Team New Zealand have moved one step closer to America's Cup glory and are now just three wins away from lifting the Auld Mug from Oracle Team USA off Bermuda.
The Kiwis won their fifth straight race to take a 4-0 lead in the first-to-seven format, suggesting that the five-day break in competition has not closed the gap out on the water.
Oracle skipper Jimmy Spithill made a big tactical mistake at the start, gaining the best position on the line, but encroaching early for a two-boat length penalty.
Emirates Team NZ led by a few seconds around the first two marks, but helmsman Peter Burling had to withstand Spithill's aggression and a faster Oracle ACC boat upwind in 11-knot breezes.
The American team actually took the lead briefly up the third beat, but copped another two-length penalty for crossing too close to the NZ boat. That proved the decisive moment of the race and soon afterwards, Oracle fell off their foils in a gybe, to concede several hundred metres.
The final margin was more than two minutes.
