Little wonder. The Scot's seventh appearance topped the lot as she helped Europe win for the first time in the USA at Colorado Golf Club
Fifteen years after she first played in the competition, Matthew had no hesitation in giving an explanation to the historic win and the record 18-10 margin. "It was the rookies," she said. "They played really well. The 4-0 whitewash on Saturday afternoon also really set us up for the singles. If we had lost on Sunday it would have been a disaster."
At the start of the week, everyone had pinpointed the key to success - form on the greens. And it was proved correct. The USA had big hitters, but they could not get the ball in the hole under pressure. "The Europeans played well and made more putts," said Meg Mallon, the USA captain. "They seemed to hole the shots when it mattered, especially at the 16th, 17th and 18th. "We thought the 18th was the hardest hole on the course but I don't know how many times Europe managed to make birdie."
One of the birdies came on the final day from the outstanding Caroline Hedwall. All square on the final tee with Michelle Wie, she hit a nine-iron second shot 150 yards to four feet and holed the putt for a one hole win and a point that secured the 14 points needed for Europe, as the holders, to retain the Cup. Moments later and it was Matthew who made sure that Europe won outright with a half point against Gerina Piller.
Hedwall was the only player on either side to play in all five matches and the sturdy 24-year-old Swede won every match - a Solheim first. "It's unbelievable," she said. "I was a little tired but I was so pumped up. This is why you practise so hard, for moments like this."
For Matthew, it was a third win. She claimed the winning point with a win over Rosie Jones at Barseback in Sweden in 2003 and she was also a key member of the win at Killeen Castle in Ireland two years ago. But even the most experienced player admitted to nerves. "I was shaking," she said of her walk down the 18th. "They told me, so I knew that if I got a half we would win it outright."
Behind from the second - and two down with five to play - Matthew won the 14th and the short 17th to draw level and it was a knee-knocker of a five-foot par putt at the last that sparked more celebrations. Matthew, currently at an all-time high of No.8 in the world, reached an individual high when she captured the Ricoh Women's British Open title at Royal Lytham and St Annes in 2009, but this was just as good. "Any time you can celebrate with 11 team-mates and all the other helpers, caddies and everything, it makes it more exciting and more fun," said North Berwick's finest, who was able to share the moment with husband and caddie, Graeme and mum Joan.
This week, Matthew is competing in the Canadian Open in Edmonton, then it will be back home to celebrate and take part in the Aberdeen Asset Management Ladies' Scottish Open at Archerfield, a title she won two years ago.
Matthew, 44 this Sunday, was the oldest member of the side and the youngest, England's 17-year-old Charley Hull, represented an exciting future. The youngest ever player in a Solheim Cup, she was a wild card pick by captain Liselotte Neumann and she repaid the faith with two wins from three matches. In the singles, she thumped Paula Creamer 5&4. At the end of that match, she amused everybody by asking Creamer to sign a ball. "I've got a good friend, James, back home and he's a big fan so I thought why not?" she explained.
All week, Hull displayed refreshing naivety but, in the heat of battle, she was as mature as they come. "That's the way I always play," she insisted. "I just go up and whack it and if I hit a bad shot I'm not going to die." And she summed up the week in one word: "Wicked."
Before the match in Ireland two years ago, the USA led 8-3 and it was becoming so one-sided that the idea of USA v Asia contest was raised. Now, though, the score is 8-5 and Europe will be heading for three in a row in Germany, when the 2015 version takes place at St Leon-Rot. For Neumann, captaining Europe to the win was another highlight in her outstanding career. "I'm so proud, happy and excited," she said. The first Swede to win a major at the 1988 US Women's Open, Neumann has now made history again.
