To be pushed all the way by Olivia Rogowska, a player ranked 166 places below her and who needed a wildcard for entry into the draw, does not suggest a dominance over the women's game.
The only bonus for the Russian top seed is the lack of any seeded opposition until the fourth round. That would have guaranteed an early end to her tournament.
Instead, she will have to overcome some top-100 players, who will now believe she is beatable. As do most tennis fans.
At this early stage, both Serena Williams and Elena Dementieva, the second and fourth seeds, look to be in very good form -- ominous for their nearest rivals.
Helping the American's cause will be the early departure of Sybille Bammer.
Wily
The wily Austrian, who has never lost to the world number two, was a potential third round opponent.
It's always very difficult to judge the performance of Venus Williams.
The third seed, winner at Flushing Meadows in 2000 and 2001, struggled against an in-form Vera Dushevina, winning in three tight sets.
But Williams should bounce straight back against the colourful Bethanie Mattek-Sands, and show just how serious she is about winning this title again.
Another impressive performance was put in by Kim Clijsters, who is returning for the first time since her 2005 victory -- her only Grand Slam title to date.
The Belgian has been beaten twice since her comeback, but she had only lost to top-five players. The first she is projected to meet at this tournament? Venus Williams.
The top seeded men were far more impressive in easing through, with Roger Federer, Andy Murray and Novak Djokovic having straight-set victories.
Federer, aiming for a sixth-straight title, has re-found his best form and will be a sure bet to make at least the semi-finals.
It will take an inspired performance to push the Swiss star to four sets, let alone beat the world number one.
Dominant
Murray, in his first Grand Slam as the second seed, had the toughest opponent but was in dominant style and looks sharp and impressive.
His route through has opened up, following defeats for Ivo Karlovic and Stanislas Wawrinka, whom Murray struggled past in five sets at Wimbledon, in the first round.
Serbian Djokovic showed glimpses of why he is a former Grand Slam champion, dispatching his Croatian opponent Ivan Ljubcic with aplomb.
This was possibly the most surprising result, with the former top ten player not challenging the fourth seed.
Other contenders yet to play include Rafael Nadal and Juan Martin del Potro, with both players out to prove their title credentials.
With the top women struggling against much lower-ranked opposition, it's a relief to see the men's seeds living up to expectations.
There could be some big shocks in the pipeline in the coming rounds, and it's not difficult to guess where they might be.
