An all-rounder is a cricketer who regularly performs well at both batting and bowling. Although all bowlers must bat and quite a few batsmen do bowl occasionally, most players are skilled in only one of the two disciplines and are considered specialists. Some wicket-keepers have the skills of a specialist batsman and have been referred to as all-rounders, but the term wicketkeeper-batsman is more commonly applied to them. Among the greatest all-rounders have been Imran Khan, George Hirst, Wilfred Rhodes, Chris Cairns, Shaun Pollock, Keith Miller, Garfield Sobers, Ian Botham, Jacques Kallis, Kapil Dev, Richard Hadlee, W. G. Grace, Mushtaq Mohammad, Lance Klusener, Walter Hammond and Andrew Flintoff
