Ignacio Buse added a double milestone to his breakout season on the ATP Tour by triumphing Sunday at the Winston-Salem Open.

With his title run in North Carolina, the 22-year-old Peruvian earned his first hard-court title at ATP Tour or ATP Challenger level, while he also secured his rise into the Top 30 of the PIF ATP Rankings for the first time.

ATPTour.com looks at the movers in the PIF ATP Rankings as of Monday, 31 August.

No. 30 Ignacio Buse, +6 (Career High)
Buse eased past Arthur Fery in Saturday's Winston-Salem title match to claim his second ATP Tour title after his ATP 500 triumph on the Hamburg clay in May. Now 22-16 for the season, according to the Infosys ATP Win/Loss Index, the Peruvian has risen six spots to a career-high No. 30 in the PIF ATP Rankings ahead of the US Open, where he opens against home hope Marcos Giron.

No. 33 Arthur Fery, +4 (Career High)
Despite final defeat against Buse in North Carolina, Fery can reflect on another solid week’s work in the wake of his Wimbledon semi-final run. After earning his first ATP Masters 1000 main-draw match win in Cincinnati earlier this month, the 24-year-old Briton followed that up by advancing to his first ATP Tour championship match in Winston-Salem. Fery has risen four spots to a career-high World No. 33 as a result.

No. 45 Juan Manuel Cerundolo, +6
Argentine lefty Cerundolo has returned to the Top 50 after just four weeks away following his quarter-final run in Winston-Salem, where the 24-year-old pushed eventual champion Buse to three sets before falling to defeat. It was the fourth quarter-final appearance at an ATP Tour event in 2026 for Cerundolo, who also memorably upset Jannik Sinner en route to the fourth round at this year’s Roland Garros.

No. 90 Martin Damm, +2 (Career High)
The 22-year-old Damm earned his first Top-10 victory by stunning Daniil Medvedev in the second round in Winston-Salem. American lefty Damm dropped just five points behind his first serve against former World No. 1 Medvedev before falling to Fabian Marozsan in three sets. Now up to a career-high World No. 90, Damm starts his US Open campaign against Frances Tiafoe.

No. 97 Benjamin Bonzi, +12
Frenchman Bonzi has surged back into the Top 100 after seven weeks away after reaching the last four in Winston-Salem. He took down his countryman Quentin Halys and Botic van de Zandschulp en route to the semi-finals at the ATP 250 before falling to Buse, and has climbed 12 spots to World No. 97 as a result.

Other Notable Top 100 Movers
No. 60 Adolfo Daniel Vallejo +1 (Career High)
No. 71 James Duckworth +8
No. 84 Aleksandar Kovacevic, +5
