Strikeout-to-Walk RatioK/BB

K/BB stands for strikeout-to-walk ratio in baseball. Strikeouts for every walk a pitcher issues — his command in one number.

How K/BB is calculated

K/BB = K ÷ BB

Tarik Skubal, 2026: 176 ÷ 27 ≈ 6.50

Both halves are outcomes the pitcher controls without his fielders, which makes K/BB steadier from year to year than ERA. Around 3.0 is good and 5.0 is elite.
