Cincinnati Masters champions on Monday Borna Coric and Caroline Garcia rose in the ATP and WTA rankings respectively.
Croatia’s Boric soared a remarkable 123 places in the ATP rankings after becoming the lowest ranked player to win a Masters 1000 title in Cincinnati.
The 25-year-old spent a year out of action with a shoulder injury which required surgery, before returning in March.
He arrived in Cincinnati as the world number 152 after spending much of his 2022 season on the second-tier Challenger circuit but is now ranked 29th.
Coric dropped just one set in the tournament, against 22-time Grand Slam champion Rafael Nadal in the second round, and beat Stefanos Tsitsipas in Sunday’s final.
Tsitsipas climbed two places to world number five, while Cincinnati semi-finalist Cameron Norrie jumped two spots to a career-high ranking of ninth.
Frenchwoman Garcia returned to the top 20 in the WTA rankings after beating Petra Kvitova to win the Cincinnati title.
The 28-year-old, who had slipped to 79th in the standings in May, is back in the top 20 for the first time since March 2019.
Garcia beat Kvitova 6-2, 6-4 in Sunday’s final to win her first WTA 1000 title since 2017.
Iga Swiatek retained her commanding lead as world number one despite losing to Madison Keys in the Cincinnati last 16.
