St Mary's SSC (Mazagaon) knocked out defending champions Don Bosco 'A' (Matunga) 5-2 via tie-breaker to enter the boys U-16 Division I semi-finals of the Mumbai Schools Sports Association (MSSA) after 12 years, in a keenly contested encounter at Azad Maidan yesterday.

Despite some decent crowd support and cheers from the sidelines, the Bosco boys seemed to be struggling against the Mazagaon side. In the 15th minute, Don Bosco coach Leslie Machado brought in striker Shyam Redekar in place of Keith Fernandes. And just when the Bosco boys seemed to be settling in, St Mary's broke the deadlock in the 21st minute.
