World No. 3 Dominic Thiem beat home crowd favorite Filip Krajinovic 4-3, 2-4, 4-2 at the final of Novak Djokovic's tournament as the world No. 1 broke down in tears in front of a packed 4,000 crowd on Sunday. 

Djokovic beat Germany's Alexander Zverev on Sunday in his last round robin match but failed to secure his place in the final after both players and Krajinovic ended up with 2-1 win-loss records and an identical 5-3 set difference in their section. 

"This tournament was for a good cause and we all gave our best," Thiem said after finishing off the weekend with a 100 percent winning record. 

"Many high quality matches in a great atmosphere, in front of a full crowd, so it was a perfect weekend," he added. 

Krajinovic, who stunned Djokovic on Saturday after losing to Zverev, squeezed through on the basis of having the best games differential among the three. 

At the end of his contest with Zverev, Djokovic shocked the spectators with an outpouring of emotions. 

"I am not crying because I got knocked out of the tournament, I am just overwhelmed by emotion because this reminds me of my childhood," the 33-year-old told the crowd as he received a standing ovation from his compatriots. 

"It's been an emotional few days and I want to thank everyone who made this possible. The important thing after this match is that we have one of our own in the final. I love you all and thank you so much for turning up.” 

The tournament is the first leg of the charity event called the Adria Tour, with the second leg taking place in Croatia's coastal resort Zadar next weekend. 

The third leg due in Montenegro on June 27-28 was canceled on Saturday over coronavirus concerns while the final leg is to be staged in Bosnia's Banja Luka on July 3 and 4. 

The world's professional tennis tournaments are still on hold due to the ongoing pandemic.
