In early September, 19-year-old Coco Gauff won the U.S. Open. She is the first American teenager to win the tournament since 1999, when 17-year-old Serena Williams took the crown.

Gauff has said Serena is the reason she plays tennis. She is her tennis idol, and for good reason. Serena Williams has won 23 Grand Slam titles – more than any player in the Open era. But before becoming a household name, Serena was a girl from Compton with a drive.

This week on "Making", Brandon Pope revisits the years before anyone knew Serena’s name. Hear from the people in the room and on the court during her evolution to tennis prodigy, including her sister Isha Price, former tennis pro Chanda Rubin, and childhood coach Rick Macci.
