World number one Novak Djokovic survived a scare before beating Fabio Fognini in the second round of the BNP Paribas Open on Sunday.
Djokovic won all but one of the first 11 games before Fognini mounted an unlikely comeback, forcing a third set in which the Serb prevailed to take a 6-0 5-7 6-2 win at Indian Wells.
"I had a very bad game at 4-2, couple of unforced errors, got him back in the match. Next thing you know, we're one set all and a couple of tight games," Djokovic said.
"He's a good player on this surface. He loves playing on slow surfaces. He made me work. He made me earn my points. In the end, I have done what I needed to do."
Djokovic is unbeaten on the ATP Tour in 2013 with a 14-0 record, and remains the clear favourite to win the tournament for the third time following victories in 2008 and 2011.
Meanwhile, British third seed Andy Murray came from behind to defeat Russia's Evgeny Donskoy 5-7 6-2 6-2.
