Coco Gauff was frustrated by her mistake-filled performance during a first-round Wimbledon loss, but she is determined not to let negativity linger.

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

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.
