INDIAN WELLS, Calif -- No. 2 seed Novak Djokovic, who is in the toughest quarter of the tournament, quietly advanced to the fourth round with a three-set win over Juan Martin Del Potro.
The defending champ took the first set 7-5 but Del Potro wasn't ready to pack his bags as he won the second set 6-4. Djokovic regrouped and lost only one game in the third set on his way to victory.
"The third set was the best tennis I've played this year probably," said Djokovic. "I'm just hoping I can carry this confidence, especially on the return, to tomorrow's match because I'm going to need that."
He next plays Nick Kyrgios, who won the battle of the next generation with a 6-3, 6-4 win over Alexander Zverev. Kyrgios upset Djokovic in the quarterfinals of Acapulco less than two weeks ago.
