Tennis LIVE: Grand Slam winner gets huge ban as Madrid Open star trolled by rival coach | Tennis | Sport

Taylor Fritz was heckled by a rival coach during a training session at the Madrid Open ahead of his match against Casper Ruud.

The incident took place on Monday and was captured in a viral clip on social media

Marat Safin, who coaches Andrey Rublev, grabbed a racket and stood on the other side of the court as Fritz practiced his serves.

His first attempt was sent crashing into the net, prompting a sarcastic response from Safin.

“Oh my God,” he yelled in mock exasperation before Fritz hit a second serve long and past the service line.

Safin, known for his fiery personality during his playing days, shouted at the American: “Go to practice, man!”

He then appeared to storm off in mock frustration to the delight of the fans in attendance.
