Test captaincy too much for me to handle: Quinton De Kock

South Africa limited-overs captain Quinton De Kock has said that Test captaincy is "too much" for him to handle. "I could see from a mile away that I [don't] need that on top of my shoulders...I'm wanting to come up the order in Tests...so I don't need that extra pressure," he added. SA are yet to name their Test captain.
