Anna Nordqvist helped maintain Europe's Solheim Cup lead after closing out Saturday's top foursomes match with a stunning hole-in-one.
After a short birdie putt at 16 had put her and Caroline Hedwall level with Morgan Pressel and Jessica Korda, Nordqvist delivered the killer blow by holing her seven-iron tee-shot at the par three 17th.
That, the first ace in Solheim Cup history, kept Europe ahead by the slenderest of margins at 6½-5½ after an American fightback on the second morning.
Nordqvist's ace put Europe 6-3 up overall after they had led 5-3 overnight, but with Stacy Lewis and Paula Creamer taking a nailbiter for the home side, and Michelle Wie holding her nerve to take another match, that soon became 6-5.
It was left then to Catriona Matthew to land a nervy final-hole putt to share a point with Brittany Lincicome and Lizette Salas to keep Europe just ahead.
Nordqvist's story was the headline, though, especially after she and Hedwall had been a hole down with five to play before their late brilliance.
It had appeared as though their performance had echoed down to Azahara Munoz and Karine Icher too, with the duo pegging back Lewis and Creamer having trailed by four as the started the 11th.
They levelled going into the last but carded a horror six on the par-four and watched their rivals take the match with a birdie three.
That made it 6-4 and when Wie held it together to sink a winning putt when paired with Brittany Lang against Suzan Pettersen and Beatriz Recari - the latter had spurned a putt to take the match to the final hole.
It had looked at that stage as though America would level at 6-6, but Matthew kept it together to keep a share of the final game of the morning.
