Former Olympic champion Argentina was made to struggle by world No.14 South Africa before the former registered a 1-0 triumph in the opening Group A game of the 2023 FIH Men's Hockey World Cup at the Kalinga Stadium in Bhubaneshwar on Friday. After an exhausted and closely-contested opening couple of quarters, Argentina, the 2016 Olympic gold medalist, slashed the winner in the 42nd minute via a field measure from Casella Maico. However, it was far from blushing for Los Leones as South Africa pressed hard in the opening quarter, failing to transform its opportunities into favourable outcomes. In the next quarter, Argentina returned forcefully and assured three penalty corners before wasting all of them, as South Africa guarded stoutly.
