Federer beats Chung Hyeon

World number one Roger Federer equalled his best start to a season when he beat South Korea’s Chung Hyeon to reach the Indian Wells Masters semi-final.

Federer, searching for a record sixth title, broke Chung’s serve four times as he won in one hour 23 minutes.

The win ensures that Federer will remain number one after the tournament is finished, while Chung will surpass Kei Nishikori as the highest-ranked Asian player.

Federer reached the final of all four Grand Slams in 2006, winning three and only losing the French Open to Rafael Nadal in four sets.
