Sweden scored one in the sixth, but a hit by Muirhead for two in the seventh forced the Swedes to concede.

"I thought we played fantastic out there", Muirhead said. " We played well this morning, but the win just didn't come. We knew if we kept things pretty simple, but sharpened up on a few shots, we'd have a good game and that's exactly what we did.

"We're obviously delighted to take down the current champions. Its nice to finish day one with a win. The four was the turning point, and especially to get it in the fourth end gives you a great jump, as well."

In what was a close game throughout, Team USA improved to 2-0 after defeating Denmark (1-1).

The Americans stole a point in the first end and the game was even at 3-3 after five. Singles were exchanged over the next two ends before Team USA scored two in the eighth to go in front 6-4.

"We're feeling good", said American lead Tara Peterson. "We're jiving. We're super happy. It's always nice to walk away from a two-day game with two wins.

"Figuring out the ice right away is a huge advantage. It's swingy, it's fast, it's great, so we can manipulate a lot of shots - it's fun when you can do so many team shots."
