An exemplary display by the defenders and gallant goalkeeping by Sreejesh helped India cruise into the semifinals, defeating defending champion South Korea 2-0 in the Asia Cup hockey championship here on Monday. The Indians scored once in each half. Imagine a show with Korea unable to score off five penalty corners, all in the first half. Nothing disturbed the composure of Sreejesh, whose athleticism and alacrity under the bar stood pronounced. Even a cascade of sallies by the Koreans could not upset the rhythm and coordination of the defensive phalanx where Sardar Singh was conspicuous as ever.
