The South African all-rounder scored 66 not out as the world's top-ranked team crossed their victory target of 160 under the Duckworth Lewis system with 21 balls to spare.

Ireland were restricted to 152 for eight after rain reduced the contest to 35-overs a side.

South Africa replied with 165 for three and now have four points after chalking up their second victory in the second phase of the tournament.

Kallis didn't have much luck with the ball as he gave away 20 runs in his 3 overs. But he took a brilliant tumbling catch to send back William Porterfield (14) off Shaun Pollock in the 13th over.

Chasing a relatively small target, Kallis came in very early to bat after the loss of AB de Villiers' wicket in the first over of the innings.

But the right-hander along with captain Graeme Smith steadied the innings with a 70-run partnership for the second wicket, before Smith fell for 41.

However, Kallis continued his solid batting, hitting 8 boundaries in 86-ball knock to take South Africa to a well deserved victory.

For the second match in a row, Kallis played a vital innings. He had scored 86 against Sri Lanka in their previous match, which South Africa narrowily won by 1 wicket.
