Fantasy baseball leagues, unlike most other sports, generally use rotisserie scoring. Most other sports use the head-to-head method (detailed below), and this is an option in baseball, but most baseball leagues go with rotisserie scoring. Rotisserie scoring awards points to each team based on their position in the standings in each category. For example, in a 12 team league, the fantasy owner with the highest total of RBI would receive 12 points in the standings, while the person with the least RBI would receive one point, with the others falling into place in between. This is done for each scoring category, and the scores are then tallied to determine the winner.
The aforementioned head-to-head scoring method is not as popular in baseball as in other sports, but it is still an option. In this scoring method, two teams in the league match up against one another each week, with the winner getting credit for a victory and the loser taking a defeat. Records are tracked and standings work just like they would in regular baseball. At the end of the season, some leagues have their own playoffs, pitting the top six or eight teams against one another in a bracketed tournament to determine the champion. So, like in real life, the best team during the regular season may not end up being the league champion.
