."
Hume and Moynihan, who is the sole survivor from the team beaten 17-9 two years ago, were never behind in match four, but Dunne and Hurley's nine-match unbeaten run together came to an end in disappointing fashion after they had conceded the 11th to get back to all square.
