Nadal blasts proposed rule

London: Rafael Nadal insisted Tuesday that plans by Wimbledon to introduce a 25-second shot clock will kill off the sport's capacity for epic Grand Slam confrontations. 

The US Open will have a shot clock for this year's tournament with Wimbledon poised to follow suit. World number one Nadal is routinely warned for slow play between points. 

Despite his objections, the All England Club insisted that a shot clock is on the agenda.
