Dublin (AFP) - South Africa secured their first win in Dublin since 2012 with a 24-13 victory in a gripping Autumn Nations Series Test over an ill-disciplined Ireland side that at one point were reduced to 12 men.

Tries by Damian Willemse, Cobus Reinach and Sacha Feinberg-Mngomezulu, as well as a penalty try, saw the world champions home against an Irish side that kept the scoreline respectable with courageous defence.

The Irish stayed in the match despite James Ryan receiving a 20-minute red card – the first of his career – and Sam Prendergast, Jack Crowley, Andrew Porter and Paddy McCarthy being sin-binned.

Springbok head coach Rassie Erasmus had never won at Lansdowne Road, even when he was boss of Irish province Munster, but this time he was set fair early on by his side.

Willemse went over in the corner after a lightning-fast passing movement.

Willemse cupped his hand to his ear taunting the Irish supporters before Feinberg-Mngomezulu missed the conversion.

The Springboks had been reduced to 14 men in their previous two Tests and were fortunate Feinberg-Mngomezulu was not sent at least to the sin bin for making no effort to tackle Tommy O’Brien and instead putting his shoulder into the wing’s head.

However, referee Matthew Carley ultimately decided just to award a penalty to the hosts.

Carley, though, had no hesitation in wielding a yellow card at the experienced Ryan after he caught Malcolm Marx in the head at a ruck.

It was doubly costly as Tadhg Beirne’s try was ruled out as a result.

- ‘Glimmer of hope’ -

Carley, keeping a calm head in a febrile atmosphere, gave the Irish some relief when he ruled out a Springbok try owing to a forward pass.

That was about the only good news for captain Caelan Doris and his men, with Carley calling him over to tell him Ryan’s card had been upgraded to a 20-minute red.

Things looked dark indeed for the Irish when Reinach went over as Feinberg-Mngomezulu converted for 12-0 and Prendergast was sin-binned for repeatedly being offside.

Some sides would have wilted being down to 13 men but the Irish reacted positively, triggering huge roars around Lansdowne Road as Dan Sheehan went over.

Crowley converted for 12-7 but minutes later he too was joining fellow fly-half Prendergast in the sin bin, leaving them rudderless with no specialist in that role.

Prendergast’s brother Cian replaced Ryan, just as Crowley was trotting off, after the 20-minute red card was up, but the Irish astonishingly were down to 12 men by half-time.

Carley lost patience and sent Porter to join the two fly-halves and then awarded a penalty try which gave the Springboks a 19-7 half-time lead.

The Irish could not run off fast enough in case Carley decided to hand out another yellow.

Sam Prendergast converted a penalty on his return to the fray for 19-10 but the ‘Boks hit back immediately against the 13 men.

The impressive Feinberg-Mngomezulu sashayed past Jamison Gibson-Park to go over, although he missed the conversion at 24-10.

Both Crowley and Porter returned to make it a 15 v 15 match, the latter coming back on just as his Leinster teammate and Springbok lock RG Snyman was sent on for his 50th cap.

Sam Prendergast stroked over a penalty with 25 minutes remaining for 24-13 to give the hosts a glimmer of hope.

Carley’s well-used yellow card was flashed once again as McCarthy trudged to the sidelines but the sterling Irish defence turned the ball over and Gibson-Park cleared, sparking the biggest roar of the night from the home fans.
