VIDEO:Tiafoe attempts to pants Fritz during United Cup interview: "Dude, I will knock you out"

Frances Tiafoe jokingly tried to pants Taylor Fritz during his post-match United Cup interview and Fritz reacted to it by saying he'll knock him out.

All of that was done in light spirit and in a joking manner as the American team was in high spirits following the win over the Czech Republic. Fritz was talking to the reporter when Tiafoe approached him and jokingly tried to pants him to which Fritz turned around and jokingly said:

"Dude, I will knock you out."

The reporter played in on the teasing asking Fritz if he could to it and he responded:

"Yeah one punch, he's out."

The American later reacted to the TennisTV video of the interaction by writing:

"Fun Fact - @FTiafoe has actually pantsed me in public before... when he grabbed my shorts there I thought it was all over."
