Portchefstroom: Pacer Kartik Tyagi blew away the Australian top-order with a sensational spell to power India into the semifinals of the ICC U-19 World Cup with a comfortable 74-run win here on Tuesday. Kartik's four wickets came after India recovered through Atharva Ankolekar's combative half-century to reach 233 for nine, a modest total which the holders defended in impressive fashion.

Riding on Kartik's spell in which he swung the ball at a good speed, India bundled out Australia for 159 with 6.3 overs to spare in their Super League quarterfinal. Invited to bat, India lacked a substantial partnership until Atharva and Ravi Bishnoi joined forces to raise a fighting 61-run stand for the seventh wicket. Atharva scored an unbeaten 55 off 54 balls with five fours and a six, while Bishnoi made 30 off 341 balls. Tyagi (4/24) then produced a dream spell in which he removed Australian skipper Mackenzie Harvey (4) and Lachlan Hearne (0) in successive balls in his very first over.
