Ben Ainslie's JP Morgan BAR team near to victory after dominating America's Cup regatta in San Francisco With one fleet race to go in the seven-race series, Ainslie had established a hefty 11-point lead in only his second ACWS event, after posting a string of impressive results including three outright victories in a field that featured some of the most experienced and successful skippers in the America's Cup. It was not, however, a clean sweep of rosettes since he was beaten in the match racing competition by Oracle's Jimmy Spithill with whom Ainslie will be fighting for a place as skipper of the Oracle AC72 when the America's Cup starts properly in San Francisco next year. Spithill, who helmed the Oracle boat when the Americans took the Cup in 2010, went on to win the match racing competition, beating Dean Barker's Emirates Team New Zealand in the final despite capsizing spectacularly in a fleet race one hour earlier. But he was beaten by Ainslie in the final fleet race of the day on Saturday in a contest that is likely to get increasingly fierce and fruity as the months go by. Another epic day on the water! Ainslie tweeted later. JP Morgan BAR finished with fourth and first in the days two fleet races. In the fleet racing, Ainslie has benefited from having some experienced hands to help fast track his learning curve including New Zealanaders Simon Daubney and Matt Mitchell, Kyle Langford from Australia and Dutch bowman Simeon Tienpont, who together form a formidable team. Ainslie was set to complete his challenge for a remarkable victory last night with the next event set to take place in Venice next April.
