Simona Halep probably manage the biggest win on AO this season. The Romanian produced 3h 45 min long match vs American Davis, winning 2-1 into 3rd disader by 15-13. After the match, the Romanian have told that feels “dad”, out of energy, struggling with his wrists pain and that it hearts here a lot, at least at that time after the match. Also, world No.1 has started the AO with little injury as well.
From other side, Naomi Osaka plays a great Grand Slam. The Japanese managed 3 straight sets wins vs Kucova, Vesnina and Barty, playing outstanding tennis. She gain offensive tennis, good baseline player, powerfull and straight shoots, abilities which are sharing advantages even vs top quality players.
Overall, I see a very tough match for Halep. The mention details are only suggesting some advantages on opponent site. With such a good game plan, Osaka appears as eventual dangerious player, IMO. Even under this conditions, Osaka at previous H2H also pushed Halep under his limits. Osaka love under pressure matches, love playing vs top players. After everything that Halep suffered on last game, the Japanese here has everything to express some great efforts.
