In cricket, pinch hitter or slogger is the usual term for a batsman (not a substitute, unlike in baseball) promoted up the batting order in order to score quick runs. As attempting to score runs quickly involves playing more aggressive shots and thus an increased likelihood of being dismissed, it is generally considered unwise for a top-order batsman to attempt this. Therefore, a lower-order batsman (such as a bowler) is sometimes promoted. There is less importance placed on his wicket, so he can play with more freedom. This is an important tactic in One Day International cricket, with its occurrence in Test cricket far less regular.
The term was relatively recently introduced to cricket, and was unfamiliar to many cricket followers before the 1992 World Cup. New Zealand employed a slightly different form of the tactic to considerable effect with Mark Greatbatch playing the pinch-hitting role. This was among other innovative tactics New Zealand employed successfully during the round-robin stage to reach the knockout stage.
It has since been used throughout limited overs cricket, with the aggressive batsmen known as "pinch-hitters."
However, "pinch hitter" usually refers to an aggressive batsman moved up the batting order from his usual place, used in situations where scoring runs quickly becomes more important than keeping wickets in hand.
Pinch hitters are known for their big hitting and high strike rates. However, they sometimes lack the technique of higher-class batsmen and therefore often go out for low scores through their excessive attacking. This is not the same as a "nightwatchman" used in Test and first-class matches.
