Venus Williams cruised into her first U.S. Open quarterfinal since 2010.
The seven-time major champion routed 152nd-ranked qualifier Anett Kontaveit 6-2, 6-1 in 50 minutes Sunday to set up a potential meeting with her sister. Serena Williams faced fellow American Madison Keys next at Arthur Ashe Stadium.
The 19-year-old Kontaveit had played just two Grand Slam matches before this tournament, losing both, and was making her U.S. Open debut. She upset 31st-seeded Anastasia Pavlyuchenkova in the second round.
Kontaveit was clearly overmatched by the 35-year-old Williams. The Estonian had 21 unforced errors, including four double faults.
