Serena supreme; Williams wins eighth, and most unlikely, Grand Slam title

Serena Williams always takes handwritten notes onto the court, as useful reminders or for motivation.
This time, she wrote one word: Yetunde.

Memories of her slain half-sister inspired Williams to a 6-1, 6-2 win over top-seeded Maria Sharapova in the Australian Open final -- her eighth Grand Slam title, her first since winning here in 2005, and her most improbable.

"Usually I write, 'Look at the ball, move forward, do this, do that.' Today I just had one word. My note was just `Yetunde.'

"Every changeover I looked at it and I just thought about how happy she would have been ... about what an amazing sister she was to me. I just said, 'Serena, this has to be more than enough to motivate me.' And I think it was."
