KATHMANDU: India's opening batsman Manjot Karla struck an unbeaten blistering ton to thrash Australia by 8-wicket and propelled his team to clinch the record 4th U19 Cricket World Cup title.

After winning the toss, Aussie skipper Jaskirat Singh Sangha opted to bat first in the title decider game, played at the Bay Oval, Mount Maunganui, in New Zealand, on Saturday.

Australia, who were earlier beaten by 100 runs by India in group game, managed to muster a paltry total of 216 before being bowled out in 47.2 overs in their allotted 50 overs.

All up, India required only 85.7 overs to wrap up the match and lift the coveted trophy, folded Aussie for below par score of 216 in 38.5 overs and needed only 38.5 overs to overcome the target set by the opposition.

Kalra remained not out on 101 off just 102 balls, studded with three humongous sixes and eight fours, including scorching off drives on the up.

Jonathan Adam Merlo top scored with 76 runs off 106 balls, which included six fours. Param Uppal contributed 34 runs. Indian bowlers took wickets at regular interval which dented Australia's hope of posting a challenging total on a batting wicket.

Anukul Roy, Ishan Porel, Shiva Singh, Kamlesh Nagarkoti took two wickets each while spearhead Shivam Mavi bagged a wicket.

It was a tough ask for the Aussie bowlers to defend a decent total against a formidable Indian batting line-up. Aussie bowlers had to toil hard to pick India wickets as Indian batsmen chased down the target with ease.

India made a solid start as they lost their first wicket for 71 runs. Skipper Prithvi Shaw trudged off after scoring 29 runs off 41 balls with four hit to the fence. Shaw was undone by the delivery which nipped back after pitching to breach his defence to peg back his timbers.

India were never put on any pressure on the run chase as they were way ahead with the run rate.

Kalra and Shubman Gill then shared 60 runs partnership for the second wicket. Gill, in-form batsmen of the tournament departed after scoring 31 runs in 43 balls with four fours.

Uppal served a pitch-of-a-delivery which turned sharply to crash into the stumps after Gill failed to read the ball.

By the time India required another 85 runs with eight wickets in hand and more than 28.8 overs remaining.

Harvik Desai and Kalra shared another 89 run partnership for the third wicket in which Desai contributed 47 runs including five fours in 61 delivery.

Australia bowlers did not have much to cherish as Param Uppal and Will Sutherland took a wicket each.

Manjot Karla was adjudged as man of the match for his match winning innings and Shubman Gill bagged the player of the series award.
