Stefanos Tsitsipas has replaced Rafael Nadal at No 3 in the latest ATP rankings.
The Greek is in Toronto this week where he will contest the National Bank Open.
The 22-year-old told the ATP Tour website on Sunday that moving to a career-high ranking was “a very good indication that I’ve done great so far”.
“[I am] just generally blessed that I’ve put in so much work to make it to the top three, which [I would consider] quite a special milestone.”
This year’s French Open runner-up said his main aim was to further improve.
“I wake up every single day with a goal: to get better. To get better with my tennis, to get better in the sport that I chose to follow in my life,” Tsitsipas added. “I’m very happy I get to play that sport. I’m very happy that I get to inspire people doing what I do.”
He will play either Frenchman Ugo Humbert or Italian Lorenzo Sonego in his first match at the Masters 1000 event in Toronto.
Nadal, meanwhile, moved down to No 4 in the rankings.
The Spaniard will open his account against either Lloyd Harris from South Africa or a qualifier on Wednesday.
Harris beat Nadal at the ATP 500-level event in Washington DC last week.
Elsewhere, the top 10 remains the same, with Novak Djokovic leading the charge and Roger Federer, who turned 40 on Sunday, at No 10.
