The Greek is on his way back to the Top 50 after a title run in Gstaad.
Stefanos Tsitsipas has arrested his rankings freefall, thanks to a title run in Gstaad over the weekend.
The Greek, who defeated Raphael Collignon in the final in the Swiss alps on Sunday, rises 34 spots to No.51. The former World No.3 won his first title in 16 months.
Tsitsipas, 28, dropped outside of the Top 50 in March for the first time in eight years. He struggled with a back issue for much of last year but has been in good health in 2026.
Collignon, 24, rises another five spots after reaching his first ATP final. The Belgian comes in at No.37 this week, a career high.
Daniel Merida, 21, also claims a career-high slot after winning the Umag title on Saturday. The Spaniard, who defeated Damir Dzumhur in the final, jumps 23 spots to No.59. 34-year-old Dzumhur rises 21 spots and makes his return to the Top 100 at No. 87.
