ESPN is marking the 40th anniversary of Title IX by unveiling the top 40 female athletes of the past 40 years.

Mia Hamm was just 15 years old when she became the youngest woman ever to don the jersey of the U.S. senior squad.

She wore that jersey for 18 years and scored 158 international goals, more than any player ever, and tallied 144 career assists, the most ever by an American player.

The No. 1 player in ESPN's countdown, Hamm appeared in the first four Women's World Cups, winning two of them -- including the mythic 1999 tourney on home soil. She also won gold in the 1996 and 2004 Summer Olympics.

"My motivation is not about personal gains," she once said. "I want to do as much as I can to get the sport out there."

She retired a winner, a legend and a symbol of what women's sports can be.
