NEW YORK — We've all seen this before from Venus Williams. It's just been a while.
Serving well and hitting groundstrokes cleanly, Williams reached the U.S. Open quarterfinals for the first time since 2010, possibly setting up a showdown against her younger sister, by beating 19-year-old qualifier Anett Kontaveit of Estonia 6-2, 6-1 on Saturday.
It was about as quick and lopsided as a fourth-round Grand Slam match tends to get, taking only 50 minutes. The 23rd-seeded Williams won 21 of 25 first-serve points, faced merely one break point — saving it, in the last game — and committed just nine unforced errors, 12 fewer than her 152nd-ranked opponent.
