In baseball, BB stands for base on balls, which refers to getting on base by taking four balls during an at-bat. This is one of the ways to score runs and is important for both hitters and pitchers. The abbreviation BB is derived from “base on balls,” which is also known as a walk. A player can only reach first base by hitting the ball, getting hit by a pitch, or taking four balls. A walk awards the hitter only one base, but the baserunner can attempt to steal bases to advance further.

There are three ways for a player to reach first base: BB, HBP (hit by pitch), and IBB (intentional base on balls or walk). While a walk does not impact a player’s batting average, it does factor into their on-base percentage, which measures how often a player safely reaches base when they are hitting.

Pitchers want to limit the number of walks they give up, as it can give the hitter a free pass to reach base. BB/9 is a stat used to measure the number of walks a pitcher gives up per nine innings pitched. Hitters who are good at taking walks show a good eye at the plate and can help their team score runs.

Barry Bonds holds the record for the most walks in a season and career, with 232 walks in 2004 and 2,558 walks in his career, respectively. A BB is recorded on a baseball scorecard by the official scorekeeper by writing BB next to the line from home plate to first base for the hitter.

In summary, BB means base on balls or a walk in baseball. Getting on base via a walk is an essential part of scoring runs, and it is important for both hitters and pitchers. While it does not impact a player’s batting average, it factors into their on-base percentage and OPS. Pitchers want to limit the number of walks they give up, and the BB/9 stat measures this. Barry Bonds holds the record for the most walks in a season and career.
