Morne Morkel and Robin Peterson picked up three wickets each after JP Duminy stoked a blazing 99 to enable South Africa register a thrashing 131-run win over Ireland and become the first team to qualify for the quarter-finals from Group B.

Ireland did upset England but chasing a demanding 273 against a potent SA attack was never easy, they struggled from the start as Morkel (3/33) and Peterson (3/32) ripped apart the batting line-up to skittle out the Irish for 141 in 33.2 overs at the historic Eden Gardens.

Put into bat, South Africa had a shaky start as their top order collapsed in the absence of leading run-getter AB de Villiers, who is down with a thigh strain.

Prudent batting display by left-handed duo of Duminy and Colin Ingram (46), who stitched together an 87-run partnership for the sixth wicket, led the fightback and guided South Africa to challenging 272 for seven.

South Africa booked their place in the last-eight stage and will take on Bangladesh in their last Group B league match on Saturday in Mirpur.

The loss meant Ireland are out of the quarter-final contention and will face the Netherlands in their last inconsequential group match here on Friday.

Defending the target, South African speedster Morkel sent back Irish opening duo of William Porterfield (6) and Paul Stirling (10) inside the fourth over to give his team a flying start.

Wickets continued to fall at regular intervals as the Irish hope began to fall flat in front of a lively Eden crowd who turned out in large numbers.

Ed Joyce (12) and Niall O'Brien (10) too fell quickly to expose the Irish middle-order as the required run rate began to shoot up.

After being hit by a Kallis bouncer, Kevin O'Brien, who was their star in the win over England, looked for some damage control, building the Irish fightback along with Gary Wilson with a 41-run stand for the fifth wicket.

But the Irish hopes diminished when left-arm spinner Peterson knocked over the dangerous-looking O'Brien (19 from 24 balls) and followed it up with the wicket of Wilson, who looked good in his 31-run innings from 48 balls (4x4, 6x1), in the same over.

Peterson's fine spell exposed the Irish tail reducing them to 107 for seven in 26 overs.

From then on, victory was just a formality for the Proteas as the unproven Irish side was going through the motions.
