The WTA will shorten matches this weekend by implementing a final set tie-break, while the ATP Cup will also resume on Friday.

Should scores be level after two sets, female players will play a first to 10 point tie-break instead of the traditional deciding format.

In a race against time, Margaret Court Arena will host no fewer than eight women’s matches on Friday – with the world’s top five players all in action.

Tennis fans will be able to see the likes of Nick Kyrgios and Stan Wawrinka on the 1573 Court – with those players each scheduled to play more than once should they win their first encounter.

ATP matches will continue in their usual format, with deciding sets played in typical fashion. (Simon Cambers)

ATP Cup back, but no Nadal

The ATP Cup will also resume on Friday after a one-day hiatus.

As reported by Tumaini Carayol, the final group stage clashes will be played on Rod Laver Arena, with one notable exception.

Strangely, the Group D clash between Argentina and Japan is not on the schedule.

The match is a dead rubber, with Russia already confirmed as group winners, and may have been left out as a result.

Yet, with ranking points on the line, its omission is still curious.

Rafael Nadal will also be on the sidelines on Friday (back injury), with Roberto Bautista Agut again deputising against Stefanos Tsitsipas.

The ATP Cup was scheduled to conclude on Saturday, but it seems that it will now be delayed by a day.

The Australian Open is still expected to start on Monday.
