Walk Percentage (BB%) FAQ
What does BB% measure?
BB% tells you the percentage of a hitter’s plate appearances that end in a walk.
It focuses solely on walks, leaving out hit by pitch and other ways of reaching base.
Why is BB% important?
A high BB% usually means strong strike-zone judgment and patience, skills that often translate to a good on-base percentage and run production.
What is a good BB% in Major League Baseball?
League average fluctuates around 8 percent.
Anything above 10 percent is considered good, while elite hitters can post 14 percent or more.
Does BB% apply to pitchers?
Pitchers use a related stat called BB/9 or BB% against, which flips the perspective to how often they issue walks.
Lower numbers are better for pitchers.
Can small sample sizes skew BB%?
Yes.
Early in a season or in limited plate appearances, one or two walks can swing the percentage dramatically.
Always pair BB% with sample size context.
