Serena Williams: Women have work to do to get equal pay

— -- NEW YORK -- After moving ahead of Martina Navratilova for the most Grand Slam match victories by a woman in the Open era, and tying Roger Federer's mark for all players, Serena Williams offered some thoughts on gender equality in sports.

"I definitely think there is a difference between the way male and female athletes are treated. I also believe that as a woman we have still a lot to do," Williams said Saturday after beating Johanna Larsson 6-1, 6-1 at the US Open for her 307th win at major tournaments.

"Tennis has made huge, huge improvements," she continued. "We just have to keep that ... going for all other female sports, as well."

At Wimbledon in July, when Williams was en route to her record-equaling 22nd Grand Slam title, a reporter asked her about being considered one of history's greatest female athletes. Her reply: "I prefer the words 'one of the greatest athletes of all time.'"

Williams' clothing and shoe sponsor is using that line as part of a marketing campaign during the US Open.

On Saturday, Williams said she thinks a priority for women's tennis should be closing the pay gap that still exists at non-major tournaments (the Grand Slam events hand out equal prize money).

"There is a huge pay difference in terms of male and female athletes in lots of sports," Williams said. "Still so in tennis a little bit, as well. ... It's just taking one step at a time."
