Sachko upsets Bublik, Tien to meet Berrettini in Metz QFs
Ukrainian lucky loser Vitaliy Sachko earned the biggest win of his career on Wednesday at the Moselle Open, where he upset World No. 13 Alexander Bublik 7-5, 3-6, 7-5 to reach his first ATP Tour quarter-final.
The 28-year-old did not face a break point in the third set, according to Infosys ATP Stats, and pounced on his chance in the 12th game of the decider to triumph after two hours and nine minutes in Metz. With his win, he ended Bublik’s hopes of ending the year inside the Top 10.
Sachko is up 36 spots to No. 186 in the PIF ATP Live Rankings after becoming the first Ukrainian to reach a tour-level quarter-final since Sergiy Stakhovsky in Marseille in 2019.

In other action, Learner Tien defeated Tunisian lucky loser Moez Echargui 7-6(3), 6-3 to reach his sixth tour-level quarter-final of the season.
