Wozniacki made the final at Flushing Meadows last year, losing to the more experienced Belgian Kim Clijsters, but believes she is in much better shape this time.
“The last two weeks, or actually four weeks, have been great for me. I've been winning a lot of matches so that's definitely something that brings up the confidence,” the Dane told a news conference on Sunday.
“I'm feeling really good. It's tough to compare myself to one year ago...but I definitely think that I've improved in many aspects.”
The 20-year-old has climbed to number two in the world rankings and has been promoted to top seed for the US Open after the withdrawal of Serena Williams with a foot injury.
Wozniacki, who starts against American Chelsey Gullickson, is in great form after a punishing month of tournaments highlighted by winning the Danish Open and back-to-back titles in Montreal and New Haven.
“After Wimbledon I had five weeks off where I didn't play anything and just practised, so that was a great feeling for me to get back on the match court and back in the match intensity,” she said. By winning in Montreal on Monday then New Haven on Saturday, Wozniacki ensured she finished the US hardcourt series as the leading pointscorer and if she wins the US Open she will pocket a $1 million cash bonus.
A Grand Slam title is what appeals to her most, though. “That would be a dream, to win a Grand Slam, that's definitely a goal but it's still seven matches away, and it's tough because everyone wants to win,” she said.
