2nd Round. a. Sue Barker beat Virginia Wade in San Francisco in 1977.
3rd Round. b. Hewitt defeated David Nalbandian in straight sets in 2002. Since then, Federer has won the event a men's-record eight times, and Djokovic has won it seven times, while Nadal and Murray each won it twice.
4th Round. c. Sharapova was 17 when she beat
Serena Williams in the 2004 Wimbledon final for the first of what would become five major trophies during her playing career. Williams also was 17 when she won the first of her 23 Grand Slam titles at the U.S. Open — but that was in 1999. Raducanu was 18 when she won the 2021 U.S. Open.
Quarterfinals. b. The only time he lost in Week 1 after winning the trophy the prior year was in 2016, when Sam Querrey defeated Djokovic in the third round. Djokovic's other five title defenses went like this: one semifinal loss (2012) and four championships (2015, 2019, 2021, 2022).
Semifinals. a. and c. Osaka, who currently is off the tour while pregnant, won the 2018 and 2020 U.S. Opens and the 2019 and 2021 Australian Opens, and she never has lost a match in the quarterfinals or later at any major tournament. Seles began her career with a 6-0 record in major finals and ended up 9-4.
