Montreal tennis standout Gabriel Diallo climbs 11 spots to 44th in ATP rankings

Canada's Gabriel Diallo jumped 11 spots to a career-high No. 44 in the ATP world men's tennis rankings after winning his first ATP Tour title over the weekend.

Diallo defeated Belgium's Zizou Bergs 7-5, 7-6 (8) in Sunday's final at the Libema Open, an ATP 250-level tournament in 's-Hertogenbosch, the Netherlands.

The 23-year-old from Montreal eliminated 20th-ranked Ugo Humbert of France in the semifinals and 22nd-ranked Karen Khachanov of Russia in the quarterfinals.

Diallo joined fellow Canadians Felix Auger-Aliassime and Denis Shapovalov in the top 50 of the rankings released Monday.

Auger-Aliassime, from Montreal, rose two spots to No. 27 while Shapovalov, from Richmond Hill, Ont., slipped one position to No. 31.

On the WTA Tour, 30th-ranked Leylah Fernandez of Laval, Que., was the lone Canadian in the top 50.

Ben Shelton rose two spots to No. 10 in the ATP rankings, joining No. 4 Taylor Fritz and No. 8 Tommy Paul to give the United States three men in the top 10 for the first time in nearly 20 years.

In April 2006, Andy Roddick was No. 4, James Blake was No. 7, and Andre Agassi was No. 10.

The 22-year-old Shelton, who won the 2022 NCAA singles title for the University of Florida, is only in his third full season on tour. He'd never traveled out of the U.S. until 2023.

Shelton is a two-time Grand Slam semifinalist, making it that far at the U.S. Open in 2023 and the Australian Open this January.

Fritz moved up three spots to match his career high after winning a grass-court title at Stuttgart, Germany, on Sunday. The top three men remained the same: No. 1 Jannik Sinner, No. 2 Carlos Alcaraz and
