Both coincidentally were docked the same amounts for the same offenses: $3,000 for coaching in the first round, another $4,000 for coaching in the fourth and an additional $1,500 for unsportsmanlike conduct.
Both are coached by their fathers. No coaching help is allowed during matches at Grand Slam tournaments.
Kenin, a 21-year-old from the U.S. who won the Australian Open this year and is seeded No. 4 in Paris, will face Petra Ktvitova in the semifinals Thursday.
Tsitsipas, a 22-year-old from Greece who is seeded No. 5, will play in the men’s semifinals Friday.
The good news for Kenin and Tsitsipas: The fine money comes out of their prize money, and reaching the final four in singles at Roland Garros this year is worth $500,000.
