5 biggest upsets at the Miami Masters

Tommy Haas beat Novak Djokovic, 4R 2013

Djokovic committed so many unforced errors that he smashed his racquet on court in anger

Reigning champion and World No. 1 Novak Djokovic would have fancied his own chances at the Miami Masters against nearly any opponent, Roger Federer included, and had won the title in 2011 and 2012.

The older Haas, with significantly more experience than the Serb, was nonetheless at a different stage in his career and much lower-ranked than a younger, fitter Djokovic.

Djokovic was on a 14-match winning streak, and his 35-year-old opponent, who had been World No. 2 a decade prior, had appeared slightly nervous going into the match.

The German player would pull off the impossible – beat an in-form World No. 1 Novak Djokovic, and became the oldest man to do so in three decades. At the time, he was the oldest player in the top 50 in men’s tennis.

The victory took Haas to the quarterfinals in Miami for the first time in his career.
