While most of us were watching football on Sunday, Serena Williams was busy winning her fifth U.S. Open title, her 17th Grand Slam overall. 

Now 31 years old, Serena Williams has been wowing us with her phenomenal tennis play since 1995, when she turned pro. She and her sister, Venus, spent years at the top of the singles tour, like they also have been doing together on the doubles side.

Serena is currently ranked No. 1 in the world. With French and U.S. titles under her belt in 2013, could Serena be poised for tennis domination in 2014?
