Jannik
Sinner had a tense encounter with Frances Tiafoe at the 2021 Vienna Open, which
ended with the Italian criticizing his rival for being ‘disrespectful’ during
the match. The World No. 1 leads the head-to-head against the American 3-1, and
they will meet again tonight in the Cincinnati Open final.
The two
players first faced each other in October 2019, when an 18-year-old Sinner
defeated a 21-year-old Tiafoe at the European Open. A couple of weeks later,
the Italian repeated the win against Big-Foe, this time at the Next Gen ATP
Finals, where Sinner went on to become the champion.
Sinner’s past criticism of Tiafoe's tactics
However,
the real controversy came in 2021 when both were well-established on the Tour,
with Sinner ranked World No. 13 and Tiafoe No. 48. The American had surpassed
the qualifiers and made an unexpected run to the final, defeating the 7th seed
Sinner after a great comeback.

It seemed
like an easy victory for Sinner, who led 6-3, 5-3 and had the serve to close
out the match. However, Tiafoe began to take his time to get into position,
interacted with the crowd by clapping hands, and even talked while Sinner was
preparing to serve, helping him later to secure the win by 3-6, 7-5, 6-2 and
advance to the final.
“In my
opinion, today Tiafoe went too far, has done too much,” Jannik Sinner said
after the match. “It is one thing when the player tries to put on a bit of a
show, but it is quite another when you start to disrespect.”
When asked
about the match, Tiafoe commented: “I don’t really feel bad for that,” he
responded. “Look, I mean the crowd is there for a reason. I’m able to interact
with them, I’m able to do whatever.”

Sinner aims for a final win tonight in Cincinnati.
“I don’t
feel bad for that. I think he definitely had a chance to win the match
regardless. I used them to get on my side, and I started playing great tennis,
but ultimately I was just having fun out there, and it went my way.”
However,
Tiafoe added that they have a good relationship off the court and that he saw
Sinner's great potential as a player from the beginning: “I mean, when I played
Jannik in the Next Gen Finals and Antwerp back in 2019, I looked to my guys and
said, ‘This guy is going to be a Grand Slam champion,’” he continued.
“He’s going
to be on top of the game for a long time. We get along really well. I have
nothing but respect for that guy, how he goes about his process each and every
day. Well-coached with [Riccardo] Piatti, super humble guy for how young he is
and everything he’s accomplished so far,” Tiafoe added.

“Tonight, the result
was the result, but he’s got a great team behind him, he has a great work
ethic, he does everything right, he’s gonna win Grand Slams for sure. How many
I don’t know, but he’s going to have a hell of a career and probably be a Hall
of Famer at the end of it.”
On Sunday,
both players secured their places in the Cincinnati Open final, ensuring their
fifth meeting. Sinner defeated Alexander Zverev, and Frances Tiafoe overcame
Holger Rune, both enduring third-set tiebreaks before securing their spots in
the final.
After
Tiafoe secured his first Masters 1000 final, he was asked if he thought Sinner
would be the favourite in Monday’s final: “Absolutely, for sure he is, right?
He’s lost like [five] matches all year? He’s the favourite in every match he
plays, no question about it. You’ve got to tip your hat to a guy like him,”
Big-Foe commented on court.

- Jess is absolutely correct! But the disrespect is a trait I have noticed in most of the Russian players. Mirra is good but very immature and lacks humility. Conceivable needs to get a handle on that!Rapunzel05-11-2026
- Having spent weeks and weeks through the years on tour, I can say with confidence that Conchita was (is) one of the very few who realize the surprising level of maturity (and sometimes lack of) which Mirra seems to have developed in such a demanding adult world of Pro-Tennis. While at the same time reminding herself (Conchita, that is) that Mirra is still young and developing mentally and physically. The general public may forget at times, or not at all realize, these modern era young athletes do not have a 'normal' Youth. It's a major sacrifice, among countless sacrifices, these athletes must make. People who blow-off that fact are ignorant and unfair when they blurt out, "They choose fame so they have to put up with the intrusions on their lives". No, they do not.
mandoist05-11-2026 - Okay... someone with a camera was EAVESDROPPING on a private conversation. Shouldn't that be the point of discussion here? Regardless of the sensationalist crap by media, Pegula (and anyone) has a right to an opinion. There used to be an expectation that private conversations were respected, regardless of 'stardom' and whatever other defensive excuses media tries to shove in our faces. Boo-hoo if feelings are hurt. BTW: Having been employed at various tourney venues, etc., I can't tell you how nasty and offensive players can be when discussing their opponents and colleagues... in "private". Well, I could, but won't. I also challenge anyone to deny what Jessica said is false.

Bad enough the NHL allows Ovachenko (a Putin Supporter and Campaigner) to live and play in the USA. Let's not forget the STATE SPONSORED RUSSIAN DOPING PROGRAMS still in effect today.
