Jannik Sinner progressed to the semi-finals of the Vienna Open with a dominant straight-set win over Alexander Bublik.

A single break of serve in both sets was enough for Italian world number two Sinner to maintain his pursuit of his fourth title of the year.

Four-time Grand Slam champion Sinner, who lost only five points on serve during the entire match, will face Australia’s Alex de Minaur for a place in the final.

The 24-year-old, dethroned as the top-ranked men’s player by Carlos Alcaraz following defeat by his rival in the US Open final, has won 60 of his past 66 matches.

World number 16 Bublik beat Sinner in Halle in June, but the Kazakh was no match for the Australian Open and Wimbledon champion on Friday.

Sinner never conceded more than one point in any of his service games, while applying consistent pressure on Bublik and managing to take two of his eight break points.

Sinner is on a 19-match winning streak on indoor hard courts and a seven-match winning streak in Vienna, having won this title on his previous appearance in 2023.
