Serena off to confident start

Serena Williams made a confident start to the defence of her Wimbledon crown, easing past fellow American Jill Craybas 6-3 6-3 in a first-round match lasting just 57 minutes on Centre Court.

The champion was not at her best, achieving only a 53% success rate with her first serve and coming up with 21 unforced errors, but she did not have to be against the world number 67.
