The match that could decide the series.
Tommy Aaron (US) v Roberto de Vicenzo (Argentina) at Carnoustie

The World lead 6-5 with two matches to play. A win for de Vicenzo, reigning individual World Cup champion and former British Open champion, would clinch the series. Victory for Aaron, member of the last Ryder Cup team, or a halved match will mean that the result depends on next week's final match.
De Vicenzo might have won the American Masters title in 1968 had it not been for Aaron. The American made an error on Roberto's card, and the Argentinian failed to check it: thus he was disqualified.
