Federer favors faster play

Roger Federer took a thinly-disguised jab at old rival - and potential Wimbledon semifinal opponent - Rafael Nadal on Thursday when he demanded play be speeded up at the Grand Slams.

Seven-time Wimbledon champion Federer believes the sport is in danger of losing support and its appeal to TV viewers by the length of time it takes some players to serve at the start of a point.

The Swiss star's comments came just hours after Lukas Rosol complained Nadal was constantly going beyond the 20 seconds allowed between points at the Grand Slams during his second-round loss to the Spaniard.
