Newly-crowned Ricoh Women's British Open champion Stacy Lewis says home advantage is key in the Solheim Cup.
The Americans are unbeaten in the six Solheim Cups played in the United States and Lewis, who captured her second major when winning at St Andrews a fortnight ago, believes she knows why.
"There is so much red, white and blue out there and it's going to be a huge advantage," said the world No 2, who also helped the US beat Great Britain and Ireland in the Curtis Cup at St Andrews in 2008.
"Already, I can see a lot of differences in playing at home. I've actually played this course (Colorado Golf Club) a lot on three or four visits. Length will be important but it's going to come down to the greens. They are very tricky."
Lewis said the 2011 Solheim changed her as a golfer and a person - and it was all for the positive.
"I wouldn't be the player I am today if it hadn't been for Ireland two years ago," said the top American.
However, Lewis also had some scary news for the rookies.
"There's a certain feeling you get when you walk up the 18th with a lead in a major," she said. "Well, at the Solheim, you get the same feeling on every hole."
The USA has four rookies - Lizette Salas, Jessica Korda, Gerina Piller and 18-year-old Lexi Thompson - and Salas was overwhelmed by the presents given to each player.
"When I got to my hotel room it was better than Christmas," said the 24-year-old. "This has always been a goal of mine. I remember watching Cristie (Kerr) and Paula (Creamer) playing in the Cup when I was about 13 or 14 and thinking that I wanted to be part of the Solheim experience."
Piller, who reckoned the best gift of the week was a pair of cowboy boots in red, white and blue, was a rookie on the LPGA Tour in 2011 and was invited to be a guest at Killeen Castle by Angela Stanford. This year they are team-mates.
"Gerina is one of the young bombers in our team and she's going to be great," said Stanford, a veteran of four matches. "We have a great young team and I'm looking forward to a real birdie fest."
