AB de Villiers served up an ominous warning for Ireland with a spectacular, record-breaking display against the West Indies this morning.

The South African batsman hit the fastest 150 in one-day international cricket history as his Proteas thrashed the Windies by 257 runs at the World Cup.

De Villiers took just 64 balls to get to 150, and finished on 162no as South Africa posted a huge 408-5 from 50 overs.

The Windies were bowled out for 151.

Ireland face South Africa in their third Pool B game on Tuesday.
