Lorenzo Sonego fended off the challenge of Alexander Bublik to win Sunday's Moselle Open final and earn a return to the top 50 in the world rankings.

In Metz, France, unseeded Italian Sonego swept to a 7-6 (7-3) 6-2 victory in the trophy match, collecting the third ATP title of his career.

He enjoyed a stellar week at the ATP 250 event, following up wins over Gilles Simon and Sebastian Korda with a semi-final victory against second seed Hubert Hurkacz, not dropping a set across his four matches.

Sonego, who reached a career-high ranking of 21st in February, had drifted to 65th in the months since, but the ATP said he would climb back into the top 50 as a result of his title run. The ATP's live rankings on Sunday showed him making a leap of 20 places to number 45.

Bublik, the seventh seed, had reached the final after Stan Wawrinka withdrew from their semi-final due to injury. He kept pace with Sonego on Sunday in a tight first set where serves dominated and neither man could force a break, with success for the Italian in the tie-break breaking the resistance of his Kazakh opponent.

The second set proved to be one-sided as Sonego added the title to his previous triumphs on tour, also extending his winning head-to-head record against Bublik to 4-0.

This indoor hardcourt success followed previous wins on grass in Antalya in 2019 and on clay in Cagliari last year.

Sonego said in an on-court interview: "This is a really emotional moment for me. I'm really happy because I played my best tennis this week. It's been a tough year and I want to enjoy this moment."
