Novak Djokovic leads the men's ATP tennis rankings released Monday ahead of French Open champion Rafael Nadal and former world number one Roger Federer.
Despite winning his 12th French Open, Nadal remains in second while Barty's triumph helped her climb to No.2 behind Osaka.
After his five-set loss to Thiem, the world no.1 spoke about the semi-final that was played out in "hurricane conditions".
The winner will play Rafael Nadal in Sunday's final after the 11-time champion beat old rival Roger Federer 6-3, 6-4, 6-2
It is the second time since 2016 that all French Open play was cancelled and third since 2000.
The Serbian's bid to hold all four Grand Slam titles simultaneously for the second time remains alive.
He has been untroubled at Roland Garros this year, easing through in straight sets against Hubert Hurkacz and Swiss lucky loser Henri Laaksonen.
Djokovic, bidding to become just the second man to hold all four Slams at the same time twice, cruised to a 6-1, 6-4, 6-3 win over Henri Laaksonen.
Federer potentially needs to beat Tsitsipas, Nadal and world number one Novak Djokovic in order to come out on top.
Top-ranked Novak Djokovic was in control from the start as he beat 44th-ranked Hubert Hurkacz of Poland 6-4, 6-2, 6-2.
