In an interesting turn of events, the Australian Open has been given permission to shorten the length of matches by implementing a tiebreak in the deciding set. Of course, other Grand Slams do the same thing; Wimbledon recently added a regular tiebreak at 12-12 in the final set.
Australian Open granted approval to use a "super tiebreak" to 10 points at 6-6 in final sets. Could be introduced as soon as 2019. If it is, all slams different:— Stuart Fraser (@stu_fraser) December 4, 2018
French Open - No tiebreak
Wimbledon - Tiebreak to 7 at 12-12
US Open - Tiebreak to 7 at 6-6 https://t.co/dwLbfZnzdR
But, unlike the US Open and Wimbledon, the Australian Open will add a "super" tiebreak where players will play to 10 points, instead of seven, still needing to win by two. Despite whether fans are for or against this addition, it is possible that the first Grand Slam of the year will not add the tiebreak just yet. Players will be consulted to see if the addition is wanted.
If the tiebreak is added, the French Open will become the only major without a tiebreak in the deciding set. And still the only one without a roof.
