The last time Fabio Fognini left the U.S.T.A. Billie Jean King National Tennis Center, he departed in shame.

A year ago, Fognini, a 31-year-old Italian, was expelled from the U.S. Open before his third-round doubles match after it came to light that he had verbally abused the chair umpire Louise Engzell during a first-round singles loss to his fellow Italian Stefano Travaglia.

Fognini reportedly used misogynistic slurs in Italian against Engzell, a respected chair umpire from Sweden.

Fognini was charged with three violations of the Grand Slam code of conduct and fined $24,000 of the $72,000 he earned in singles and doubles. When he left the grounds after learning his fate, he was so unnerved that he forgot to inform his doubles partner, countryman Simone Bolelli, who was waiting for him on the practice court.
