Novak Djokovic’s loss to Jiri Vesely in the Dubai Championships quarterfinals on Thursday was more costly than simply losing a match.
With the loss, Daniil Medvedev is set to take over the top spot from Djokovic in the ATP World Rankings. It will be the first time in 18 years that none of Djokovic, Rafael Nadal, Roger Federer or Andy Murray will hold the top spot.
