I had thought that Venus and Serena Williams had gotten tired of tennis and the exhausting and body-breaking discipline that is required to maintain top form. With multiple and recurring injuries, I had expected both of them to sort of hang up their rackets and focus their energy in their multi-million dollar investment portfolios.

But Serena proved me wrong today when she completely obliterated the new No. 1 ranked player in women's tennis in the final of the Australian Open Tennis Tournament.

Maria Sharapova never had a chance as she wilted before the blazing serves and ground strokes of a resurrected Serena Williams. The final score was 6-1, 6-2. The match took only 1 hour and 3 minutes to complete.

Serena spent last season on the sidelines with a serious knee injury and was ranked only No. 81 coming into the Australian Grand Slam event.

She proved to the world that her body and mind are still capable of playing tennis at the highest level.

When the Williams sisters were at their peak, they were like powerful locomotives crushing everyone else who dared to get in their way.

Today, one of those trains came roaring back with a vengeance. Women's tennis will be the better for it. Welcome back, Serena!
