Porterfield's unbeaten 112 formed the bulk of the Ireland innings

Ireland kept their World Cricket League hopes alive by claiming a four-wicket victory over Bermuda in Nairobi.

Chasing Bermuda's 275-8, William Porterfield's unbeaten 112 and two late sixes from skipper Trent Johnson helped Ireland reach the target.

All-rounder Kevin O'Brien hit 54 for Ireland after claiming two wickets while Kenny Carroll struck 28 runs.

Niall O'Brien hit 25 runs for the Irish but Eoin Morgan (0), Andre Botha (9) and Kyle McCallan (4) all made little impression with the bat.

Openers Clay Smith (52) and Dean Minors (51) put on 79 for the first wicket with both contributing half centuries.

Kyle McCallan trapped Smith for the first wicket but Bermuda continued to keep the score ticking along with Irving Romaine (26), Lionel Cann (44) and Devon Kemp (35) all contributing useful runs.
