Thursday's triumph over Halep marked the first American player since Serena Williams (in 2008) to knock off the defending Wimbledon champ at the US Open. She last reached the third round of a major at the French Open in 2014, which was her debut. 

Townsend will face Romania Sorona Cirstea on Saturday for a spot in her first Grand Slam fourth round.
