Bridgetown, Barbados — Heavy rain associated with Tropical Storm Isaac put a damper on the third round of matches in the West Indies Cricket Board’s Under-19 50-over Tournament on Wednesday.The bad weather started on Tuesday night and continued throughout the day as all three matches ended in a ‘no result’, including the contest at Pine Basin where Bermudian pair Kamau Leverock and Joshua Gilbert are representing the ICC Americas team. The ICC Americas had the upper hand over Leewards Islands, who struggled to 73-6 off 24 overs, in a match reduced to 31 overs per side. Captain Akeem Saunders again propped up his team’s batting with 32 not out off 50 balls before the rain swept across the ground at 3pm.There was also no play between Jamaica and Windward Islands at the Police Sports Complex. The groundstaff worked all morning to get the field ready but a heavy shower at 1.20pm forced the abandonment.At the Desmond Haynes Oval, Guyana were 86-2 off 12 overs against Trinidad and tobago in a match reduced to 28 overs per side because of the wet conditions. Shimron Hetmeyer continued his good form as he blasted three sixes into the pavilion in a hurricane 43 off 26 balls. This knock followed up the run-a-ball 116 he scored in his side’s win over Windward Islands on Monday. Guyana dominated the Trinidad & Tobago attack and were scoring at a rapid rate of over seven runs per over before a heavy shower around 3pm drove the players off the field and left the outfield waterlogged.
