The South Africa cricket team toured Sri Lanka in July and August 2018 to play two Tests, five One Day Internationals (ODIs) and a Twenty20 International (T20I) match.[2] [3] [4] Originally, the tour was for three Test matches, but the third match was dropped and replaced by the ODI and T20I fixtures.[5] The extra ODI fixtures were used as preparation for the 2019 Cricket World Cup.[6]
Ahead of the tour, Sri Lanka Cricket (SLC) named Dinesh Chandimal as the captain of the Test side. However, Chandimal faced disciplinary charges, for his role in alleged ball-tampering during the second Test against the West Indies in Saint Lucia in June 2018.[7] His hearing took place before the start of the first Test, with him found guilty. He received a two-match ban, with Suranga Lakmal captaining the side in his place.[8] [9] After the conclusion of the first Test, the independent Judicial Commissioner handed down a further eight suspension points to Chandimal, meaning that he was also suspended for the first four ODIs of the series.[10]
Sri Lanka won the Test series 2–0.[11]
During the ODI series, South Africa's captain, Faf du Plessis, injured himself during the third match and was ruled out of the rest of the tour, including the one-off T20I fixture.[12] Quinton de Kock was named as the captain of South Africa for the last two ODIs of the series.[13] JP Duminy was also named as the captain of the team for the T20I match.[13] South Africa won the ODI series 3–2.[14] Sri Lanka won the one-off T20I match by three wickets.[15]
