Defending champion John Isner reached the Miami Open quarterfinals with a 7-6(5) 7-6(3) win over Britain’s Kyle Edmund on Tuesday, while Nick Kyrgios, in a loss to Brona Coric, was given a point penalty for an audible obscenity.
The obscenity by Kyrgios, who produced perhaps the shot of the tournament early in his 4-6 6-3 6-2 loss to 11th-seeded Coric, was apparently directed at a spectator. The penalty put him down a double break in the third.
It was the latest incident in Miami for Kyrgios, who had already made headlines for underhanded serves, a verbal spat with a spectator who was heckling him and firing off an expletive-laden rant at an umpire during a doubles match.
