Serena Williams passed another landmark as she reached the quarter-finals of the US Open, but her sister Venus suffered defeat at Flushing Meadows.
The six-time champion swept aside Yaroslava Shvedova 6-2 6-3 to record her 308th Grand Slam match win, taking her past Roger Federer’s previous record for the most victories at major tournaments.
Serena was never seriously troubled by the 52nd-ranked Kazakh as she stayed on track for a 23rd Grand Slam title and will next face fifth seed Simona Halep.
Meanwhile, elders sister, Venus,suffered a heart-breaking fourth-round loss to Karolina Pliskova in New York.
The 36-year-old fended off three match points to force a tie-break, but Pliskova held her nerve to complete a 4-6 6-4 7-6 (7/3) win, which sent the 10th seeded Czech into her first Grand Slam quarter-final.
