Serena Williams made history at the All England Club on Saturday, charging to her sixth Wimbledon title with a 6–4, 6–4 win over No. 20 Garbine Muguruza in the final. The victory moved her record to 21-4 in major finals and served as the final mark in completing the "Serena Slam," as she now holds all four major trophies with wins at the 2014 U.S. Open, 2015 Australian Open, 2015 French Open and now Wimbledon. Now with 21 Grand Slam titles, Serena is seven wins away from a historic calendar Grand Slam, or winning all four majors in one year, and will look to tie Steffi Graf's Open Era record of 22 Slam titles at the 2015 U.S. Open. How do the two great champions compare?

Comparing Grand Slam titles by age
While Graf and Serena both won their first Grand Slam titles at age 17, Graf's climb towards her current record was much quicker than Serena's rise on tour. At the age of 20, Graf had nine Slam titles while Serena had four. At the age of 24, Graf had 13 titles while Serena had seven. However, by the time Graf turned 29 she had already claimed her 22nd Slam title. Today, at age 33, Serena is still playing, winning titles and chasing Graf's Open Era record.
