Super Serena eyeing date with destiny

Serena Williams' latest landmark achievement - an eighth Miami hard-court crown - sends the US superstar into the clay-court season surrounded by talk of an even greater feat - the calendar Grand Slam.

At 33, the world No 1 is playing as well as ever. In fact, she says she has a greater understanding of the game now, making her better able to use her astonishing power and array of shots to maximum effect.

"I actually think I read the game better," Williams says. "Like when I'm playing an opponent, after three games I'm like, 'OK, now I know what you're going to do' ... or when their coach comes out I really key in on what they change their games to.
