The US team won the America's Cup in sailing today, and this is pretty much all you need to know about how huge of a comeback it was: It's a best-of-17 series, and Oracle Team USA trailed 8-1 just last week. Do the math, and you'll see why AP calls the victory by skipper Jimmy Spithill's crew over the New Zealand boat "one of the greatest comebacks in sports history." Spithill steered Oracle's space-age, 72-foot catamaran to eight straight wins on San Francisco Bay to keep the oldest trophy in international sports in the US.
