Serena Williams Golden Slam

After besting Russia's Maria Sharapova in the women's singles final match, Serena Williams not only won the gold, but also made history. Serena became the first tennis player since Steffi Graf in 1988 to complete a career Golden Slam — winning all major titles of the Grand Slam in addition to a gold at the Olympic Games. Although Serena already has two gold medals in doubles (with sister, Venus Williams), this is the first time the 30-year-old has achieved a singles gold.

Of her win and her comparison to tennis great Steffi Graff, Serena said, "Growing up watching her, I always liked her. Having a chance to be mentioned in the same name — I always thought, OK, one person I'll never be mentioned in the same name is Steffi Graf. She's done everything." Congrats are in order for Serena. Take a look back at how the tennis superstar made her way to the top of the podium and into the history books!
