Germany’s Philipp Kohlschreiber stunned Australian Open champion Novak Djokovic 6-4, 6-4 on Tuesday, claiming his first career win over a world No 1 player to reach the fourth round of the ATP Indian Wells Masters.
Djokovic, who lifted a record seventh Australian Open title in Melbourne, had won eight of nine prior meetings with Kohlschreiber, but could find no answer to the 39th-ranked veteran, who had come up empty in 11 prior attempts to beat a top-ranked rival.
In match that resumed after rain stopped play just one game in on Monday night, Djokovic showed his frustration after dropping the first set by banging his racquet against his foot until it crumpled.
His fortunes still didn’t improve as Kohlschreiber opened the second set with a break.
Two wayward forehands and a double fault from Djokovic helped Kohlschreiber to another break for a 5-2 lead.
Then it was Kohlschreiber’s turn to show some nerves as a string of four errors, including a double fault, gave Djokovic a break back.
He made no mistake on his second chance, however, firing a sideline-skimming forehand to seal the milestone win on his first match point.
Kohlschreiber will face France’s Gael Monfils for a place in the quarterfinals.
World No 2 Rafa Nadal stayed on track to improve his record 33 Masters titles as he swept past Argentine Diego Schwartzman 6-3, 6-1 to reach the last 16.
Nadal took his record against the world No 26 to 7-0 in emphatic style, never facing a break point in a match lasting an hour and 16 minutes.
The Spanish superstar, a three-time winner of the Indian Wells title, next faces Serbian qualifier Filip Krajinovic, who ousted 14th-seeded Russian Daniil Medvedev 6-3, 6-2.
Fourth-seeded Roger Federer eased through with a 6-3, 6-4 victory over friend and fellow Swiss Stanislas Wawrinka.
Federer took his record to 22-3 over Wawrinka, a former world No 3 who is climbing back up the rankings in the wake of double knee surgery.
The Swiss maestro next faces Britain’s Kyle Edmund, who beat Macedonian qualifier Radu Albot 6-3, 6-3.
Poland’s 67th-ranked Hubert Herkacz upset sixth-seeded Kei Nishikori of Japan 4-6, 6-4, 6-3 to reach the last 16 of a Masters 1000 event for the first time.
He will play 19-year-old Canadian Denis Shapovalov, the 24th seed who beat 10th-seeded Croatian Marin Cilic 6-4, 6-2.
