The win made it four consecutive straight-sets victories for the 23-year-old American at this year's edition of the tournament.
Shelton's Dominant Display
Shelton was near-flawless in the quarterfinal, unleashing 18 winners against just three unforced errors and winning 89 percent of first-serve points. He did not face a single break point throughout the match and fired a blistering 147 mph serve to underline his authority on court.
'It felt great,' Shelton said after the match. 'I was very happy with my return game. The way that I played from the ground, from point one, for me, that's where I want to be at. I think the level I maintained throughout the match was really high. I'm super happy with my performance. Hope to continue to build on this in the semis.'
An All-American Semifinal Showdown
Shelton, the only Top-10 player left in the draw, will face 12th-seeded compatriot Learner Tien in the last four. Notably, Tien leads their head-to-head rivalry 2-0, with his most recent win coming in the second round at Indian Wells earlier this year — a result that adds an intriguing subplot to the upcoming clash.
Tien's Milestone Semifinal
The 20-year-old Tien booked his place in the semis with a 6-3, 6-2 dismantling of Daniel Merida in just one hour and 12 minutes, reaching his first-ever Masters 1000 semifinal. The result caps a rapid rise for Tien, who has also reached his first Grand Slam quarterfinal at the Australian Open, his first Masters quarterfinal at Indian Wells, and claimed his first clay-court title in Geneva — all within the same season.
Tien was measured in his assessment of the challenge ahead. 'No matter how Ben is feeling, he is going to serve well,' Tien said. 'He is going to hit a big ball off the baseline. He is playing with a lot of confidence right now. I saw him play earlier today. He is playing very, very well.'
What's Next
The all-American semifinal sets up one of the more compelling matchups of the 2025 Montreal Masters season. Shelton will look to leverage his serving firepower and defending-champion momentum, while Tien will draw confidence from his unbeaten record against his compatriot. The winner advances to the final, where a title defence or a maiden Masters crown awaits.
Point of View
Yet he enters as the man with the losing head-to-head record against a 20-year-old who has been collecting 'firsts' all year — first Slam quarterfinal, first Masters quarterfinal, first clay title, now first Masters semifinal. Tien's rapid accumulation of milestones in a single season is the more significant trend here. If he beats Shelton again, the conversation shifts from 'promising youngster' to genuine top-tier contender well ahead of schedule.
