In an authoritative show, Indian colts trounced Australia by a massive 100-run margin in their ICC Under-19 World Cup opener with bowlers complementing a splendid batting performance, here. Skipper Prithvi Shaw led from the front with a 94-run knock and shared a 180-run stand with fellow opener Manjot Kalra (86) to power India to a challenging 328 for seven. There was no respite for the Australians even after their departure with Shubman Gill tormenting the bowlers with his 63-run knock.
