Insolite - When twin sisters play doubles at the Junior Australian Open

It's not unusual to see siblings blossom in the world of professional tennis, as the Williams sisters and the Zverev and Bryan brothers can testify.

A rather surreal confrontation took place in the doubles draw of the Junior Australian Open. Twin sisters Annika and Kristina Penickova took on Alena and Jana Kovackova, also sisters.

What's more, the sisters were dressed in the same outfit.

The Penickovas won 5-7, 6-1, 11-9 in the super tie-break to advance to the final.
