Serena keeps teen star quiet

Serena Williams silenced the loudest grunter in women's tennis as she made a confident start to her defence of the women's singles title at Wimbledon today.

The world number one gained a 6-0 6-4 first-round victory against Michelle Larcher De Brito, a 17-year-old from Portugal who was over-run at the start of the match but recovered to give the three-time champion something of a work-out in a competitive second set.
