Games behind


In sports in Canada and the United States, the phrase games behind or games back (often abbreviated GB), is a common way to reflect the gap between a leading team and another team in a sports league, conference, or division. It is calculated using the following formula, in which TeamA is a leading team, and TeamB is a trailing team:

This formula gives the GB for TeamB. (One also says that TeamA is that many games ahead.) A leading team itself is always zero games behind, by definition, and this is typically indicated in tables by a dash rather than a zero.

For example, if the Cleveland Indians are three games behind the Kansas City Royals, Cleveland would have to win three games, and Kansas City would have to lose three, to tie for first by a GB calculation. A "games behind" situation changes rapidly when two teams contesting the lead play each other, since in each such game the GB will change by plus or minus one. In this case, Cleveland could pull even with Kansas City by a clean sweep of all games of a three-game series.

Note that a team may be ahead of a team that has more wins. For example, a team with a record of 65 wins and 53 losses is one-half game ahead of a team with a 66–55 record. Also, two teams with different win-loss records may both be leading teams, if one team has the same number of additional wins and additional losses compared to the other.

The GB calculation is often used in professional baseball and basketball, where tie games are not permitted, and to a slightly lesser extent in American football (where ties are rare and are officially count as half a win and half a loss, but can be omitted entirely when calculating GB since the "wins minus losses" values for a given team will be the same either way) and in ice hockey (where standings points are used). Usually, in tables of standings in newspapers and magazines kept during the season, teams are ordered by the teams' winning percentages, with the number of games they are behind the division leader supplementing the table. On rare occasions, it is possible (and has occurred) for the team with the second best winning percentage to lead the team with the best winning percentage in terms of games back. This usually occurs during the early portion of a season when teams have played an unequal number of games. For example, if Team A has a record of 23–13 and Team B has a record of 26–15, Team A would be recognized as having a better record by virtue of their .639 win percentage to Team B's .634 percentage, and would be listed first in the standings. However, Team A would still be one-half game behind Team B.
