Team NZ increase America's Cup lead Team New Zealand's upwind dominance came to the fore again as they scored a crushing victory in race five of the America's Cup to extend their lead over defenders Oracle Team USA. The Americans then promptly used their "postponement card" - each crew have one in the regatta - resulting in the day's second race being called off. There is a rest day on Thursday, and competition is scheduled to resume on Friday. Team NZ's 1min 5sec result in 18 to 23-knot winds took their points tally to four in the first-to-nine match, while Oracle are on minus one. There were long faces on board USA17 after the defeat, a big turnaround from the previous day's racing on Monday, which ended with the Americans on a high after scoring their first win. They stayed out in San Francisco Bay for some practice, indicating there was no mechanical problem with their boat. Race five was another come-from-behind win for Team NZ, and skipper Dean Barker admitted he would have preferred to have been in front earlier on. "It's a tough way to win races, but it's working for us," he said. We would like to be controlling our fate a little bit more around mark one, but it didn't quite work out on that one. They managed to get over us on the first reach. Barker said there was plenty for his crew to work on, "but it's encouraging that we could get back into the race like we did." Oracle had the better start and led at the first two marks, but leg three, the only one to windward, proved decisive. The two giant AC72 catamarans split on rounding the second mark and when they crossed for the second time, Team NZ had moved into a clear advantage. The New Zealanders' boathandling in the tacks looked more efficient, and Oracle's Australian skipper, James Spithill, could be heard telling his crew: "We've got to get this sorted." By the end of the beat, Team NZ had turned an 8 second deficit into a huge 1min 17sec cushion and Barker was able to take his foot off the pedal on Aotearoa over the last two legs. Spithill said afterwards that Team NZ's speed and a tactical error on his own yacht were keys in the contest. "They've definitely got wheels upwind," he said. They're tacking the boat very well. We also got caught out with a sail change. We had a little bigger jib than them. I think that really hurt us on the upwind leg. Oracle began their defence on minus two as one of the penalties for cheating during the AC45 series that preceded the America's Cup.
