Buse, Burruchaga building towards Top 100 debut at Montevideo Challenger

Two weeks and change remain in the 2025 ATP Challenger Tour season and players like Ignacio Buse and Roman Andres Burruchaga are battling hard to make their Top 100 debut in the PIF ATP Rankings.

Fittingly, Buse and Burruchaga are set for a semi-final showdown at the Uruguay Open, a rematch from their quarter-final meeting at the ATP 250 in Gstaad this year. That Gstaad last-eight outing marked the career-best runs at an ATP Tour event for both players.

In Montevideo, the 21-year-old Buse raced past Brazil's Gustavo Heide 6-1, 6-4 on Friday while Burruchaga upset second-seeded countryman Mariano Navone 6-4, 6-4.

Buse is No. 107 in the PIF ATP Live Rankings, just one spot behind Burruchaga, adding weight to their semi-final encounter. Whoever advances will likely need to win the Challenger 100 tournament to have a chance at cracking the Top 100 on Monday.

The Lima-native Buse won his first two Challenger titles this season (Heilbronn, Seville) and also qualified for his maiden major main-draw appearance at the US Open, where he fell to sixth seed Ben Shelton in the opening round.

Burruchaga is a six-time Challenger champion, with three title runs coming this year. The son of Argentina's famous former footballer Jorge Burruchaga, the 23-year-old returned to the winner's circle three weeks ago in Costa do Sauipe.
