West Indies all-rounder Matthew Forde equalled AB de Villiers's record for the fastest one-day international half-century before Friday's match against Ireland in Dublin was abandoned due to rain.
Forde reached 50 in just 16 deliveries –- matching the mark set by South Africa's De Villiers, one of the outstanding limited-overs batsmen of his generation, in 2015.
In all, Forde struck eight sixes and two fours in a 19-ball 58 as West Indies piled up an imposing 352-8 in their 50 overs.
Keacy Carty had earlier hit 13 fours and a six during a less spectacular 102 off 109 deliveries.
Liam McCarthy led Ireland's attack with 3-66, while Barry McCarthy and Josh Little took two wickets each.
But the match was abandoned without Ireland even starting their reply following a two-hour rain delay.
Ireland lead the three-match series 1-0 after their 124-run win on Wednesday, with the two sides set to meet again in the finale on Sunday.
Brief score:
West Indies 352-8, 50 overs (K. Carty 102, M Forde 58; L McCarthy 3-66) v Ireland
