BELGRAD -- World's third-ranked tennis player Dominic Thiem beat Filip Krajinovic 4-3 (7-2), 2-4, 4-2 to win the final match in the Adria Tour tennis tournament in Belgrade on Sunday.

Thiem had a hard time with Krajinovic in the first set but managed to win it after a tie-break.

Krajinovic, currently ranked 32nd in the world, surprised Thiem with a 3-1 lead in the second, and set the score even. However, his opponent showed more strength in the third set and marked a 2-1 victory.

The regional charity tennis tournament was staged here for two days from June 13-14 under a round robin system, in the organization of the world's top tennis player Novak Djokovic.

Djokovic missed the finals as he suffered a 1-2 defeat yesterday by Krajinovic and ended up as the second in the group, ahead of Alexander Zverev and Viktor Troicki.

Thiem's road to finals led across Damir Dzumhur (2-0), Dusan Lajovic (2-1) and Grigor Dimitrov (2-0).

The second leg of the Adria Tour will be held in Zadar, Croatia, on June 20-21, while the conclusion will take place in Bosnia and Herzegovina in early July.

Although a leg was also scheduled to take place in Podgorica, Montenegro, it was canceled on Saturday due to coronavirus protocol rules for entering that country.
