positions according to circumstance are less dramatic; the strike zone and smaller angle of fair territory limit the usefulness of some strategies which cricket makes available to batsmen. The chief occasion on which fielding placement differs markedly from the usual is the presence of a pull, or dead-pull, hitter at bat (such hitters almost never, except on the rare occasion of a fluke or mishit, hit the ball in any direction except towards the same side of the field as they stand at the plate, i.e., a right-handed pull hitter hits everything toward left field). In such case the fielders will move so far in the direction of the pull that one half of the field is almost completely unprotected. This is called an infield shift or overshift. A six-man infield has also been used when circumstances warrant. For the great majority of batters, however, the traditional fielding arrangement is used, with minor changes in position to accommodate the batter's power or bat-handling ability, the location of runners, or the number of outs. (For example, with a base runner on third with less than two out, the importance of fielders being able to throw quickly to home plate on a bunt is increased, and the infielders will play closer to home plate.) However, baseball has no equivalent of cricket's close-in fielders, because it is impractical to have fielders so close to the bat as they would have virtually no chance of latching onto a ball travelling so fast. It is possible to place a close-in fielder to catch a bunt, but this practice is almost never followed except in specialised circumstances such as a pitcher being forced to bat late in a game, with less than two outs and the opportunity to drive in a run. The team's best chance to score in such a situation may be to sacrifice bunt and may warrant the first or third baseman playing halfway up the line to cut off the run at home. Use of signals, commands, and discussion Coaching strategy and tactics In cricket, coaches cannot intervene or direct gameplay; the captain must make all the calls once the players are out on the field. However, the coach may convey messages to the captain or the players at any time, since there is no restriction on signalling or speaking to players on the field. In dynamic situations, like a run chase
