The Serb has now locked in four Top 20 players for his four-city Balkan Tour.
Novak Djokovic‘s four-city Balkan Tour (known officially as the Adria Tour) has added another big name to its roster.

During a press conference on Monday the Serb announced that current World No.7 would join the field, which already includes Dominic Thiem, Grigor Dimitrov, Viktor Troicki and Djokovic himself.

“The phenomenal news is that Zverev is coming,” Djokovic said according to the website Tennis, adding that all the players will compete for free. “Three great world stars. I am really grateful to them and I am happy to be able to host them in my home town. Everyone comes here for free because of my relationship with them and the humanitarian character of the tournament.”

The first stop on the Adria Tour is in Djokovic’s hometown of Belgrade in mid-June. See the full schedule below.

The matches will be played on clay with short sets to four. Djokovic has still not decided about whether or not to use no-ad scoring. Zverev, Thiem and Dimitrov are all expected to play in Belgrade, but it isn’t yet known what the lineup for all events will be, or how many events each player will play.

“We don’t know who is in what form,” he said. “Zverev trained in America. Dominic has been active, working for several weeks. Clay is his favourite surface. I believe they will be motivated. We are professional tennis players, we miss doing our job.”
