Wimbledon 2014: Federer has all the aces to flatten Muller

London: Sharp-shooter Roger Federer fired down 25 aces as he flattened Luxembourg`s Gilles Muller 6-3 7-5 6-3 under a closed Centre Court roof on Thursday to reach the third round of Wimbledon.

A year after perishing in a shock second-round defeat, the seven-times champion spared his legion of fans another dose of nail-biting drama as he produced a masterclass in serving.

Federer was greeted by a large red banner reading `King of Court` and he made sure he lived up to the proclamation as he dropped only nine points on serve during a 94-minute demolition job.

The Swiss next faces Spaniard Marcel Granollers or Santiago Giraldo of Colombia.
