Cerundolo/Etcheverry stun top seeds at Canadian Open, reach Montreal doubles semis
Synopsis
Francisco Cerundolo and Tomas Martin Etcheverry — two singles specialists — have gatecrashed the elite doubles bracket at the Canadian Open, eliminating both the defending champions and the world's top-ranked pair in consecutive rounds. It is one of the more unlikely semifinal runs at a Masters 1000 event this season.
Key Takeaways
Francisco Cerundolo and Tomas Martin Etcheverry defeated top seeds Harri Heliovaara and Henry Patten 6-3, 6-4 on 12 August to reach the Canadian Open doubles semifinals.
The Argentine pair had previously eliminated defending champions Julian Cash and Lloyd Glasspool in the opening round.
Heliovaara and Patten had already won five tour-level titles this season — in Adelaide, Doha, Dubai, Madrid, and Wimbledon.
French duo Theo Arribage and Albano Olivetti saved two match points to beat Bhambri/Venus 7-6(5), 5-7, 11-9 and reach the quarterfinals.
Arribage and Olivetti, ranked seventh in the PIF ATP Live Doubles Rankings, are targeting a spot at the Nitto ATP Finals (15-22 November).
Francisco Cerundolo and Tomas Martin Etcheverry continued their remarkable doubles run at the Canadian Open in Montreal on Tuesday, 12 August, defeating top seeds Harri Heliovaara and Henry Patten 6-3, 6-4 to advance to the men's doubles semifinals. The Argentine pair, far better known for their singles careers, have been one of the standout stories of the week at the ATP Masters 1000 event.
A Statement Win Over the World's Best Doubles Team
Cerundolo and Etcheverry did not merely advance — they dismantled the joint No. 1 pair in the PIF ATP Doubles Rankings in straight sets. Heliovaara and Patten came into the quarterfinal having already claimed five tour-level titles this season alone, lifting trophies in Adelaide, Doha, Dubai, Madrid, and at Wimbledon. A sixth was firmly in their sights before the Argentines intervened.
Building Momentum Round by Round
The victory was no fluke. In the opening round, the Argentine duo had already dispatched defending champions Julian Cash and Lloyd Glasspool, signalling their intent early. Beating the top seeds in the quarterfinals now sets up a semifinal appearance for a pair that entered the draw as relative unknowns in the doubles format. Notably, this is the kind of crossover singles-to-doubles impact that rarely sustains beyond the first round at Masters level.
French Pair Arribage and Olivetti Also Advance
Elsewhere in the draw, Frenchmen Theo Arribage and Albano Olivetti produced a dramatic comeback on Sunday, saving two match points to defeat Yuki Bhambri and Michael Venus 7-6(5), 5-7, 11-9 in the Match Tie-break. The pair secured their place in the quarterfinals — their first at an ATP Masters 1000 event as a team this year — where they face Daniil Medvedev and Fabian Marozsan.
Arribage and Olivetti Eye ATP Finals Spot
The French duo have had a stellar 2026 season, winning titles in Halle, Dallas, Auckland, Mallorca, and Montpellier. Currently ranked seventh in the PIF ATP Live Doubles Teams Rankings, they are firmly in contention to qualify for the Nitto ATP Finals, scheduled from 15 to 22 November. A deep run in Montreal would significantly strengthen their case.
What to Watch Next
With Cerundolo and Etcheverry now in the semifinals and the Medvedev-Marozsan pairing still in the mix, the doubles draw at the Canadian Open has taken on an unpredictable shape. Whether the Argentine singles stars can sustain their momentum against more seasoned doubles combinations will be the defining question of the final rounds.
Point of View
However, is the Arribage-Olivetti push for the ATP Finals: five titles in 2026 and a Masters quarterfinal puts them in serious contention, yet they remain under the radar compared to the Heliovaara-Patten juggernaut. Montreal could reshape the doubles narrative for the rest of the season.
