Cricket South Africa (CSA) has expressed its disappointment after allrounder Duanne Olivier signed a three-year deal with county side Yorkshire on Tuesday, subject to clearance from Kolpak regulations, to turn his back on international cricket.

In a statement released immediately after Yorkshire made the announcement, CSA said that it was disappointed with Olivier, who rejected a national contract and decided to continue his career as a Kolpak player in the England county championship.

We find it extremely disappointing that Duanne has taken this step after all the opportunities we have given him, particularly over the past season and going forward, to live his dream of being an international cricketer, CSA Chief Executive Thabang Moroe said.

He was upgraded to a national contract during the current season on the strength of his outstanding performances in our Test squad and we offered him a two-year contract which would have given him financial security through to the end of the 2020-2021 season.

He was not short of opportunity either as he played in all six Castle Lager Test matches against Pakistan and Sri Lanka during the current summer and was also considered for white ball selection.

If one looks at the bigger picture this is not good news for the global game either that a player who has just broken into the top 20 on the ICC Test match bowling rankings for the first time should opt effectively to bring down the curtain on his international career in favour of playing only in domestic leagues.

Coach Ottis Gibson too echoed the same sentiments.

We are naturally disappointed with Duanne s decision to sign a Kolpak contract. He has been a key feature for us this summer and was without a doubt one of our standout performers. We held several meetings with him regarding his future with the Proteas throughout the summer and even offered him a two-year contract.

To see him cut short a promising international career is disappointing. Ultimately, it was a decision we could not control despite our best efforts.
