The hospital visit

Jannik Sinner arrived at Milan's San Raffaele hospital early on Monday 8 June for a series of clinical examinations programmed after his second-round exit from Roland Garros. The world number one spent approximately four hours undergoing tests before leaving in the late afternoon, greeting journalists with a brief "ciao, ciao" as he departed in a black van accompanied by Professor Alberto Zangrillo. He is expected to return on Tuesday 9 June to complete the second phase of the check-up.

What the tests covered

According to multiple Italian outlets, the examinations included blood chemistry tests, general and specific checks, and cardiological assessments. The full work-up is designed to investigate the causes of the physical distress Sinner experienced on 28 May against Argentina's Juan Manuel Cerundolo, where he lost 3-6, 2-6, 7-5, 6-1, 6-1 after collapsing physically when on the verge of victory in the third set amid searing heat at Roland Garros.

The search for 'silent inflammation'

Professor Andrea Bernetti, professor of Physical Medicine and Rehabilitation at UniSalento and secretary general of Simfer, outlined possible lines of investigation.

“The objective of the new tests at San Raffaele will probably be to analyse in a systemic and deep way how the entire organism responds to the chronic stress of the competitive circuit.”

Bernetti noted that, with obvious problems already excluded, doctors would likely use cutting-edge instrumental diagnostics alongside advanced laboratory tests that go well beyond normal blood work, potentially measuring substances produced by inflammation and evaluating hormonal balance.

Gut microbiome and pollen allergy

Bernetti also highlighted the intestinal microbiome as a possible area of inquiry.

“The intestinal microbiome could be altered by continuous time zones, changes in diet and competitive stress. A healthy intestine improves immune defences, reduces the risk of infectious diseases and improves overall health.”

He added that Sinner's pollen allergy, which affected him in Madrid in previous years, could prompt additional respiratory and allergological tests, noting that pollen and pollutant levels were very high in Paris during the match.

No immediate concerns

Early indications from the first round of tests are positive. Sources cited by ANSA and Fanpage report that no elements causing concern have emerged so far. The fact that the examinations were conducted openly, without secrecy, has been interpreted in sporting circles as a reassuring signal about Sinner's condition.

Road to Wimbledon

After a few days of rest in Sardinia with his girlfriend Laila, Sinner is expected to resume training in Monte Carlo on Wednesday 10 June. He will play no tournaments before Wimbledon, skipping the Halle event, as he targets a second consecutive title at the Championships.
