The Brazilian saved three set points in the first-set tiebreak en route to winning her first hard-court singles title against Zheng Qinwen, and then partnered Veronika Kudermetova to win doubles.

Putting her widely panned default behind her, she led her team a Grand Slam title.

The Japanese doubles specialist has been the center of an ongoing controversy that began when she accidentally struck a ball girl during her women’s doubles match on Sunday.

The tennis world has been critical of Sorribes Tormo and partner Marie Bouzkova, who were seen as pushing for a default after an errant shot from Kato struck a ball girl in doubles on Sunday.

After tournament referee Remy Azemar and Grand Slam supervisor Wayne McEwen went to Court 14 to look into what happened, Kato and her partner were disqualified.

Kato, a Japanese player, struck a ball at the conclusion of a point that inadvertently hit a ball girl at the back of the court.
