Can you get a 300 ring in a non sanctioned league?
Only games bowled under a sanctioned league may receive
recognition by the sanctioning organization that the league
sanctioned with.
For example, if the league is based in the US and did not
sanction in USBC then scores will not be recognized for any USBC
awards, including the 300 ring.
Even if bowlers who are members of a non-sanctioned league bowl
a 300, they can not qualify for any USBC awards if the league did
not sanction.
