Mardy Fish and
Bob Bryan were fined for promoting a betting website on social media and Fritz and Opelka reacted to it.
Both former players were part of the American Davis Cup team in a coaching rule which opened them up for this suspension. The International Tennis Integrity Agency issued a 10.000 dollar fine for both players and bans of four months after they mentioned a betting platform on Twitter and that's against the rules.
Fritz reacted to it on social media:
"Huh?!?! So tennis channel (and many others) can run special segments for draft kings, but as a coach you aren’t allowed to legally sports bet on another sport that has nothing to do with tennis ????"
Opelka also reacted:
"Tennis is stuck in the 1950s!"
