St Lucia, Aug 14 (IANS): India defeated West Indies by 237 runs in the third Test at the Darren Sammy National Cricket Stadium here on Saturday to take an unassailable 2-0 lead in the four-match series.

Set a victory target of 346 runs, the West Indies were bundled out for a mere 108 runs in the second innings on the fifth and final day.

India had won the first Test by an innings and 92 runs at Antigua on July 24, while the second Test at Kingston in Jamaica ended in a draw on August 4.

Bravo's 100-ball stay in the middle was studded with one six and five boundaries.

Shami was the most successful among the Indian bowlers with figures of 3/15. Fellow fast bowler Ishant (2/30) and left-arm spinner Ravindra Jadeja (2/20) also bowled well.

Earlier on Saturday, the Indians had declared their second innings at 217/7.
