Walks Per StrikeoutBB/K

BB/K stands for walks per strikeout in baseball. Walks a hitter draws for every time he strikes out — the usual one-number read on plate discipline.

How BB/K is calculated

BB/K = BB ÷ SO

Above 1.00 means more walks than strikeouts, which fewer than a dozen qualified hitters manage in a modern season. The league sits near 0.40.

What counts as a good BB/K?

Half of the 241 qualified MLB players in 2026 were at or below 0.43. Clearing 0.72 put a season in the top tenth of the league.
