The duel between Roberto Bautista and John Isner of the Miami Masters 1000 round of 16 left this unpleasant scene in which the Spanish faced a fan in the stands.
At the end of the second set, the Castellón tennis player he uttered to the fan that he did not stop encouraging Isner, in a very angry way, to “shut up the ***.” The chair umpire tried to stop the Spaniard and gave him a warning for his behavior.
Later, in that same game, his own chair umpire would warn the fan to stop their behavior.
