Oracle Team USA has performed one of the greatest comebacks in sport's history to win the America's Cup.
Down eight races to one with Team New Zealand poised on match point, Oracle won the last eight race races of the regatta to retain the Auld Mug.
In Thursday morning's winner takes all final race, both boats crossed the start line together, but Team New Zealand lead around the first mark by seven seconds.
Aotearoa maintained a slight lead over the first downwind leg, but only rounded the second mark three seconds ahead.
Upwind the lead changed as Oracle again showed superior speed sailing into the wind.
By the third gate Oracle had built an insurmountable 26-second lead and Team New Zealand could only watch as the quicker boat streaked away.
Team USA crossed the finish line on San Francisco Bay 44 seconds clear of the challengers from New Zealand.
