Selected for Ireland's inaugural One Day International against England at Stormont despite a series of low scores in the preceding C&G Trophy matches, Botha vindicated the selectors' judgement by top-scoring with 52 against a first-rate attack including Steve Harmison, Liam Plunkett and Sajid Mahmood. Since then, Botha has evinced a marked aptitude for One Day Internationals, averaging 39.66 in three ODIs to date, with a top score of 56 achieved against the Netherlands during Ireland's victorious 2006 European Cricket Championship campaign.
