The Montreal Masters witnessed another seismic shift on Thursday as Cameron Norrie erased a match point deficit to topple third seed Alex de Minaur 5-7, 7-6(7/5), 6-1, extending the tournament's pattern of stunning upsets. The British left-hander, who once claimed the Indian Wells title, dug deep after trailing by a set and a double break, ultimately converting his own match point 62 minutes after his opponent squandered his chance. Main Developments Norrie's victory unfolded in dramatic fashion, with de Minaur seizing a 4-1 first-set lead and winning six of seven games to claim the opener. The Australian, who had been the highest remaining seed in a depleted draw, held a match point opportunity in the eighth game of the second set but failed to convert, allowing Norrie to level via a tiebreaker. The third set became a rout as Norrie raced to a 6-1 win, capitalizing on de Minaur's sudden dip in form. "I was in a good position," de Minaur admitted. "It's tennis. As we've seen, anything can happen. I gave myself chances early in the third set, and then I just played some bad points in a row and then got behind. It all just went very quickly."

"I can take so much confidence from this one. The level was so high in the first set. He came out firing and I had to match it. Alex stayed tough and stole the first set but took his foot off the gas just slightly in the second." Elsewhere, Jiri Lehecka, the eighth seed, advanced with a 6-3, 6-4 win over Belgium's Alexander Blockx and will face Spanish teen Rafael Jodar, who upset 13th seed Lorenzo Musetti. Meanwhile, Arthur Fils, the 24th-ranked Frenchman, beat Mariano Navone 6-3, 6-2, setting up a fourth-round clash with Norrie. Women's Draw Highlights In Toronto, top-ranked Aryna Sabalenka advanced to the fourth round by defeating China's Zhang Shuai 6-3, 6-4, dropping just seven points on her first serve in 76 minutes. The 28-year-old Belarusian, a four-time Grand Slam champion, struggled early but found her rhythm, saying, "I was trying to step in and then I would step back and nothing really clicked. In the end I finally started moving a little bit better and finding my rhythm." Sabalenka, who holds a 38-6 record this year with three titles, next faces Russian 16th seed Ekaterina Alexandrova, who overcame Talia Gibson 5-7, 6-1, 6-3. The pair split their nine prior meetings, with Sabalenka winning on Berlin grass this year but Alexandrova taking their last hardcourt clash at Doha in a third-set tiebreaker. American third seed Jessica Pegula cruised past Kamilla Rakhimova 6-4, 6-0 in 68 minutes, setting up a meeting with Diana Shnaider, who beat compatriot Anna Kalinskaya. Polish seventh seed Iga Swiatek also advanced, dismantling Viktorija Golubic 6-2, 6-1 in 66 minutes, and will face 10th seed Marta Kostyuk, who dispatched Madison Keys. Background This year's Montreal Masters has been defined by a wave of high-profile withdrawals and early exits, leaving the draw wide open. Top seed Alexander Zverev was eliminated early, while Canadian second seed Felix Auger-Aliassime pulled out due to injury, and fourth seed Daniil Medvedev suffered a loss. World number one Jannik Sinner and 24-time Grand Slam champion Novak Djokovic were absent entirely. Norrie's victory continues his resurgence after a challenging period; he had not reached a final since his Indian Wells triumph in 2021. De Minaur, meanwhile, was a losing finalist in Canada three years ago, falling to Sinner, and had been expected to capitalize on the depleted field. The women's event has seen steadier progress, with Sabalenka, Pegula, and Swiatek all advancing without major scares. Sabalenka, who has spent over 100 weeks atop the rankings, relishes her position, saying, "I enjoy being the one being chased. It's really fun. It's tough challenges but I love to go through it and it makes me stronger." Why It Matters The Montreal Masters is a key US Open tuneup, and the chaos in the men's draw has reshaped the title race. With no top-five players remaining, fifth-seeded holder Ben Shelton emerges as the new favorite, but Norrie's win signals that the trophy could go to any of the survivors. For Norrie, the victory provides a confidence boost ahead of the final Grand Slam of the year, while de Minaur's early exit raises questions about his form on hardcourts. For the women, Sabalenka's dominance and Swiatek's steady progress set up a potential blockbuster clash in the latter rounds, with implications for the world number one ranking. Pegula, a consistent performer, also remains a threat, and the tournament is building toward a compelling finish. What's Next Norrie will face Arthur Fils in the fourth round, a player who has battled back from a long injury layoff and expressed joy at "being back on the big stage." Fils, who
