Jannik Sinner continues to have questions circulate around him ahead of Wimbledon this year.
Sinner lost in the second round of Roland Garros this year, despite being the overwhelming favourite to win the title and leading Juan Manuel Cerundolo by two sets to love and 5-1.
After struggling with the hot conditions in Paris, Sinner has undergone medical tests to try and detect the cause of the issues he has been having.
These results came back positively for Sinner, but former Olympic champion Monica Puig still has concerns for him ahead of Wimbledon this year.
Monica Puig points out issue for Jannik Sinner ahead of Wimbledon
Puig was asked about Sinner’s recent difficulties in the latest edition of the Inside-In Tennis Podcast.
The Puerto Rican admitted her confusion at why Sinner struggled so much, as Puig pointed out how many other ATP players were competing in longer five set matches in the same conditions.
Where does Jannik Sinner’s defeat to Juan Manuel Cerundolo rank among the most shocking results in tennis history?
Puig then told Sinner’s team that this should raise alarm bells for them going into Wimbledon this year.
“For Sinner, I think I heard that he was doing a ton of testing in Milan to get his body right and figure out what’s going on,” said Puig. “That was also very unexplainable because he was cruising, he was doing extremely well and then just something changed and I saw it in the way that he was walking and I was like, this doesn’t look right.
“It was hot, but not horrible. It was US Open temps, it wasn’t Australia, so it was really weird that we were seeing what we were seeing what we were seeing, whether it was the heat or whether it was another issue, that’s something that his team needs to address, because it’s already a couple of times that it’s happened and he got lucky in Australia that they took that heat break that closed the roof, the AC helped him a lot, but there was no way that they were going to do that there because the temperatures weren’t enough to warrant the heat rule and also it was a beautiful day.
“So what happened? I don’t know. That’s up for him and his team to figure out. But in today’s tennis that it’s so physical and you have players who can go, I mean the amount of five sets, I’m not sure if they got close to tying the record or broke the record for most five sets in a major, that was unheard of.
So as a man entering the Grand Slam era, you need to be primed, prepped, ready to play potentially a five-hour match, six-hour match. We saw Rafa [Nadal] do it a ton of times. We saw so many of these players go the distance and still have enough left in the tank and that fifth set, so that’s already got to be sounding alarm bells in his team.”

Jannik Sinner’s alarming record in matches over three hours and 50 minutes
Roland Garros was the first time that Sinner had let such a dramatic lead go, but it is not the first time he has struggled in hot conditions.
It is also not the first time that Sinner has lost a Grand Slam match in five sets, and he actually has a very troubling record in matches that have lasted over three hours and 50 minutes.
Sinner has lost all nine matches that have taken this long, with the latest taking place at the 2026 Australian Open, when he was beaten by a then 38-year-old Novak Djokovic.

| Australian Open 2026 (SF) | 4 hours and 9 minutes | Novak Djokovic beat Sinner, 3-6 6-3 4-6 6-4 6-4 |
Three of these nine defeats for Sinner have come against his biggest rival Carlos Alcaraz, who will not be playing at Wimbledon this year as he continues to recover from his wrist injury.
Another potential positive for Sinner is that only one of these nine defeats has come at Wimbledon, having suffered with dizziness against Daniil Medvedev in the 2024 quarter-finals.
Many still see Sinner as the favourite for the Wimbledon title, and he will be hoping to bounce straight back to claim his first Grand Slam title of 2026, with the main draw of the grass court major beginning on Monday, June 29.
