America's Cup: Team New Zealand in total command with a 3-0 lead over Oracle

Jimmy Spithill vowed to come out swinging but it is Team New Zealand who continue to land the big blows.

Flying high after going two from two on day one in Bermuda, the Kiwis went up another level on Sunday (Monday NZ time), winning both races by comprehensive margins to take a 3-0 lead in the battle for the America's Cup.

With still four wins required to win the Auld Mug for the first time since 2000, and the epic collapse of 2013 still fresh in the memory, Team NZ will know there is still plenty of work to do.

However, the pressure is well and truly on the defenders as the teams take a five-day break before racing resumes on Saturday (Sunday NZ time).

* Spithill admits Team NZ has the faster boat

"That was certainly another good day for us," Team NZ flight controller Blair Tuke said.

"We got a couple of good starts, although that last one was pretty unconventional, but the boat's going really fast and the boys did a good job to get it around the track nice and smooth.

"It's turning out quite nicely for us."

With winds slightly heavier than Saturday, in the 8-12 knot range, Oracle were expected to be more competitive.

But they had no answer as Team NZ won race three by 49 seconds before extending their dominance to 1m 12s in race four.

Oracle skipper Spithill admitted New Zealand showed impressive acceleration off the line.

However, having pulled off one of the most remarkable comebacks in sport to beat Team NZ four years ago, this is familiar territory for Oracle. 

And Spithill, who knows as much as anyone how quickly fortunes can change, was refusing to panic.

"We've been here before so it's not over," the Oracle skipper said. "We've got five very important days now and we've got to use them wisely.

"We've got to get faster, it's pretty obvious."

Even despite a poor gybe early in race four, when he turned before getting the dagger board down, Kiwi helmsman Peter Burling continued his rapid improvement in the startbox to jump off the line and take a four-second lead at mark one.

That stretched to over 300m during the third leg as the Kiwis showed shrewd match-racing skills to cover Oracle's every move.

Burling, Glenn Ashby and Blair Tuke read the wind shifts beautifully throughout and with their boat holding a clear speed advantage, Oracle were left hoping for a mistake to let them back into the contest.

And while they had some nervous moments during their first two wins on Saturday, it was all smooth sailing to send the Americans back to the drawing board.

In race three, the teams crossed the startline virtually neck-and-neck which continued through to the first mark.

However, Oracle were made to pay for a slight mistake during their first gybe as Team NZ rounded mark two 11 seconds ahead.

Racing with their heavier air foils, Oracle showed decent speed but sloppy maneuvering allowed New Zealand to continue to build their lead over the next two legs to 48 seconds and they never looked back.
