Facing an 8-3 deficit entering the day, Team USA needed to win six straight races to rally for an improbable victory, and got two of them Sunday on San Francisco Bay.
Nine points are needed to take the regatta.
In Race 14, the Americans led the entire way and notched a 23-second victory, and repeated the feat in Race 15, winning by 37 seconds after holding off a Kiwi charge on the second downwind leg.
Races 16 and (if necessary) 17 have been set for Monday.
