Croatia’s Borna Coric soared a remarkable 123 places in the ATP rankings on Monday 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.
