Killer bouncers: The 10 deadliest deliveries ever

7. Mitchell Johnson to Jacques Kallis

Mitchell Johnson bowled a stupendous spell during an Australia-South Africa match in 2008, sending two top order batsmen – Neil McKenzie(caught by keeper) and Hashim Amla (LBW) — to the pavilion within the first three overs. A diabolic delivery hit Graeme Smith hard, and he retired hurt. Mitchell’s fiery energy again produced a deadly bouncer to Jacques Kallis who, upon being hit, stood for a few seconds, then squatted down as blood dripped from his face. The damage was so grave that Kallis had to leave the field.
