Cape Town - Former Proteas fast bowler Duanne Olivier has backed his decision to give up Test cricket with South Africa and play for Yorkshire.

The 26-year-old was beginning to blossom into a top-class five-day cricketer, with 48 wickets at a superb average of 19.25 after playing the first of his 10 Tests in 2017.

However, he will not be considered for Proteas selection while under contract with the White Rose outfit.

Olivier has spoken at length about how difficult a decision it was to end his chances of playing for the land of his birth, but feels in Yorkshire he is at the right club.

"Yorkshire, for me, have a lot of history and tradition behind it," he told the club's website.

"They've won many trophies in the past and will again in the future. So when the offer came, it was something I couldn't give up.

"I was very happy about it. Playing my first game, I will be a bit nervous. But it will be good. Playing Test cricket is unique, but I feel I've made the right decision to come to Yorkshire."
