Performance
Unwashed shirts, fixed routines, lucky numbers. These are the newest superstitions in this set and the best studied, because athletes perform them openly and researchers can watch.

What exactly is believed
The no-hitter jinx
In baseball nobody mentions a no-hitter in progress, or it will be broken.
Stepping over the line
Many athletes avoid stepping on the foul or sideline on the way on or off the field.
Pre-game routine
The same meal, music, order of dressing and warm-up are repeated before every match.
