The Australian tennis star's aspirations of reaching the ATP Finals last four are dangling by a slender margin after a gut-wrenching defeat in three sets to Italian opponent Lorenzo Musetti.
The world No 7 succumbed 7-5 3-6 7-5 after failing to serve out the match, keeping the Italian to remain in the event and now forcing the Australian needing to convincingly beat Taylor Fritz in his last group match to qualify for the semi-finals.
But facing Fritz in 48 hours is the least of de Minaur's pressing worries as the Sydneysider admits he must address the mental demons that threaten to cruel his career.
A loser of all six of his grand slam quarter-final appearances, the twenty-six-year-old was unable to disguise his distress after suffering yet another high-stakes near miss with his finals destiny in his own hands.
"I don't know how many times I can deal with a loss like this one," de Minaur stated in Turin. "I just have to talk to my team and try to sort out these issues because these are challenges that can't keep happening."
"I mean, if I really want to be serious about advancing to the next level in my career, these matches, I must win them. I just can't. It seems as if I've lost a lot of them this year. More than anything, it's getting to a point where psychologically it's killing me."
Describing his emotions as "quite dark", de Minaur lamented a succession of third-set slip-ups in 2025 and said he must find a way to win the close matches.
The Australia No 1's run of crushing losses comprise:
"I continue investing everything into these matches," de Minaur said. "When the outcome isn't positive, it's difficult to keep persevering."
"It's something that if it doesn't get sorted, it's going to consume me completely. I must get it sorted quickly rather than delayed."
De Minaur and Fritz are 5-5 in past meetings, though the sixth-ranked American emerged victorious in their meeting in this prestigious tournament last year.
The Australian's hopes remain flickering after Fritz suffered a 6-7 (2-7) 7-5 6-3 defeat to Carlos Alcaraz that ensured the Spaniard would progress to the semi-finals as the winner of the Jimmy Connors group.
The world No 2's win, having already knocked over de Minaur, put Alcaraz a single victory away of securing the season-ending top ranking from Jannik Sinner.
Even if he is defeated by Musetti in his final group match, Alcaraz will regain the world No 1 ranking except if Sinner, who defeated Auger-Aliassime in his opener on Monday, goes undefeated to retain his ATP Finals title.
"I'll attempt not to focus on it," said Alcaraz. "This will represent a extremely important match for me. I will try not to let the anxiety play a negative role in the match. I will think about my objectives, about feeling much better than today."
