When Lady Luck smiles on you, it doesn’t matter if you’re facing the World No. 1 tennis player. Jiri Vaseley, ranked at present at no. 55, is still savoring the 6-4, 2-6, 6-4 victory he gained over Novak Djokovic at the Monte Carlo Masters this week; and maybe pinching himself to make sure it wasn’t a dream!

11-time Grand Slam champion Djokovic, lost to Veseley in his opening match of the tournament, marking his exit. It’s a point to note that Veseley has never, till now, beaten a top-ten listed player.

For Djokovic, it was the second time he’s been defeated by a player ranked outside the top 50. The last time was when he lost to World No. 74, Xavier Malisse back in 2010. Djokovic has won two of the Monte Carlo Masters titles in the last three years, so this upset came as a bitter shock.

With the French Open ahead of him (the only Grand Slam he hasn’t won yet), the setback will hopefully not hold back the Serb for long. Djokovic reached the final in three of the last four years at Roland Garros, but lost every time, twice to Rafael Nadal, in 2012 and 2014, and last year to Stanislas Wawrinka.
