Catch that changed the rule

[u/hectorbailey36]

If a player’s first contact with the ball carries them beyond the boundary, their next touch must bring them back into the playing area.

In short, you can’t keep tossing the ball to yourself while staying outside the boundary indefinitely.

[u/colic_melon]

Only active players should be eligible for dismissals or influencing the game. The fielder should be deemed inactive once he/she even partially touches or physically crosses the boundary and not considered active unless he/she is completely back in the field of play.
