(Reuters) - World number one Andy Murray has voiced his support for changes designed to speed up tennis being tested at the inaugural Next Generation ATP Finals in Milan this November.
The tournament for the leading tour players aged 21 and under will feature a new scoring system, no lets, limited medical time-outs and shot clocks as the men's governing body seeks ways to appeal to younger audiences.
