Wimbledon: Sinner tested but through against Borges

World number one Jannik Sinner was

tested but came through against big-serving 29-year-old world

number 48 Nuno Borges of Portugal in the second round of

Wimbledon Wednesday where the 24-year-old South Tyrolean

four-time major winner is looking to retain the title he won for

the first time last year.

Now the Italian will challenge American Jenson Brooksby (n.81

ATP) in the third round.

Sinner won in three sets 7-6 7-6 6-4 after Borges had served for

the second set.

"I'm very happy, the second set was tough, we have some things

to improve, we'll see," said Sinner after the match.

Sinner has come back after suffering a physical collapse

with dizziness and fatigue in the heat when on the verge of

victory over Argentine Juan Manuel Cerundolo in the second round

of the French Open in May.

Sinner who had been odds-on favourite at Roland Garros and was

one game away from beating Cerundolo before he ran out of gas

and suffered dizziness in the Paris heat, is also favourite to

retain his Wimbledon title due to the

injury-enforced absence of his great rival Carlos Alcaraz of

Spain.

Sinner had a barrage of tests at Milan's San Raffaele Hospital

recently and was cleared as fit to compete in South-West London,

possibly wearing a cooling vest between games.

Sinner has four grand slam titles to the seven claimed by

23-year-old Alcaraz, who missed Paris and is missing Wimbledon

with a wrist injury.
