In baseball, the term “BB” is often used in reference to pitching and refers to a base on balls, which is also known as a walk. A base on balls occurs when a pitcher throws four pitches that are outside the strike zone and the batter does not swing at any of them.
When a batter receives a base on balls, he is awarded first base without having to hit the ball. The pitcher is charged with giving up a walk, and this statistic is recorded as part of his pitching line.
The number of walks that a pitcher gives up can be an important indicator of his performance on the mound. Walks can lead to base runners, which can in turn lead to runs scored by the opposing team. For this reason, pitchers who are able to limit their walks are generally considered to be more effective than those who struggle with control.
In addition to the BB statistic, there are several other pitching statistics that are commonly used to evaluate a pitcher’s performance. These include earned run average (ERA), strikeouts per nine innings (K/9), and walks plus hits per inning pitched (WHIP).
The earned run average is a measure of how many earned runs a pitcher gives up per nine innings pitched. A pitcher who has a low ERA is generally considered to be more effective than one with a high ERA.
Strikeouts per nine innings is a measure of how many strikeouts a pitcher gets per nine innings pitched. This statistic is often used to evaluate a pitcher’s ability to strike out batters and get out of tough situations.
Finally, walks plus hits per inning pitched is a measure of how many baserunners a pitcher allows per inning pitched. This statistic takes into account both walks and hits, and is often used as a more comprehensive measure of a pitcher’s ability to prevent opposing teams from scoring.
In summary, in baseball, the term “BB” is used to refer to a base on balls, which occurs when a pitcher throws four pitches outside the strike zone and the batter does not swing. Walks can be an important indicator of a pitcher’s performance, as they can lead to base runners and runs scored by the opposing team. In addition to BB, there are several other pitching statistics that are commonly used to evaluate a pitcher’s performance, including ERA, K/9, and WHIP.
