Okay....I had a short lunch. I read this topic too quickly. Now that I have time I will answer:
You can do this:
Rule 104d/2 - What do we do if our league starts the season with an uneven number of teams and a team is added during the season?
USBC recommends the board meet and choose one of the following options:
Option 1: The league allows the new team to make up the games unopposed and match the scores with teams that previously bowled what was considered a nonexistent team.
Option 2: The league allows the new team to baowl against their averages in making up any missed games.
Option 1 is best answer to this.
Always the last one to POST!
