Among the events in men’s tennis that should be decided in a best-of-five formats, you’d have to include the Olympic gold medal match.
But the ITF has decided to shorten it to best-of-three for the 2020 Games in Tokyo.
As well, all doubles matches will have match tiebreaks in lieu of third sets (in Rio, only the mixed did that).
The reason? To “reduce concerns of overplay for players who reach the latter stages of all three events – singles, doubles and mixed doubles.”
Note: only six of the 29 total men’s doubles matches in Rio went the distance.
