4: First time Slam champions in the last six major tournaments - Simona Halep (2018 Roland Garros), Caroline Wozniacki (2018 Australian Open), Sloane Stephens (2017 US Open), Jelena Ostapenko (2017 Roland Garros). If Naomi Osaka wins today, she would become the 5th player to win her maiden Slam in the last eight majors.
