World No. 1 Novak Djokovic lost his semi-final clash against Spain’s Roberto Bautista-Agut 6-4, 6-4 at Shanghai Masters on Saturday. Djokovic couldn’t control his emotions, as he smashed his racket after losing the first set and then took a towel to sweep up the pieces himself. He even ripped his shirt open in anger during another point.

He also got into an argument with the chair umpire Carlos Bernardes constantly. “(Bernardes) was the star of the show,” he said. “That’s what he wanted to be today,” said Djokovic in the post-match conference. “This is one of those days,” Djokovic said. “Things go in an opposite direction than you want them, but again, it’s a lesson. Every day is a lesson.”

Djokovic had lost to Sam Querrey at Wimbledon, first round loss at Rio Olympics to Juan Martín del Potro and a US Open final to Stan Wawrinka.

Bautista-Agut won his first match against Djokovic in six attempts. He will face the winner of the second semi-final between second-seeded Andy Murray and Gilles Simon.
