The 33-year-old saved five of six break points to improve to 14-0 in third-round matches at the ATP Masters 1000 event after two hours and seven minutes. Djokovic struggled to take his chances in a hard-fought opener, but raised his level in the second set to maintain his perfect record of quarter-final appearances in the Italian capital.
Djokovic is aiming to break a tie with fellow 35-time Masters 1000 champion Rafael Nadal by lifting his 36th crown at the level this week. The World No. 1 equalled Nadal’s record Masters 1000 trophy haul last month by completing the Career Golden Masters for a second time at the Western & Southern Open. No other singles player has achieved the feat once.
The Serbian, who tied Pete Sampras’ tally of 286 weeks as the No. 1 player in the FedEx ATP Rankings on Monday, will face #NextGenATP Italian Lorenzo Musetti or Dominik Koepfer of Germany for a place in the semi-finals. Djokovic has not met either player at tour-level.
More than 10 years after their only previous ATP Head2Head contest in Belgrade, Djokovic and Krajinovic traded breaks to open their third-round clash on Centrale. Djokovic attacked his opponent’s forehand and attempted to break up play with drop shots throughout the first set, but could not execute that game plan when holding two set points at 5-4 on Krajinovic’s serve.
Krajinovic moved up the court well to finish points and establish a 4/1 lead in the tie-break, before Djokovic charged back by dictating rallies with his forehand and serving with added power. The 33-year-old converted his fifth set point when Krajinovic committed a forehand error. Both players won 61 points throughout the set, which lasted 87 minutes.
Djokovic found success early in the second set, driving forehands down the line to break serve at 1-1. The 17-time Grand Slam champion maintained his advantage to reach 5-3 and played with consistency from the baseline to break serve for a third time.
