No tennis player likes when a call goes against them, and plenty have responded in kind with tirades against the chair.

But few have gone out like Alex Bogomolov Jr. did last week at the $50,000 Nielsen Pro Tennis Champions in Winnetka, Illinois.

The 30-year-old Bogomolov, ranked as high as No. 33 in the world less than two years ago, is currently 83rd and just 0-3 in ATP level events this year.

Playing in the semifinals at Winnetka against American Bradley Klahn, and trailing 6-4, 4-6, 1-2, Bogomolov did not return a ball because a spectator called it out, costing him game point and dropping him behind 3-1 in the third set.

Stunned, Bogomolov approaches the chair and tells the official what happened. When the official does not relent, Bogomolov shakes his hand, then retreats to his area and puts up his rackets, takes his shirt off and leaves the stadium.

Klahn is shown visibly shocked, while Bogomolov gives the umpire a farewell message that definitely is not safe for work watching.
Klahn ended up losing the tournament final to Jack Sock.
