Ireland defeated South Africa in the second match of the T20I series. Ireland performed well in the T20 series, managing to set a big enough target. T20 and ODI formats are not the same, you have to bat patiently in ODI matches. Many of us thought Ireland would perform well in the ODI series after seeing Ireland's excellent performance in the T20 series. But South Africa team is strong in ODI format, their batsmen have managed to bat well with patience. Where Ireland's batsmen could not bat well with patience. No Irish batsman could score more than 21 runs. Ireland defeated South Africa in T20 series but it is very difficult for them to defeat South Africa in ODI series. South Africa won the first match to take a 1-0 lead. I think Ireland will be whitewashed in the ODI series.
The team balance is simply not there with the Irish team. Some of their players (especially the Adair brothers and Craig Young) are performing really well, while some others are not living up to the expectations. As a result, the performance of the team overall has been volatile. Given the fact that South Africa is without many of their regular players, it was expected from Ireland to give a few upset wins. The results from the 4 matches so far has been pretty mixed. But overall, not too many positives for Ireland.
