Naomi Osaka took another confident step in her comeback from maternity leave by easing past Elisabetta Cocciaretto 6-3, 6-4 on Wednesday to move into the second round of the Miami Open, where another returning mother awaits.
Cocciaretto, ranked 51st in the world, represented a potentially tricky first test for Osaka with the Italian coming into Miami having won the WTA 125 event in Charleston last week.
But the step up in class proved too much as Osaka showed flashes of the form that carried her to four Grand Slam crowns, breaking Cocciaretto at the first opportunity while never allowing her opponent a break chance in the opening set.
