Shelton Demolishes Mensik – Ten Straight Wins in Canada
Ben Shelton produced the most dominant performance of the entire 2026 Canadian Open on Tuesday, dismantling 13th seed Jakub Mensik 6-3, 6-1 in just 73 minutes to advance to his 16th career ATP Tour semifinal and extend his winning streak in Canada to ten consecutive matches.
The result silenced any concern about the head-to-head record that had given Mensik a psychological advantage heading into the match. Mensik had beaten Shelton twice in 2026 on hard courts, but on Tuesday there was no hint of that history in the performance the defending champion delivered. He was simply too powerful, too composed, and too accurate for an opponent who finished the match with 16 unforced errors to Shelton’s three.
Shelton has now won four consecutive matches in straight sets at the 2026 Canadian Open without dropping a single set across the entire tournament. His serve, his forehand, and his left-handed angles have been at their most clinical all week, and Tuesday’s quarterfinal was the clearest expression yet of why he arrived in Montreal as the defending champion and favourite.
Shelton vs Mensik match breakdown:
| Stat | Shelton | Mensik |
| Score | 6-3, 6-1 | Lost |
| Duration | 73 minutes | 73 minutes |
| Unforced errors | 3 | 16 |
| Sets dropped tournament | 0 | N/A |
| Canada winning streak | 10 consecutive wins | N/A |
| Career SFs | 16th | N/A |
Shelton after the match:
“It felt great.”
Three words that captured the confidence of a defending champion who has found his best tennis at the most important moment of his title defence. His next opponent is Learner Tien, who leads their head-to-head 2-0 and beat Shelton at Indian Wells earlier this year.
Jodar Stuns Fils – 19-Year-Old Makes History
Rafael Jodar produced the most significant result of his young career on Tuesday, defeating 18th seed Arthur Fils 7-6(5), 6-3 to reach his first ATP Masters 1000 semifinal and confirm one of the most remarkable debut seasons any player has produced on the ATP Tour in recent memory.
The 19-year-old Spaniard arrived in Montreal ranked world No. 168 at the start of 2026. After Tuesday’s victory over Fils he sits at world No. 11 in the live ATP rankings, a rise of more than 150 places in a single season that reflects a player whose development has accelerated beyond anything his pre-season ranking suggested was possible.
His 2026 season record now stands at 34-13, built on a first ATP Tour title in Marrakech and a series of breakthrough results at the biggest events on the calendar. The victory over Fils in Montreal, a player who had also enjoyed a strong 2026 season and lifted a title in Barcelona, was his most significant scalp yet in what has already become one of the most decorated debut seasons in recent ATP history.
Jodar vs Fils match breakdown:
| Set | Score | Key Moment |
| First set | Jodar wins 7-6(5) | Tiebreak decides tight opener |
| Second set | Jodar wins 6-3 | Controlled performance, broke twice |
| 2026 season record | 34-13 | First year on ATP Tour |
| Ranking rise | No. 168 to No. 11 live | Most dramatic debut rise in years |
| First Masters 1000 SF | Confirmed | Historic milestone |
Jodar after the match:
“My goal is still the same, to improve and discover all the tournaments in my first year on the tour.”
That quote captures the mindset of a 19-year-old who has not allowed his extraordinary results to change his approach or his ambition. He faces Brandon Nakashima in the semifinals on Wednesday, a first ever meeting between two players who have both produced breakthrough results at the 2026 Canadian Open.
Nakashima Reaches SF – 150th Win and Career High
Brandon Nakashima delivered one of the most statistically significant performances of his career on Tuesday, defeating 19th seed Luciano Darderi 6-2, 6-3 to record his 150th career tour-level victory, reach his first Masters 1000 semifinal, and climb to a career high ranking of world No. 25 in the live ATP rankings.
The victory was built on the twin weapons that have defined Nakashima’s entire Canadian Open campaign. His serve generated 11 aces against Darderi and his forehand consistently put pressure on the Italian’s baseline game throughout both sets. Darderi, a five-time ATP Tour champion whose titles have all come on clay, found the pace and consistency of Nakashima’s hard court game too much to handle across 70 minutes of play.
The match told a simple story. Nakashima converted a break point in the fourth game of the first set before breaking Darderi to love to close out the opener. The Italian dug in during the second set and pushed Nakashima in his service games, but the American remained composed and broke Darderi on his fourth attempt in the penultimate game to seal his place in the semifinals.
Nakashima vs Darderi match breakdown:
| Stat | Detail |
| Score | 6-2, 6-3 |
| Aces | 11 Nakashima aces |
| 150th career win | Confirmed milestone |
| Career high ranking | World No. 25 live |
| Hard court record since Wimbledon | Seven of eight wins |
| First Masters 1000 SF | After 36 attempts to reach QF |
Nakashima after the match:
“My serve and my forehand have been really in form the last couple of weeks.”
That straightforward assessment reflects a player who has found the consistency on his two biggest weapons that makes him dangerous against any opponent on hard courts. He next faces Rafael Jodar in the semifinals on Wednesday at 6PM ET, a first ever meeting between the two players that sets up as one of the most intriguing clashes of the entire tournament.
Tien Ends Merida Fairytale – First Masters 1000 Semifinal
Learner Tien ended Daniel Merida’s extraordinary Montreal story in emphatic fashion on Tuesday, defeating the Spanish qualifier 6-3, 6-2 in just over one hour to reach his first Masters 1000 semifinal and confirm his place as one of the most dangerous players remaining in the Canadian Open draw.
Merida had been the feel-good story of the entire Montreal draw, arriving without a single tour-level hard court victory before the tournament and reaching the quarterfinals with five consecutive wins that included the elimination of Tallon Griekspoor, the man who had stunned top seed Zverev on Day 5. His run captured the imagination of tennis fans worldwide and reflected the wide-open nature of a draw that had lost all of its top four seeds before the quarterfinals.
But Tien’s left-handed game, superior hard court record, and Masters 1000 experience proved too much for a player whose remarkable run had finally met its limit on Tuesday afternoon.
How the match unfolded:
Merida broke Tien’s serve in the opening game, the same aggressive start that had defined his approach against every opponent this week. But Tien responded immediately, breaking back in the fourth game and reeling off the next four games to establish a commanding advantage that he never surrendered.
Match breakdown:
| Moment | Score | Detail |
| Merida breaks first game | 1-0 | Aggressive start, same pattern as all week |
| Tien breaks back | 2-1 | Fourth game, responds immediately |
| Tien runs away | First set won 6-3 | Wins next four games after break back |
| Second set | Tien wins 6-2 | Never in doubt, first Masters 1000 SF confirmed |
| Match duration | Just over one hour | Dominant Tien performance |
Tien next faces defending champion Ben Shelton in an all-American semifinal on Wednesday night, entering the match with a 2-0 head-to-head advantage over Shelton including a victory at Indian Wells earlier this season.
The All-American Semifinal – Shelton vs Tien
The most anticipated match of Wednesday’s semifinal day at the 2026 Canadian Open is the all-American clash between defending champion Ben Shelton and 12th seed Learner Tien, a matchup that carries the weight of a head-to-head record, a title defence, and the most compelling American men’s tennis rivalry of the 2026 season.
Tien leads their career head-to-head 2-0, with both victories coming on hard courts in 2026. His most recent win over Shelton came at Indian Wells earlier this year in the second round, where his left-handed return game and baseline consistency proved decisive against the defending champion’s powerful serve.
Shelton vs Tien head-to-head:
| Meeting | Tournament | Winner | Surface |
| 2026 meeting 1 | Indian Wells | Tien | Hard |
| 2026 meeting 2 | Indian Wells R2 | Tien | Hard |
| Career H2H | Tien leads 2-0 | All hard courts |
The contrasting paths to the semifinal:
Shelton has not dropped a single set across four matches in Montreal, dismantling Fonseca, Bergs, and Mensik with the kind of serving dominance that makes him the most dangerous player in the draw when his first serve is working at this level. Tien has been equally efficient, defeating Monfils, Paul, Tirante, and Merida without facing a genuine crisis at any point of his campaign.
The key tactical question:
Tien’s 2-0 head-to-head advantage reflects a left-handed player whose return game creates consistent difficulties for Shelton’s left-handed serve, removing the angle advantage that makes Shelton’s delivery so effective against right-handed opponents. When two left-handers meet, the tactical dynamics shift completely, and Tien has shown twice in 2026 that he understands how to navigate that specific matchup better than Shelton currently does.

