Venus Williams has extended her record run at majors by downing Swiss Stefanie Voegele in the second round of the Australian Open.

The 13th-seeded American won 6-3 6-2 on Wednesday to set up a clash in the round of 32 against either countrywoman Varvara Lepchenko or Duan Ying-Ying from China.

The 36-year-old Williams is playing in her 73rd grand slam tournament, two more than the previous Open era mark set by fellow American Amy Frazier.
