PARIS — Venus Williams was unable to join her sister in the French Open quarterfinals, failing in a bid to get back to that stage at the clay-court Grand Slam tournament for the first time in a decade.

Finally back on court after her fourth-round match was postponed twice, the No. 9-seeded Williams lost to No. 8 Timea Bacsinszky of Switzerland 6-2, 6-4 on Wednesday.

Serena moved closer to her record-equaling 22nd Grand Slam title with a 6-1, 6-1 victory over 18th-seeded Elina Svitolina in only 62 minutes.
