NEW YORK — Good as she is, even Serena Williams can find it tough to deal with swirling wind, so much so that she double-faulted three times in her first service game Thursday at the U.S. Open.And, yes, even a 17-time major champion such as Williams can lose in the early going at the sport’s biggest tournaments, as she has repeatedly in 2014.Quickly putting behind a poor-serving start, and showing absolutely no other signs of the type of up-and-down play that has plagued her at Grand Slams this season, Williams dismissed 81st-ranked American Vania King 6-1, 6-0 in 56 minutes to reach the third round.“She never let me in,” said King, who is 25. “She’s played at such a high level for so long, and I used to watch when I was a kid, growing up. So it’s kind of surreal to see the person that you’ve been watching on TV in front of you and playing.
