Shelton and Merida power into Montreal quarter-finals as hardcourt specialists emerge

Ben Shelton maintained his flawless record in Canada, reaching the Montreal quarter-finals without dropping a set after a gritty 6-4, 7-6 victory over Brazilian teenager João Fonseca. The 23-year-old American left-hander, currently ranked 10th in the world, will face 13th seed Jakub Mensik of the Czech Republic for a place in the semi-finals.

Mensik earned his spot with a dramatic 6-4, 7-5 win over Botic van de Zandschulp, seizing control after the Dutchman served for the second set. The Czech won 12 of the final 14 points, finishing the match with a winning lob that capped a remarkable comeback.

Fonseca's chance slips away

The match against Fonseca swung on fine margins. The 18-year-old Brazilian, widely tipped as a future star, led in both sets and held a 3-1, 40-30 advantage in the second before landing awkwardly on his ankle after missing a smash. He finished with 32 unforced errors as swirling winds disrupted rhythm for both players.

It was tough today, not easy conditions. With the wind I struggled to find footing on a lot of balls. It all came down to grit. The tennis was not clean. Beating a high-quality player like that is huge for me.

Shelton converted on his fourth match point when Fonseca netted a return, extending the American's Canadian winning streak to nine matches across two seasons.

Merida's hardcourt awakening

While Shelton's progress fits a familiar narrative, Daniel Merida is writing a new one. The 22-year-old Spaniard, ranked 63rd, had never won a tour-level match on hardcourt before arriving in Montreal. Four victories later, he is into the quarter-finals and guaranteed a career-high ranking inside the top 50.

Merida dismantled Dutchman Tallon Griekspoor 6-3, 6-1 in just 69 minutes, his backhand repeatedly wrong-footing the 28th-ranked player. The win follows his clay-court title in Umag last month and brings his season tally to 16 victories.

This is a dream come true. I'm feeling really great. I'm happy with the level during all the week. I was playing great for the last year and the beginning of this year so I just starting to believe more in myself.

Merida joins compatriot Rafael Jodar in the last eight, marking the first time since 2019 that two Spanish men have reached the quarter-finals of a Masters 1000 event on hardcourt.

Tien survives break-point barrage

Merida's next opponent, American Learner Tien, advanced with a 6-4, 6-4 win over Argentina's Thiago Tirante. The 12th seed faced eight break points in the second set alone, saving all of them before closing out the match on his fifth match point after Tirante coughed up four unforced errors in the final game.

Today was humid, conditions are always tough. I'm happy with how the match worked out. This was one of those days where I was making good contact with the ball. I was seeing the ball well and returning well.

The quarter-finals begin Thursday, with Shelton targeting a first Masters 1000 semi-final since Shanghai 2023 and Merida chasing a result that would have seemed improbable a fortnight ago.
