Serena Williams won her 21st Grand Slam on Saturday with a win over Spain’s Garbine Muguruza, who was five years old when Serena won her first major. With the American superstar just one Slam away from tying Steffi Graf for the all-time record, FTW ranked all 21 of Serena’s Slams, from least impressive to most impressive, keeping in mind that every Slam is feat in itself. (The total number of Slams at each of the four majors is in parenthesis.)
