Valentin Vacherot maintained his impressive run at the Japan Open on Sunday with a victory over world No. 9 Arthur Fils in a three-set battle, securing his place in the semifinals.
Monaco’s tennis player found himself facing challenging positions throughout this quarterfinal, ultimately overcoming Fils 7-5, 4-6, 6-4 in Tokyo.
Fils took control of the match early, breaking Vacherot and earning opportunities to seal the opening set at 5-3. However, Vacherot refused to let the set fall out of reach as he saved both set points before shifting the momentum in his favour. Vacherot broke as Fils served for the set, winning four consecutive games and turning the set around to finish 7-5.
The top-10 player responded in the second set, finding the break before serving for the set at 5-4. Although Vacherot continued applying pressure, Fils held onto his lead to end the set 6-4 and force a decisive third set.
The final set found Vacherot chasing the match once again as Fils took a 4-2 lead, leaving little room for error. Vacherot responded by recovering the break, then taking control towards the match’s end, winning four consecutive games for the second time in the quarterfinal. With Fils serving to stay alive in the competition at 4-5, Vacherot earned match point and completed the victory to secure his position in the final four.
This was the second career match between Vacherot and Fils, marking Vacherot’s first win over the top-10 player. This victory marks a significant milestone for Vacherot as he has now reached his first ATP 500 semifinal, having previously reached the semifinals at the Shanghai Masters in 2025 and the Monte-Carlo Masters this year.
Vacherot will now face Czech world No. 23 Jiri Lehecka for a place in the Japan Open final on Monday. The two met in 2025, when Vacherot won 6-1, 6-3 in Paris. A win would send Vacherot into his first ATP 500 final ahead of his return to Shanghai to defend his title.
