Tristan Stubbs led South Africa to a decisive victory over Ireland in the second ODI of their three-match series, scoring an unbeaten 112 off 81 balls, helping South Africa post 343-4 in 50 overs. South Africa won by 174 runs as Ireland was bowled out for 169, with Lizaad Williams taking three wickets for 36 runs. The Proteas secured the series win with a match to spare, despite resting several regular players. Captain Temba Bavuma retired hurt on 35 due to a soft tissue injury in his elbow, making his participation in the upcoming Bangladesh tour uncertain. Ireland struggled from the start, losing half their side within 10 overs, despite a 52-run last-wicket stand between Graham Hume and Craig Young, which provided some respectability to their score. The final ODI will take place in Abu Dhabi on Monday.
