Jannik Sinner answers if Stefanos Tsitsipas loss was reason for Riccardo Piatti split

In February, Sinner stunned the tennis world when he announced he was parting ways with his long-time coach Piatti. 

Piatti is a renowned tennis coach, who has coached Grand Slam champions and former world No. 1s. 

Piatti guided Sinner to multiple ATP titles and a top-10 ranking but the 20-year-old Italian decided to end their partnership at the start of this season. 

Sinner stood no chance versus Tsitsipas in the Australian Open quarterfinal as the Greek handed him a straight-set defeat. 

It turned out to be the last match of the Sinner and Piatti partnership. 

In Rome, Sinner was asked if the Tsitsipas loss was the reason why he fired Piatti. 

“I don’t really want to talk about it again, but the defeat with Tsitsipas is not the reason for the break with Piatti. After the victories and the defeats it is always important to make an analysis. The choice came later and I would say that in seven years with Piatti I have won many matches,” Sinner said, per Lorenzo Ercoli. 

Sinner now working with Simone Vagnozzi

After splitting with Piatti, Sinner hired ex-Italian tennis player Vagnozzi. 

Since hiring Vagnozzi, Sinner has stated several times that he is happy with what Vagnozzi brings to the table. 

This week in Rome, Sinner is having a promising campaign.

On Thursday, Sinner saw off Serbian Krajinovic 6-2 7-6 (6) in the Rome last-16. 

Sinner made a fast start to the match, breaking Krajinovic in the third and fifth games to open a comfortable 5-1 lead. 

In the eighth game, SInner routinely served out for the first set.

After winning the first set, Sinner broke Krajinovic in the opening game of the second set. 

Down by a set and a break, Krajinovic refused to quit and he broke back Sinner in the fourth game. 

As no more breaks were seen, the second set went into a tie-break. 

There, Sinner failed to convert his first match point at 6-5 but realized his second match point at 7-6.
