Novak Djokovic battled back from a set and a break down to beat Laslo Djere in his opening match of the ATP event in Belgrade on Wednesday, avoiding a third consecutive defeat. The world number one trailed 4-3 in the second set but won a dramatic encounter against his fellow Serb 2-6, 7-6 (8/6), 7-6 (7/4) after three hours and 21 minutes. The 20-time Grand Slam champion is playing in just his third tournament of the season after being deported from Australia before the Australian Open over his Covid vaccination status. Djokovic also missed the Indian Wells and Miami Open events in the United States. After a surprise quarter-final exit to unheralded Czech Jiri Vesely in Dubai in February, he returned at the Monte Carlo Masters last week but lost to eventual runner-up Alejandro Davidovich Fokina in his first match.
