New Delhi, Feb 19: The Indian women's hockey team churned out a much improved performance Sunday to beat Canada 4-1 in their second match of the 2012 London Olympics qualifiers at the Major Dhyan Chand National Stadium here.

After being held 1-1 by low-ranked Ukraine in their opening match, World No.13 India were in the attacking mode right from the start and led 3-0 by the half-time against Canada, who are 20th in the FIH rankings.

Having drawn their opening matches, both India and Canada were in a must-win position to stay alive in the competition. India, however, never looked under pressure and dominated the Canadians with their free-flowing attacking game.

Soundarya Yendala gave India the lead in the 16th minute deflecting in an indirect penalty corner from skipper Asanta Lakra. Three minutes later Rani Rampaul doubled the lead as she dribbled into the D from a free-hit and went past three defenders to sound the board from a base-line hit. 

Sushila Chanu added the third in the 29th minute from an indirect penalty corner while Anduradha Devi Thokchom completed the scoreline in the 49th minute from a field goal. 

Hannah Haughin struck the lone goal for Canada in the last minute from a goal mouth melee. 

The Indian half-line was impressive with Vandana Katariya and Deepika Thakur orchestrating the moves. Yendala Soundarya and Jasjeet Kaur Handa also combined well up-front to keep the Canadian defenders busy.

India's attacking game earned them six penalty corners in the first half as the Canadians looked completely out of sort. In a space of three minutes from 26th to 29th minute, the hosts got four penalty corners and Sushila converted the fourth from an indirect penalty to put India 3-0 up by the break. 

India continued the second-half in the same breadth but the Canadians tightened their defence. India found the net in the 49th minute through an excellent effort from Anuradha, who finished clinically. 

India were unlucky to concede a goal in the last minute. Subadhra Pradhan almost made a goal-line save to thwart Hannah's deflection but the ball struck the diminutive Canadian forward's stick and rolled back into the net.
