What is round robin batting?

Answer 1

Probably refers to frequent changes in the line-up of batters, the term was used in slot racing for arbitrary lane changes to even out the competition- the Orange track or lane , in the center, had the tactical , road-holding advantage. I have heard it applied to a rotation of Pitchers in Baseball, that is only Diamond application. The term probably was derived from the migratory flights of the Robin- a bird that migrates seasonally.
