What is Serena Williams best known for?

Serena Williams is one of the most famous professional tennis players in the world, and a symbol for women’s empowerment — even for those fans who don’t necessarily follow sports.

Williams was a tennis prodigy from a very early age. By the time she was a teenager, she had risen to prominence in the sport, having left school in the ninth grade in order to pursue her tennis

career. As she continued her path to glory, Williams started racking up awards. Over the years, the athletic player has won 23 Grand Slam singles titles and to date, she holds the record for 13

Grand Slam singles titles on hard court. Williams is one of the highest-paid female athletes in the world and is one of the few professional sports champions to regularly make lists in Forbes.

She’s an all-around talent, bringing a level of physicality to tennis that is incomparable to this day. One of the keys to Williams’ long-term dominance, however, comes from her serve.

There are layers to William’s serving technique. The most impressive is, of course, her overall speed. Business Insider reports that her power serve averages 170 kilometers per hour (about 105 mph).

Accuracy is what makes switching to this serve so deadly in William’s hands. The ball spins out at the end of the arc, often crossing up her opponents in a direction Williams has full control over.

The final aspect of Williams’ serves applies to both her power and topspin approaches. This could be the underrated aspect of her game, that plays a big role in her many women’s singles title wins.

In spite of her massive success, Williams has remained humble, and when she isn’t on the court, she prefers to lie low with her husband and daughter.
