Serena Williams' U.S. Open Final match against Naomi Osaka in September was marred by a one-game penalty assessed to Williams in the second set, overshadowing Osaka's 6-2, 6-4 victory.
Chair umpire Carlos Ramos assessed Williams multiple code violations near the match's conclusion, stemming from an argument over whether Williams had been given advice from the stands by longtime coach Patrick Mouratoglou.
Mouratoglou admitted to coaching Williams shortly after the match's conclusion, adding “Everybody does it — you all know it."
Now over a month after the tournament's dissapointing conclusion, Mouratoglou is calling for a reshaping of tennis' long-standing anti-coaching stnace.
