Pro Leagues are played in Head-to-Head or Rotisserie format and are available in standard (snake) and auction drafts. All Pro Leagues will be composed of 12 teams and will use default scoring settings, with the exception that all protested trades will be reviewed by Yahoo Sports staff instead of league votes.
No. Currently, all Pro Leagues are public leagues. When you sign up, you will randomly be placed in a league with other Yahoo Fantasy Baseball Pro League managers. Yahoo will be the commissioner of all Pro Leagues.
