Jamaica: A 155-run stand between Shamarh Brooks and Keiron Pollard helped the West Indies to a 24-run victory over Ireland at Sabina Park on Saturday.
The hosts were struggling on 62-4 before Brooks (93) and skipper Pollard (69) put on a decisive partnership.
West Indies were dismissed for 269 and Ireland were well set on 165-1 before the fall of Andrew Balbirnie (71) triggered a collapse.
Romario Shepherd took 3-50 as the tourists were bowled out for 245.
Ireland were already missing key batsman Paul Stirling and Shane Getkate because of Covid-19 before Simi Singh and Ben White were ruled out on Saturday morning after testing positive - the pair are awaiting results of PCR tests.
The Irish elected to field in the World Cup Super League game and it looked like a good decision before Brooks and Pollard brought the Windies to 217-4.The final six wickets fell relatively cheaply and the Irish were very much still in the game.
Mark Adair (3-38) and Craig Young (3-56) were the best of the Irish attack and they gave their side a decent chance of repeating the famous victory over the West Indies at the 2015 World Cup.
William Porterfield fell for a duck before Andy McBrine (39) retired hurt after being hit on the helmet with the score on 62-1, but it was only a temporary setback as Harry Tector (53) impressed at number four.
Balbirne and Tector flourished as they added 103 runs but Ireland slumped from 165-1 to 194-6 to put the hosts in control. Mark Adair smashed an unbeaten 21 from just nine balls but Ireland finished 24 runs shy with five balls remaining.
The teams meet again in the second ODI on Tuesday with the final match of the Sabina Park series three days later.
