Mumbai, May 29 : Jamal Sakib of Services, seeded 5/8, scored a minor upset over fellow player from Services Vaibhav Chauhan (3/4) to enter the men's singles semifinals of the 6th NSCI Open National Circuit squash tournament here, on Monday. With both players familiar with each other's playing styles, fortunes changed hands with each game but a visibly tired Chauhan could not put up much of a fight in the decider, going down tamely in the event hosted by NSCI at their glass-backed squash courts, Sakib prevailed 11-9, 8-11, 11-5, 3-11, 11-5 to set up a last-four clash with second seed Suraj Chand of Delhi, who got the better of TN's Vikas Mehra (58) 13-11, 11-1, 7-11, 6-1 (Retd).
