Atmane breaks into the top 100 and is named this week's most improved player, while Khachanov returns to the top ten.

On Tuesday, August 19, 2025, the ATP website released the latest PIF ATP rankings, highlighting this week's most improved players. Among them, 23-year-old French player Terence Atmane captured attention with a breakthrough performance in Cincinnati, reaching the top 100 for the first time.

As a qualifier at the Cincinnati Masters, Atmane powered through the draw, securing seven victories (including two in qualifying) and dropping only two sets. On his way to the semifinals, he defeated 15th seed Cobolli, Brazilian rising star Joao Fonseca, and two top 10 players, Taylor Fritz and Holger Rune. Although he eventually lost to world No. 1 Jannik Sinner in the semifinals, his impressive run propelled him up 67 places to a career-high No. 69.

"It’s just crazy, unbelievable."

That’s how Atmane described his journey in Cincinnati.

Besides Atmane, several other players also saw significant changes in their rankings.

29-year-old RussianKaren Khachanovreturned to the top 10 for the first time in over two years, now ranked No. 9 after climbing three spots thanks to his fourth-round showing in Cincinnati. He had reached the final in Toronto previously, and in Cincinnati, he defeated Valentin Royer and Jenson Brooksby before being forced to retire against Zverev in the fourth round due to back pain.

His career-best ranking was No. 8, achieved in 2019.

It’s worth noting that among Russia’s “big three,” both Medvedev and Rublev have dropped out of the top 10, making Khachanov’s resurgence especially timely.

Czech playerJiri Leheckaalso delivered standout performances, reaching the fourth round in both Toronto and Cincinnati. After defeating Adam Walton in the third round, he notched his 30th win of the season and rose to a career-high No. 21, which will be his ranking for the US Open.

18-year-old rising starJoao Fonsecashowed great promise during his Cincinnati Open debut, beating Bu Yunchaokete and Alejandro Davidovich Fokina to reach the third round before falling to the tournament’s breakout player, Atmane. Fonseca climbed to a career-high No. 44 and will make his main draw debut at the US Open.

French playerBenjamin Bonzihas been in excellent form recently. After upsetting Daniil Medvedev at Wimbledon in late June, he defeated Lorenzo Musetti in the second round at Cincinnati, notching his second Top 10 win in six weeks. He then overcame Tsitsipas to reach his first Masters fourth round, eventually losing to Auger-Aliassime. Bonzi’s ranking jumped 12 spots to No. 51, just nine away from his career-high.

Other notable movers inside the top 100 include:

No. 16Mensik(up one spot, a career high).

No. 19Cerundolo(up four spots).

No. 43Carabelli(up four spots, a career high).

No. 47, Spanish veteranBautista Agut(up six spots).

No. 48Lennard Jän(up seven spots, a career high).

No. 54Comesaña(up 17 spots, a career high).

No. 63Mattia Bellucci(up 11 spots, tying his career high).

No. 73, French veteranAdrian Mannarino(up 16 spots). No. 78Kamil Majchrzak(up 10 spots).

No. 83Luca Nardi(up 15 spots).

No. 98Dalibor Svrcina(up 17 spots, a career high).
