Emirates Team New Zealand on Wednesday edged to within one win of taking home the America’s Cup, defeating Oracle Team USA in a close-fought race that again showcased the Kiwis’ seamless teamwork and superior strategy at the start. But New Zealand had to wait at least another day to clinch the Cup after Wednesday’s second race was postponed seconds before the starting gun due to high winds, the second straight day that a strong sea breeze and outgoing tide combined to make conditions on San Francisco Bay unsafe for the fragile 72-foot catamarans.
