Indian colts defeated Australia Under-19 side by 31 runs in the fifth and final one-day match to clinch the series 4-1 at the Ferozeshah Kotla ground in New Delhi on Wednesday.

Electing to bat, the Indians were dismissed for a paltry 196 in 45.4 overs but came back strongly to wrap up the tourists for 165 in 38.1 overs underlining their domination in the series.

Leg-spinner Piyush Chawla [Images] and left-arm tweaker Pragyan Ojha were the wreckers-in-chief taking three wickets each for India.

They used their guile, variations and change of pace to good effect keeping the youngsters from Down Under at bay after they started on a brisk note. Losing wickets at regular intervals they were 66 for four after 10 overs.

The Uttar Pradesh leg-spinner was especially impressive as he displayed his full repertoire of skills - the leg-break, googly and flipper - to keep the batsmen at tenterhooks.

Ojha got disconcerting bounce and turn from the wicket which was uneven and slower than the ones the teams encountered at Mohali and Dharamshala [Images].

A 64-run partnership for the fifth wicket between Tom Cooper (45; 5x4, 1x6) and David Warner (73; 5x4, 3x6) appeared to put the Aussies firmly on the victory path but the former was caught at deep midwicket going for a big hit with the team total on 119.
