South Africa's wicketkeeper-batsman Quinton de Kock beleives teams must participate in pink-ball Tests despite the concept not being perfect. "I have played one day-night Test and yes, there are some rough edges which need to be taken care of, but it's a good concept and for fans, it's awesome," De Kock said while launching some practice tools promoted by Omtex at MIG Cricket Club in Bandra yesterday.
