Coming off her second Grand Slam with a French Open title over Aryna Sabalenka last month, Gauff admitted her focus wasn't there against the unseeded Ukrainian after her straight sets loss. Gauff managed just six winners in the match, suffered nine double faults and whiffed her way to 29 unforced errors.

Gauff said after her shocking loss on Tuesday that she was “a little bit overwhelmed” with “everything” that came with winning her second major tournament last month. Gauff defeated Aryna Sabalenka in the French Open, and went on a mini media tour in the weeks following the victory.

Rick Macci, Boca Raton's wizard of tennis, was not surprised Gauff fell to 42nd-ranked Dayana Yastremska weeks after capturing the French Open.
