American tennis star Frances Tiafoe issued an apology on Tuesday after he shocked fans when he blasted profanities at a chair umpire following his third round loss at the Shanghai Masters on Tuesday.
The U.S. Open semifinalist was upset by 61st-ranked Roman Safiullin in a 5-7, 7-5, 7-6 (5) loss.
Immediately after shaking hands, Tiafoe moved on to the official.

"F--- you, man," a visibly frustrated Tiafoe shouted. "F--- you. Seriously man, f--- you."
According to The Associated Press, Tiafoe shouted about 10 expletives in the direction of official Jimmy Pinoargote during a minute-long tirade.
He later posted an apology to his social media.
"I really apologize for the way I acted tonight. That is not who I am and not how I ever want to treat people," he said in a message shared to his Instagram Stories.

"I let my frustration in the heat of the moment get the best of me and I'm extremely disappointed with how I handled the situation. That's not acceptable behavior and I want to apologize to the umpire, the tournament, and the fans. I'll be better for y’all."
The outburst was seemingly in reaction to a time violation he received at 5-5 in the decisive tiebreaker. He was docked his first serve after Pinoargote found he was not making a genuine attempt to serve.
He lost that point and the next to lose the match.
