To commemorate the conclusion of Women’s History Month, celebrated annually in the month of March, the U.S. sports network ESPN will dedicate a full day of programming to historic moments in women’s sports on Sunday, March 29, and both Serena and Venus Williams will play a starring role.

The programming block will begin at 4 a.m. ET on ESPN2, with an airing of Nine for IX: Venus vs., and run throughout the day. 

The film, produced by famed American filmmaker Ava DuVernay and released in 2013, chronicles Venus Williams’ fight for equal pay for women at Wimbledon that began in 2005.

Later in the programming block at 4 p.m. ET, the 2017 Australian Open final between the sisters will air in its entirety in commemoration of Serena Williams' 23rd Grand Slam singles title. It was the ninth Slam final to be played between the two, and the seventh won by Serena.

The victory allowed her to pass Stefanie Graf for the most women’s singles Grand Slam titles in the Open Era, and it was later revealed that she did so while in the early stages of pregnancy with her daughter, Alexis Olympia Ohanian, Jr. 

Earlier this week, six of Serena Williams' Grand Slam singles championships were featured in a marathon on the network, highlighting many more of her milestone moments.
