Running/Extra fitness should be accepted as a viable step to increase alertness and mental performance during practices and games. Running for physical mistakes (i.e. striking out or making a throwing error) is counter productive. However, running to increase physical and mental endurance has always been and will continue to be a part of athletics. Every sport uses extra conditioning to pose pressure situations in athletics. In basketball, one person is selected to shoot a free throw, if he misses, than the whole team has to do a suicide run. You can make that process realtive to any sport, most of the time it is used to create intensity, pressure situations and team unity. Extra running should not be distributed out of anger or disgust but can be used in an appropriate way as part of the educational process. Run to increase the mental edge so important in baseball, but do not be a sore loser and run the players because they lost. If the team loses by 16 runs two games in a row, introspection by the coach may be a good idea, something is not being done right.
