Alexander Bublik claimed his first ATP Tour title with a stunning straight-sets victory over Alexander Zverev in the Open Sud de France final.

The 24-year-old went into Sunday's match without a career win over a top-five opponent and having lost two finals in a career-best season in 2021.

He was not to be denied this time, however, powering his way to a 6-4 6-3 win over the world number three in Montpellier in just one hour and 10 minutes.

The Kazakhstani lost just four points behind his first serve throughout the match, the only blip coming when he handed Zverev a break back to love after moving 3-2 ahead in the first set.

After regaining the advantage, Bublik survived two more break points before closing out the opener and the pressure only increased on the Zverev serve in the second set.

Bublik broke to love to lead 3-2 and again in the final game as Zverev's resistance wilted.

He can now look forward to rising to a career-high place in the rankings when the updated list is published on Monday.
