Sport’s most adorable pitch invader! The sweet moment a tennis player’s 18-month-old son escapes and toddles on to court to find his dad

Nicolas Jarry celebrated his victory in the fourth round of the Shanghai Masters on Tuesday with an invader on the court: his young son Juan.

The Chilean beat Diego Schwartzman 6-3, 5-7, 6-3 to book a quarter-final meeting with world number 19 Grigor Dimitrov, who eliminated top seed Carlos Alcaraz 5-7, 6-2, 6-4.

Jarry’s wife, Laura, and their sons, Juan, 18 months, and newborn Santiago, were on hand in Shanghai to cheer him on.

And as the world number 22 took a break after winning the match and signed the camera lens, Juan trotted onto the court to join him.

Jarry picked up his son and gave him a hug, before sitting him down in his pitchside seat, Juan clearly enjoying the experience and appearing unfazed by the new surroundings.

Nicolas Jarry was joined on the field by his 18-month-old son Juan on Tuesday.

Juan ran onto the court after Jarry beat Diego Schwartzman 6-3, 5-7, 6-3 to book a place in the quarter-finals of the Shanghai Masters.

Jarry’s wife, Laura, and their sons Juan and newborn Santiago, were present in Shanghai.

The adorable exchange was caught on camera, with commenters noting that Santiago could one day follow in his father’s footsteps.

Tuesday was a special day for Jarry, who turned 28 and reached the quarterfinals of an ATP Masters 1000 event for the first time in his career.

The Chilean was presented with a birthday cake and serenaded with a rousing rendition of “Happy Birthday” by tournament staff.

“I think it’s my third or fourth anniversary here in Shanghai,” Jarry told reporters.

“Usually I’m alone, very far from Chile, and the time zones are opposite, so usually I don’t have anyone to call, just in the morning or evening.

“So to be able to be with them is very special.”

The 28-year-old also credited his family with inspiring him to take his game to a new level.

“Since I was able to start a family, I was able to change the perspective a little bit bigger, bigger, with more sense of what is really important,” he explained.

“I’m trying to get strong with what it means to have a family, to have more motivation on the field or to have a bigger goal than just winning the matches.”

The world number 22 will face world number 19 Grigor Dimitrov, who beat top seed Carlos Alcaraz 5-7, 6-2, 6-4.

Jarry built up a decisive 44-17 advantage in the winners, but admitted he felt the match was slipping away from him after Schwartzman won the second set.

“I’m very happy to be able to come back after this second set,” he said.

“I was having a little trouble. I tried to push myself. It’s very hard to play against Diego because of (our) history.

“Mentally he is very strong, he is a great competitor and he succeeds in every ball. You have to work a lot and I am very happy to overcome it.
