Reigning U.S. Open champion Serena Williams insists she doesn't feel any additional pressure as she attempts to complete a calendar Grand Slam.
The world's top-ranked player heads to Flushing Meadows next week having already claimed the Australian Open, French Open and Wimbledon in 2015.

"I don't feel that fresh pressure," said Williams, who will face Vitalia Diatchenko in the first round in New York. "If I make it far then maybe I will but, as of now, I really don't feel any. I'm just here to perform and to do the best I can."
Only three women have swept all four majors in a single season: Maureen Connolly Brinker, Margaret Court and Steffi Graf. Graf was the last female to achieve the feat, in 1988.
Williams — 48-2 on the WTA Tour this season — is seven wins away from adding her name to that illustrious list, but the 21-time Grand Slam winner is treating her 2015 U.S. Open campaign like any other.
"I always feel there's another record, then there's always another person to catch up with or to pass. I never really thought I would be in this position where I would even be talking about records, passing Steffi Graf or even mentioning Margaret Court.
"Wimbledon gave me unbelievable practice for this. At Wimbledon I was going for the second Serena Slam (holding all four grand slam titles at the same time). That is rare. So that really gave me the best practice and preparation in terms of going for the Grand Slam."