Canadian Doubles Exit – Chan and Galarneau
The last remaining Canadian presence at the 2026 National Bank Open was eliminated on Tuesday when Duncan Chan and Alexis Galarneau lost their men’s doubles quarterfinal to Francisco Cerundolo and Tomas Martin Etcheverry, ending the all-Canadian doubles partnership that had been one of the most celebrated stories of the Montreal draw.
Chan and Galarneau had delivered genuine cause for celebration across the first week of the tournament, defeating the Zverev and Melo pairing in the first round before eliminating eighth seeds Pierre-Hugues Herbert and Kevin Krawietz in the second round. Their run gave Montreal fans a Canadian story to follow through the second week after all Canadian men had exited the singles draw through injury or defeat.
Chan and Galarneau doubles run:
| Round | Opponents | Result |
| Round 1 | Zverev / Melo | Won |
| Round 2 | Herbert / Krawietz (8) | Won |
| Quarterfinal | Cerundolo / Etcheverry | Lost |
The Argentine pairing of Cerundolo and Etcheverry, who had upset top seeds Heliovaara and Patten in the same quarterfinal session, proved too strong for the Canadian wildcards in what was ultimately a match too far for a partnership that had significantly outperformed expectations throughout the tournament.
With Chan and Galarneau eliminated, no Canadian player or team remains in any draw at the 2026 Canadian Open. The tournament will be decided entirely by international players across both the men’s singles in Montreal and the women’s singles in Toronto, leaving Canadian fans to follow the remaining action without a home representative in any competition for the first time since the opening week.

Conclusion
The Canadian Open 2026 ATP quarterfinals results delivered everything the tournament had been promising since the draw was released before August 1.

Wednesday brings Nakashima vs Jodar at 6PM ET and Shelton vs Tien under the lights on Centre Court at IGA Stadium. One match will deliver a first-time Masters 1000 finalist.
