WATCH: Tiafoe unleashes on umpire following Kyrgios antics

Frances Tiafoe was very unhappy about Kyrgios' antics during the 2nd set tiebreak and he let the umpire hear it.

Unfortunately for Tiafoe, the antics got the better of him as he wasted 5 match points in the 2nd set tiebreak to lose the set. He ended up completely falling apart in the final set sending Kyrgios into the semi-final. Kyrgios and antics go hand in hand but Tiafoe was particularly annoyed by the umpire's handling of the situation.

Kyrgios has a habit of talking between points and sometimes that talk extends up to the moment when a players starts his serving motions. Some are bothered by it some aren't but it's not very sportsmanlike to do either way. It's especially ridiculous when Kyrgios complained about a fan distracting him from his servie in the 2nd set tiebreak.

Kyrgios kept talking about it out loud for a couple of points all of which were won by him. Tiafoe ultimately snapped when he sent a ball wide giving away the 2nd set. You see his reaction below.
