World number four Alexander Zverev had an underwhelming outing in the fourth round of the Australian Open against Milos Raonic earlier today.Coming into the clash, there were hopes this could be the Grand Slam Zverev would truly make his mark on the big stage following an impressive recent run of form.But his Canadian counterpart reminded everyone at the Rod Laver Arena exactly why he is still more than capable of competing with the best by comfortably beating Zverev in straight sets 6-1, 6-1, 7-6 [7-5].A total of ten double faults in the match hindered Zverev’s game with Raonic upstaging him in all departments to progress to the quarter-finals.With 57 minutes into the match, the scoring reading 6-1, 4-1 in favour of Raonic, emotions got the better of the German as he vented his frustrations on his racket as both players sat down between the change of ends.Much to the surprise of everyone present at the venue, Zverev smashed the racket repeatedly on the ground for almost about eight time till it was entirely mangled.Unsurprisingly, the 21-year-old earned a code violation warning from the chair umpire as a result.

Oh and here it is in slow-motion too:

With a new racket, he was able to put up a stronger showing in the final set but still came up short in the tie-break.

Raonic will now square off against either of Borna Coric or Lucas Pouille in the next round as he aims to better his 2016 Australian Open showing, his best till date.

Fans and experts, however, were critical of Zverev for his outburst, believing the youngster has to analyse his performance more astutely.

Despite being one of the most highly-rated prospects in the game, Zverev knows he needs to start becoming more consistent in the bigger tournaments over the course of the season.
