Serena Williams advanced to the second round of the U.S. Open on Tuesday, defeating CoCo Vandeweghe 6-1, 6-1 in 55 minutes.
Coming off wins at Wimbledon and the London Olympics, Williams looked sharp, committing only nine unforced errors.
In search of her 15th Grand Slam title and fourth U.S. Open championship, Williams improved to 48-1 in first-round matches at Grand Slams. During her on-court interview after the match, she gave a shout-out to another Olympic gold medalist, Carmelo Anthony, who was in the stands cheering for Williams.
Vandeweghe, who fell 7-5, 6-3 to Williams in the Bank of the West Classic final earlier this summer, had trouble dealing with her toss in the blustery wind. She finished with six double faults and only held serve once in seven tries.
