Breaking into the ATP top 100 represents a daunting task for any aspiring tennis professional.
However, some manage to break through, as demonstrated by the presence of Carlos Alcaraz, Jannik Sinner and Daniil Medvedev.
In recent years, some extremely talented young players have breached the top 100, including Miami Open champion Jakub Mensik, Joao Fonseca and Learner Tien, who recently made the China Open final.
Another young talent, who has already tasted success at a major tournament, is set to enter the top 100 for the first time in his career.
Shintaro Mochizuki is set to enter the ATP top 100
Japanese star Shintaro Mochizuki is set to achieve a new career high following his latest victory at the Almaty Open.
After defeating Arthur Cazaux on Tuesday, Mochizuki stunned third seed Luciano Darderi on Wednesday, winning the contest 6-3, 6-3.
Consequently, he has gained 44 ATP points and is currently set to debut in the top 100 at a ranking of 92.
The 22-year-old’s talent has been well-recognised for a number of years. After all, he is a former ITF junior world number one and the only male Japanese player to win a junior boys Grand Slam singles title.
In the same year Mochizuki won the Wimbledon Boys Singles title, he led Japan to the Junior Davis Cup title.
Mochizuki’s big breakthrough at the professional level came in 2023, when he won his first three ATP Tour main draw matches to reach the Japan Open semi-finals, defeating Tomas Etcheverry, Taylor Fritz and Alexei Popyrin.
Fast forward to 2025 and Mochizuki will face American world number 36 Alex Michelsen in the Almaty Open quarter-finals.
Mochizuki doubles his number of ATP Tour main draw wins in 2025
Remarkably, Mochizuki’s two wins in Almaty have doubled his total number of ATP Tour main draw victories in 2025.
The former junior Wimbledon champion had won just two ATP Tour main draw matches heading into Almaty, at Wimbledon and the US Open.
At Wimbledon, Mochizuki came through three rounds of qualifying before defeating Giulio Zeppieri in a five-set thriller. He then lost a five-setter thriller to 17th seed Karen Khachanov.
In August, Mochizuki again won three rounds of qualifying before defeating Frenchman Hugo Gaston in the US Open first round. He then fell to eighth seed Alex de Minaur in straight sets.
Mochizuki’s 2025 ATP Tour main draw record stands at four wins and five losses.
