Defending champions India quelled a late Korean surge to eke out a narrow 3-2 victory and stretch their unbeaten run in the Sultan Azlan Shah Cup hockey tournament at Ipoh Malaysia today. The Indian scorers were Arjun Halappa (10th minute), Tushar Khandker (45th) and Shivendra Singh (60th), while Korea scored through two penalty corner strikes by Nam Hyun Woo in the 12th and 70th minutes. India began aggressively mounting onslaughts with central midfielders Arjun Halappa and Vikas Pillay setting up wingers Mandip Antil and Tushar Khandker who penetrated and split the Korean defence. India were awarded a series of opportunities in the form of seven penalty corners but the defending champions failed to convert any of them. Dhananjay Mahadik not only lacked the power for the set pieces but was also devoid of imagination for indirect variations.
