An upset at the Pakistan Navy Fleet Club Open International Squash Championship has reshaped the semi-final lineup, with world No. 78 Asim Khan ousting top seed and compatriot Noor Zaman in a quarter-final that ended in injury. The match, played Sunday at the Pakistan Navy Roshan Khan-Jahangir Khan Squash Complex in Karachi, saw Asim recover from a first-game loss to force a retirement from Noor. Main Developments After dropping the opening game 9-11, Asim took the next three games 11-9, 11-1, and 11-3 before Noor retired due to injury near the end of the fourth. The victory marked a significant turnaround for Asim, who admitted his recent performances had been below expectations. “I am feeling great, it was a tough match,” Asim said. “My performances weren’t up to the mark for the past couple of years so it feels good to win against my team-mate and top-seed.” He credited a tactical shift after the first game, focusing on reading Noor’s game and then executing a plan to keep him in the corners.

Nasir admitted Hamza’s comeback made it difficult to halt momentum, but he managed to execute his plan in the decider. Nasir will face Egypt’s Yassin Elshafei, who defeated Ali Tolba 3-2, while Asim will meet Salman Khalil, who beat Mohamed Naseer 3-0. The semi-finals are scheduled for Monday, with the final on Tuesday. Background The tournament is a key stop on the international squash circuit, with a prize purse of $41,000. Asim’s world ranking of 78 places him well below Noor, who entered as the top seed and a team-mate in Pakistan’s national squad. The event is held at the Pakistan Navy Roshan Khan-Jahangir Khan Squash Complex, a venue named after two of Pakistan’s squash legends. Why It Matters Asim’s upset signals a potential shift in Pakistan’s squash hierarchy, where younger players like Noor have been seen as the future. For Asim, the win could reignite a career that has struggled in recent years. Nasir’s progress, meanwhile, shows that experience still counts in a sport increasingly dominated by younger talent. What's Next Both semi-finals are set for Monday. Asim will look to maintain his newfound form against Salman, while Nasir faces a tough test against Elshafei. The final on Tuesday will decide who takes home the $41,000 prize purse.
