Aryna Sabalenka eclipses Victoria Mboko to reach Australian Open quarter-finals

Aryna Sabalenka fought off one teenage challenger but finds another in her path to the Australian Open semi-finals.

World number one Sabalenka looked to be cruising to victory against 19-year-old Victoria Mboko at 6-1 4-1 only for the Canadian to show just why she is so highly rated.

Mboko saved three match points at 5-4 but Sabalenka regrouped and won a 20th consecutive grand slam tie-break in dominant fashion to claim a 6-1 7-6 (1) victory.

The stats don't lie
