With all of that facing her, Osaka took to Philippe Chatrier against Tig and after saving a break point in the opening game of the match, she broke to take a 2-0 lead.

Now back on serve, the Romanisn watched helplessly as Osaka clambered through that game to break at love, sealing the set with a powerful forehand while moving forward.
Tig's serve was again under pressure in the second set, but she saved a break point to make the score 2-2. The Romanian had a real look at 4-4, 15-15, but a missed half-volley allowed Osaka to steal her momentum.
The Romanian would save a match point with a beautiful forehand down the line and she eventually holds to force a second set tiebreaker, which sees Osaka jump out to a 5-2 lead.
Tig would get back on serve after the second seed committed back-to-back unforced errors, but she ceded her two service points, giving Osaka a much-needed victory to calm the storm that has been surrounding her recently.
