Frances Tiafoe Cusses Out Umpire In Fiery Rant At Match, ‘F*** You, Man!’

Frances Tiafoe absolutely lost it on an umpire on Tuesday … cussing up a storm as he expressed his frustrations over a controversial call.

The tennis star lashed out following his loss to Roman Safiullin at the Shanghai Masters … clearly pissed off about how things unfolded earlier in the match.

During the contest, the umpire gave 13th-seed Tiafoe two time violations … the second one taking away Tiafoe’s first serve on a crucial point in the tiebreaker.

After shaking hands with Safiullin, Tiafoe set his sights on the ump … and let him know exactly what he thought.

“F*** you, man!” Tiafoe yelled while pointing at the umpire. “F*** you!”

“Seriously, man. F*** you! You f***ed me the f***ing match!”

The crowd was in a mix of shock and amusement watching it all play out … audibly reacting to the meltdown on the broadcast.

Tiafoe — who made the semifinals of the US Open in September — should expect a hefty fine for the F-bombs … as verbal abuse toward umpires is a violation, per the ATP.

Remember, Alexander Zverev was hit with a $40K penalty after calling the umpire a “f****ing idiot” and hitting his chair with his racquet in 2022.
