Oracle Team USA defeated Emirates Team New Zealand for the fifth America's Cup race in a row on Monday, again denying the Kiwis the one victory they need to take the trophy.
The Kiwis crossed the start a touch ahead of the defending champion, but the Americans darted ahead and rounded the first gate with a lead of just a few seconds.
The US catamaran extended its lead slightly by the second gate and into the critical upwind leg of the race, with the Kiwis spliting toward shore while Oracle aimed for Alcatraz Island.
The Americans managed to hold a lead of more than 100 meters into a downwind leg where the Kiwis were hot on their trail.
Oracle Team USA crossed the finish 33 seconds ahead of the challengers and because light winds delayed the start of Race 16, there was no time to hold the second planned race of the day.
The next race was postponed to Tuesday.
The Kiwis, who won six of the first seven races, led 8-1 last Wednesday with nine wins needed for the Cup but have been unable to grab the clinching victory while the hosts, who were docked two points for pre-regatta violations, have mounted a thrilling comeback and need only three more wins to retain possession of the Cup.
