Sri Lanka ran into the rampant pair of Shivnarine Chanderpaul and Marlon Samuels, and lost the rain-marred second One-Day International against West Indies by seven wickets under the Duckworth-Lewis Method on Saturday. Chanderpaul smote three fours and two sixes in an unbeaten 52 from 42 balls, and Samuels struck three fours and three sixes in 54 not out from 49 balls, as West Indies, chasing 125 for victory from 25 overs, hit the jackpot with 27 balls to spare. The result was formalized, when Chanderpaul, named man of the match, tucked a delivery from Tillakeratne Dilshan into mid-wicket for a single to spark tumultuous celebrations. The victory gave West Indies an unbeatable 2-0 lead in the three-match series, after it won the opening ODI by one wicket on Thursday at the same venue. The third and final ODI in the series will be contested on Tuesday at the Beausejour Stadium in St. Lucia. Sri Lanka had earlier reached 112 for five from 30.3 overs, but persistent unseasonal rain disrupted its innings twice - the last of which cut short their innings - and caused a 3-1/4-hour delay which condemned West Indies to its final target. Upul Tharanga's 40 from 82 balls was the best effort from the Sri Lankans with the bat, and Kumar Sangakkara made 28. West Indies captain Chris Gayle was his side's most successful bowler with two wickets for six runs from 1.3 overs.
