Punjab Police, led by forward Gagan Ajit Singh, grabbed the initiative from the outset with their forwards not only keeping the Indian Oil custodian Devesh Chauhan busy but also earning two penalty-corners.

But it was Indian Oil who nearly scored in the 24th minute through a penalty-corner. However, DeepakThakur's goal was disallowed by referee H S Sodhi since his hit went into the into the net instead of sounding the board.

Aiyappa, who had converted all three penalty-corners in his team's last league match, made no mistake with the chance he received in the eighth minute of extra-time to take his team into the last four.

Bharat Petroleum, who went into the breather with a 1-2 deficit, went for the kill in the second half and were in the driver's seat by the 54th minute, leading the tie 4-2. But the bankmen were not ready to surrender and restored parity to force the tie into extra-time.
