Roger Federer equalled Rafael Nadal's record of 19 ATP Masters 1000 titles as he beet 11th seed John Isner 7-6 (9/7) 6-3 in the final of the BNP Paribas Open in Indian Wells.

The Swiss third seed became the first player to win four Paribas Opens, adding to the three he won between 2004 and 2006.

Federer saved two early break points and, after a rain delay, saw the set through to a tie-break which he took when Isner netted on Federer's fourth break point. With the first set secure, Federer upped the ante and lost just one point on serve in the second set, winning the last four games to clinically wrap things up.

It was a title that looked unlikely at times in the week with the former world number one having been taken to three sets by both Milos Raonic and Thomaz Bellucci.

"When it all pays off after a bit of a scare early on in the week and you get the title and the emotions are going, it's a wonderful feeling," Federer said on

"I remember the days when I won three years in a row here, and I enjoyed myself over here.

"It's been a long time since I have been this successful here, even though I have had some really good matches here in the past, but it's nice taking it all the way and getting victories. I was just really happy and not relieved because I was just extremely proud of my performance this week."

Federer's winning streak now stands at 15, having recently won ATP 500 tournaments in Rotterdam and Dubai.
