Williams Sisters Could Face Each Other in US Open Semi-Finals

Serena, 34, and Venus, 36, advanced to the fourth-round of the 2016 US Open.

Serena, 34, notched her 307th career Grand Slam singles victory when she beat Sweden's Johanna Larsson on Saturday. The world number one set the record for most ever singles victories in a Grand Slam tournament by a woman. She tied Roger Federer's record for most career singles wins in a Grand Slam tournament by any player.

After the historic win Serena said she just wants to keep the streak going.

Bouncing back from an upsetting loss at the Rio Olympic games and a recent shoulder injury, Serena said she feels like Wonder Woman playing the U.S. Open in hot pink compression sleeves for day matches and black ones for night sessions.

Sixth seeded Venus, 36, crushed her German opponent Laura Siegemund in straight sets on Saturday and fed off the momentum she gained on the court.

"When I got that match point I rode it all the way home," said the elder Williams sister after her win.

The superstar siblings have advanced to the round of 16 after strong wins on Saturday. The enduring symbols of American women's tennis could potentially face off in the semi-final if they both earn wins in their fourth-round and quarter-final round matches.
