Serena Williams' remarkable run in her final grand slam continued to gather pace on Thursday as she reached the US Open women's singles third round with a 7-6 (7-4) 2-6 6-2 triumph over Anett Kontaveit.

The record-breaking 23-time major winner may be set to step away from tennis following the conclusion of this year's event at Flushing Meadows, where she is also partnered with sister Venus in women's doubles.

But her latest victory arguably ranks as one of the most impressive she has racked up in recent years, with the record-extending stats underneath her win backing up her place in the sporting pantheon.

Williams has now won 367 matches in grand slam tournaments, comfortably extending her Open Era record for women's tennis and moving her within two of Roger Federer's outright record of 369.

In turning over Kontaveit, she also made it 10 victories against top-two seeded opponents in grand slam tournaments on the trot, last losing such a match at the 2007 US Open against Justine Henin.

In addition, it also brought up 100 US Open match victories when winning the opening set, with Williams having only tasted defeat on a further three occasions when striking first at this major.
