Ah, ok ho trovato. Hanno tolto la dicitura “out of shape” tra le motivazione per la sostituzione della palla.

A ball is unfit for play if it is visibly cut, cracked or out of shape

Dal 2019 dovrebbe diventare:

The player may only substitute another ball if it can be clearly seen that the original ball is cut or cracked and this damage happened during the hole being played
