He is yet to appear on Rod Laver Arena and his name is not as recognisable as the members of the "Big Four" in men's tennis, but little-known American Frances Tiafoe is making his presence felt at the Australian Open in more ways than one.
Tiafoe has become a crowd favourite after chopping down the likes of fifth seed Kevin Anderson on his way to the fourth round, however his post-match celebrations in the style of NBA great LeBron James are also winning over fans.
His five-set victory over the experienced Italian Andreas Seppi on Friday was followed by a James-like "Silencer' routine, as he ripped off his shirt, pounded his chest and raised his knees while sending the court three crowd at Melbourne Park into a frenzy.
"Another LeBron one today. Yeah, kind of just what he does," said Tiafoe of his celebration.
Tiafoe's animated celebration following his defeat of Anderson was also inspired by James.
The self-confessed "big basketball fan" lifted up his right shirt sleeve and then flexed and repeatedly slapped his biceps muscle much to the delight of the Margaret Court crowd.
"You like that?" a smiling Tiafoe replied to a journalist when asked about his amusing antics.
"It was pretty cool. I was talking with my boy Zach [Evenden] about it. Some celebration like you do for the new year.
"In the off-season, I'm more worried about winning tennis matches. It (the celebrating) is kind of instinct thing. I hope the crowd liked it."
The 20-year-old Tiafoe, who is the last American in the men's draw at the Open, looks up to James for more than his exuberant celebrations.
"Not just [is he] an unbelievable athlete, but what he does outside playing basketball," Tiafoe explained.
"The school he made, putting $50 million into that, that's unheard of. He's an absolute icon. Everything he brings, how he carries himself.
"Never having trouble with the media, never done anything wrong. He's a superstar for a reason. He's LeBron James for a reason."
Tiafoe is ranked 39 in the world and he is enjoying his best performance at a major to date.
His story is an inspiring one, as his parents emigrated to the United States from the west African country of Sierra Leone in the mid-1990s and he has previously spoken about his humble upbringing.
Tiafoe's introduction to tennis included hitting a ball against the wall when he was three and now he finds himself on the cusp of making the quarter-finals at a major.
He faces 20th seed Grigor Dimitrov in the last 16 and should he collect the scalp of the Bulgarian, who has reached at least the quarter-finals on three previous trips to Melbourne, he has promised something special after match point.
"If I get a chance to do it on a big court, big situation, you got to bring it up," Tiafoe said.
"It's not pre-med. I don't know what celebration I'm going to do. I got a lot of them that I know. Yeah, it kind of just happens."
