Even after losing two races on Sunday, Spithill was not in any mood to give up, conceding that the US crew had been outsailed by Burling and his five Kiwi team mates, but vowing to come out fighting again on Monday and take one race at a time.
"We've taken advantage of every minute we could this week to make improvements", Spithill said.
"We know we can do this", Spithill said. "There's more on the table". On Monday, we'll see if Spithill has the makings of another miracle up his sleeve.
The sight of the boats skimming over the crystal clear waters of the natural sailing "arena" has drawn new audiences for sailing both in Bermuda and on television.
Emirates Team New Zealand claimed global sport's oldest trophy with a stunning 7-1 victory in Bermuda's Great Sound, with 26-year-old Peter Burling becoming the youngest helmsman to secure sailing's biggest prize.
"Full credit to the guys, holding it tight not giving them any chances to get back in the race". You saw it in the Artemis race when the Umpires admitted they made a mistake.
Burling said later he was merely pleased that he nailed the maneuver that allowed the Kiwis to sail away to its second win Sunday on the Great Sound and reach match point in sailing's marquee regatta at 6-1.
Racing continues on Sunday afternoon.
Burling, 26, bested Spithill in the pre-start of both races, and the United States of America couldn't recover either time.
"I still think we can win races with this boat".

After splitting Saturday's two races, Spithill piled on the Kiwis.
Regardless of who wins, Ainslie is calling for a quick decision on the format to keep the momentum from Bermuda and is a strong advocate of the World Series lead-up event, which has boosted support for fans and broadcasters.
Spithill broke away halfway up the beat but it came at the cost of an extra tack. Spithill forced a slow rounding on the New Zealand boat and made a pass early on the run.
