Left-arm spinner Shahbaz Nadeem was the architect of India Under-19's thrashing of England [Images] by a huge margin of 250 runs in the third and final Test at the Denis Compton Oval, Shenley.

The victory enabled the Indians win the series 1-0.

Sixteen-year-old Nadeem from Bokaro claimed five for 41 as England, set an improbable target of 447, were wrapped up early for 197 in 105.5 overs on Wednesday.

A defiant half-century by Michael O'Shea kept England's hopes of snatching a draw alive as the hosts had managed to avoid defeats in the first two drawn matches.

But it was not to be this time around as their innings came to an end soon after the dismissal of the 18-year-old right-handed Glamorgan bat.

O'Shea, who struck a valuable 39 in the first knock, top-scored with 56 and kept the Indians at bay as he extended the hosts' total from 159 for eight to 197.

Leg-spinner Karan Singh (3-26) from Chandigarh delivered the killer punch by having O'Shea caught by a substitute and then the number 11 Steven Finn for a duck in the space of three balls.

Earlier, Punjab teenager Sumit Sharma fell one short of a century to set up the stage for Indian colts' victory on the third day on Tuesday.

Sharma was unlucky to be dismissed on 99 but his stellar knock helped his team declared their second innings at 293 for seven in 75.3 over. The Amritsar-born batsman cracked 10 fours and two sixes, facing 142 balls, during his three hour-plus stay at the crease.

The Indian colts had clean swept the three match one-day series at the beginning of the tour.
