New York: Top-ranked defending champion Serena Williams rolled into the third round of the US Open on Thursday while Italian fourth seed Sara Errani, a 2012 semi-finalist, was beaten by one of her best friends.
Williams, seeking her 17th Grand Slam title and fifth US Open crown, beat 77th-ranked Galina Voskoboeva 6-3, 6-0. Williams won the last eight games, breaking to capture each set, and advanced in 69 minutes.
"Galina played very well in the first set. You can see how much she has improved," Williams said. "But I played pretty well myself."
