For Billie Jean King, 40 years after feats, women have 'so far to go'

BEVERLY HILLS, California (Reuters) - The two women who battled in Sunday's final of the U.S. Open tennis tournament earned prize money equal to their male counterparts and perhaps no person was more instrumental in bringing about that parity than Billie Jean King.

And yet, the 39-time Grand Slam title-winner is disappointed with the progress of equality 40 years after her groundbreaking achievements for women's tennis and the women's movement, perhaps most notably her defeat of Bobby Riggs in 1973's "Battle of the Sexes."
