WATCH: Controversial end to Hubert Hurkacz & Grigor Dimitrov's Miami 4R clash as Pole touches net on crucial point, throws racket in anger over call

Hubert Hurkacz and Grigor Dimitrov's fourth-round clash ended on a controversial note due to the Pole's crucial net touch in the tiebreak decider.

Dimitrov narrowly edged past Hurkacz 3-6, 6-3, 7-6(3) victory to advance to the quarterfinals of the Masters 1000 event in Miami. The Bulgarian next takes on a formidable opponent in Carlos Alcaraz, who claimed a 6-3, 6-3 win over Lorenzo Musetti in the Round of 16.

Grigor Dimitrov and Hubert Hurkacz's riveting clash took a controversial turn in the tense tiebreak decider when Hurkacz's left foot grazed the net while chasing down a drop shot from the Bulgarian.

The chair umpire was quick to call a net touch against the Pole, who appeared in disbelief over the call and threw his racket in frustration. The net touch proved pivotal, as it granted Dimitrov a crucial mini-break, giving him a 3-2 lead in the tiebreak.

The chair umpire attempted to quell Hurkacz's doubts about the call, expressing full confidence in his decision.

"One 100 percent. No doubt," the umpire said.

However, the Pole still requested to see the replay of the point, prompting the umpire to explain that there was no replay available. Nevertheless, the replay on the broadcast later confirmed that the World No. 9 had indeed made contact with the net, validating the umpire's decision.
