3. Quinton De Kock (Wicket Keeper)

South African opener Quinton De Kock was one of the brightest young talents coming into the World Cup 2015 but could not show even a glimpse of his prowess in the entire World Cup as he only scored 145 runs in the eight matches he played in the tournament. Barring the half century (78) that De Kock scored against Sri Lanka in the quarter finals he failed to get going in any of the contests.
