Grigor Dimitrov smashed three rackets on his way to losing the Istanbul Open final to Diego Schwartzman.
Second seed Dimitrov was a set and 5-2 up in the second before the wheels came off in spectacular fashion - he only one won more game in the rest of the match.
Argentina's Schwartzman, the world No 87, fought back to win his first ATP title 6-7 (5-7) 7-6 (7-4) 6-0.
"I let myself down, I let my team down, I let my family down with that behaviour," Dimitrov said.
"I started cramping at 5-2 in the second set. It was very unfortunate that I couldn't close out the match. I have to give credit to Diego."
Bulgarian Dimitrov, the world No 29, lost 11 of the last 12 games, and he took out his frustration on three of his rackets.
The third racket was destroyed with the score at deuce, with Schwartzman 5-0 up in the third - and that resulted in a match-ending penalty.
Dimitrov later posted on Twitter: "I want to apologize to all my fans and audience for my behavior on court last night, big congrats to Diego, who played an incredible match!"
