“It’s difficult to analyze now,” the second-seeded Nadal said, when asked if this is the best he has ever played on hard-courts. “I am playing well. Happy the way I was playing. I don’t know if it was the best or not, but it was very good because I was able to win.”
Nadal is looking for his second US Open title. He won his first in 2010 beating Novak Djokovic.
Other notable winners on day one at the Open include, (4) David Ferrer, (8) Richard Gasquet , (1) Serena Williams, (3) Agnieszka Radwanska, (5) Li Na, (15) Sloane Stephens and Venus Williams.
