Wikipedia - Mzansi Super League

The Mzansi Super League (MSL) was a Twenty20 cricket (T20) franchise league held in South Africa. The competition was established in 2018 by Cricket South Africa (CSA) as a replacement for the failed T20 Global League, but only two editions were played before the competition was itself cancelled in favour of the SA20 competition from 2022/23.

The first edition of the tournament took place in November and December 2018. The South African Broadcasting Corporation broadcast all matches domestically on free-to-air channels.

The league consisted of six franchise teams representing different South African cities. Two editions were played under this format before changes were proposed to reflect the wide structural changes that were announced for South African domestic cricket in 2021, but the competition did not run in 2020 or 2021 due to the COVID-19 pandemic and was then cancelled.
