Most unusual league rule.

[chrono00]

One of my leagues allows up to the completion of the 5th frame for late bowlers. The others are 3rd frame

Yea I don't think that was a usbc rule. Oust leagues I've seen around here allow up to the 5th frame before having to take a blind score for a late Player

I believe that third frame requirement is set by the League or Tournament not the USBC. (It's commonly used on leagues here for players coming in late, no player here to my knowledge though has missed 3 frames because they were out smoking.)

Legal lineup and Tardy players are covered under USBC Rule 109 – Lineup Which says

A team has until the end of the 1st frame of any game of a series to have a legal lineup, Unless otherwise provided by league/tournament rule.

Tardy players who arrive late may be permitted to bowl after a game has started under certain conditions (see 109c. Tardy Players), Unless otherwise provided by league/tournament rule.

Years ago a guy on my team was constantly late for a 6:15 league. He would get there during the 3rd frame week after week.

Along comes day light saving time, and he's there very early.

Practice starts and he's nowhere to be seen.

We start, and around the 3rd frame he shows up...

He had been out in the parking lot talking.
