Ireland suffered a 139-run defeat in their series-opening ODI in Abu Dhabi as South Africa avenged Sunday's T20 loss.Ireland's historic 10-run victory on Sunday - the first ever against South Africa - saw the T20 series finish in a 1-1 draw but Paul Stirling's side were skittled for 132 in 31.5 overs responding to South Africa's 271 for nine in Wednesday's one-day international.George Dockrell top-scored for Ireland with 21, with Andy Balbirnie and Curtis Campher each reaching 20 but failing to kick on, with both batters dismissed by Lizaad Williams, who claimed four for 32.Mark Adair had earlier claimed four for 50 and Craig Young three for 45 to drag back the Proteas, who looked set for a higher score after reaching 191 for three in the 35th over.But even at that stage they had enough, thanks to opener Ryan Rickelton's 91 off 102 balls plus Tristan Stubbs' 79 off 86 deliveries.The match saw captain Stirling win his 400th cap for Ireland across all formats in the same venue where he made his debut back in 2008, becoming the most-capped male Irish athlete in any team sport in the process.The second of Ireland's ODIs against South Africa will take place on Friday, before the third and final meeting next Monday.South Africa 271-9 (50 overs)Ireland 132 (31.5 overs)
