Earlier, Tamil Nadu swamped Bihar 7-2 with forward Prabhakaran accounting for four goals in Group D and Indian Railways scored a 2-0 win over CRPF in Group A.

The bankmen, tied on five points with Bombay after today's draw, required just eight minutes to go into the lead through their first penalty corner.

Harpreet Singh Channi shot came off the stick of Saurab Bishnoi from the goal mouth and centre-forward Parminder Singh shot home.

After that, Bombay spearheaded by India captain Dhanraj Pillay dominated play almost through to the break. During this period, they squandered eight penalty corners and at least on five occasions it was PSB's Sandeep Singh Ghuman, who cut in superbly to deflect the shots, thereby helping his team hang onto the lead.

Crossing over, Bombay scored following their tenth penalty corner (39th minute) -- Sandeep Somesh sounding the boards directly. The game rose in excitement with both the teams, mostly Bombay, going all out for the winner.

However, neither team could gain on their forays.

Bombay forced two more penalty corners during the last three minutes but the bankmen's citadel held firm.

Earlier, Tamil Nadu dominated proceedings against Bihar. Prominent players like Paul Kirubhakaran, D Felix and L Prabhakaran, exhibited their skills in great measure, being fed regularly by Dinesh Nayak and Thirumalvalavan.

At half-time Tamil Nadu led 2-1 through Dinesh Nayak and Felix while Bihar's Guria managed to pull one back for his team.

For Tamil Nadu, Prabhakaran scored four excellent field goals, dodging a host of defenders including the goalkeeper each time.

Captain Paul Kirubhakaran, who was outstanding, be it offence or defence, netted the fifth goal.
