Virender Sehwag smashed the highest score in one-day cricket on Thursday as India flattened the West Indies by 153 runs to take a decisive 3-1 lead in the five-match series. Sehwag hammered a scintillating 219 off 149 balls to lift India to their best one-day total of 418-5, before the West Indies were bowled out for 265 in the fourth international. Debutant leg-spinner Rahul Sharma picked up three wickets in his first three overs as the tourists were outplayed despite a defiant 96 from wicketkeeper Denesh Ramdin. Ramdin put on 64 for the last wicket with Sunil Narine (27 not out) before he was caught in the deep attempting to score his maiden one-day century.Sehwag plundered 25 boundaries and seven sixes during his 149-ball blitz, joining Tendulkar as the only batsmen to score double-centuries in ODIs.
