MONACO — An erratic Novak Djokovic suffered a surprise 6-3, 4-6, 6-2 defeat against Daniil Medvedev in the Monte Carlo Masters quarterfinals Friday.
The 10th-seeded Russian was appearing in the last eight of a Masters tournament for the first time but was not overawed. In fact, it was the top-ranked Djokovic who made the most mistakes. The two-time champion looked out of sorts in tricky conditions and produced 47 unforced errors.
''On a windy day like today, conditions are changing every game,'' Djokovic said. ''It's tough to find rhythm and he doesn't give you much rhythm. He was very patient and played well tactically.
