Haitian international striker Kervens Belfort scored the all important winner in the 64th minute to keep Kerala at the driver's seat in the two-legged semi-final clash.
Midfielder Mehtab Hossain made a comeback into the side after serving one-match ban due to bookings. The former India international was as usual in a no-nonsense mood as he pulled out a rough tackle on Florent Malouda in the opening moments of the match.
Blasters travel to Delhi now to play the second leg. They will be in an advantageous position but there is no complacency considering how good Dynamos are at their home.
