The world No. 1 arrived at Physioclinic in Milan on Tuesday morning and did not leave for four hours, accompanied by four members of his team.

The doctor who oversaw the appointment was reportedly called back from a holiday to attend.

Italian daily Gazzetta dello Sport framed the visit as routine management for a champion at the sharp end of a heavy season, and no fresh injury has been reported. Sinner left smiling shortly after midday.

It was the second precautionary stop in a week. Sinner had also visited J Medical in Turin, where he was photographed wearing a patch on his knee before training without discomfort.

Both appointments come days before he flies to the United States for the North American hard-court swing.

Paris collapse still shadows the season

The renewed focus on Sinner’s body traces back to Roland Garros in May, when the Italian collapsed against Argentina’s Juan Manuel Cerundolo in the second round.

Sinner had taken the first two sets 6-3, 6-2 and led 5-1 in the third when dehydration and dizziness took hold in a Paris heatwave that pushed temperatures above 30C.

He lost 15 points in a row, took a lengthy medical break and eventually went out in five sets.

TNT Sports commentator Jim Courier was scathing about the umpire’s handling of the timeout.

“This is absolute baloney,” Courier said on air, arguing the rules were being bent for a top player.

Sinner underwent testing in Milan before Wimbledon and was cleared.

He went on to lift his second consecutive Wimbledon crown in July, beating Alexander Zverev in the final for his fifth major overall.

No Toronto, top seed in Cincinnati

Sinner arrives in North America under close watch. He pulled out of the Canadian Open to protect his body, and the Cincinnati Open, which runs through 23 August, is now his only tune-up before Flushing Meadows.

His record at the Ohio Masters 1000 is uneven. Sinner won the title in 2024 but was forced to retire mid-match during last year’s final against Carlos Alcaraz.

“I am super, super sorry to disappoint you,” he told the crowd from courtside.

The Italian has still put together one of the most dominant seasons of his career, built around back-to-back Wimbledon crowns and a run of Masters 1000 wins.

Whether his body holds up through the New York fortnight is the question the run of clinic visits is designed to answer.
