Nevertheless, Osaka showcased her skill by securing the initial set in a swift half-hour, subsequently progressing to a 3-1 advantage in the subsequent set.
She attained an additional break, elevating her lead to 4-2 when Ostapenko’s forehand landed in the net, and subsequently served for the match at 5-3.
However, her adversary, aged 28, thwarted a match point with a forehand directed across the court, reclaiming the break as Osaka’s forehand sailed past the rear boundary.
Ostapenko, conversely, faced another break to love in the decisive game, with the Latvian player’s backhand finding the net, thus concluding the contest after a duration of one hour and twelve minutes.
Great Britain’s Emma Raducanu is scheduled to compete later, as she faces off against American fifth-seeded player Amanda Anisimova.
