Jack Sock meets ball kid Jessica Matthews after their collision during his semi-final alongside Mike Bryan at the Nitto ATP Finals on Saturday.

Sock Tackled By 'Line-backer' Ball Kid In London

American and ball kid relive comical incident

Jack Sock may have a future on the West End.

After the most minor of collisions with ballgirl Jessica Matthews during Saturday's doubles semi-final, Sock comically tumbled to the ground in one of finest acting performances ever seen at the Nitto ATP Finals.

He fooled no-one in the crowd, who enjoyed the gag, and was quickly helped back to his feet by partner Mike Bryan.  

As the first game came to an end, Matthews chased after a loose ball and attempted to return to the corner of the court. But she ran straight into Sock, who unknowingly walked directly into her path.

"I didn't know one of our ball kids was a line-backer for the Kansas City Chiefs," said Sock. "I was just being dramatic, it was playful and fun."

After Sock apologised to Matthews for his part in the incident, an equally apologetic Matthews summed up the unexpected experience with the reigning Wimbledon and US Open doubles champion.

"I was just very shocked at the time," she said.

Sock and Bryan advanced to the doubles final by beating Jamie Murray and Bruno Soares 6-3, 4-6, 10-4.
