Indian colts defeated Australia [ Images ] 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 [ Images ] 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 [ Images ] were the wreckers-in-chief taking three wickets each for India [ Images ].

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 [ Images ] 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.
