It means all matches across the men's and women's singles are now best of three sets with tiebreakers. In another alteration, the men's and women's doubles matches will have a Champions Tiebreak to 10 points when the score is 1-1 in sets, like in mixed doubles.
The International Tennis Federation announced the changes on Wednesday, saying they "reduce concerns of overplay for players who reach the latter stages of all three events — singles, doubles and mixed doubles."
They will come into effect for the 2020 Games in Tokyo.
