How to read these strikeout matchups
Each starter's score (0–100) weighs his strikeout ability against every hitter in the lineup, hand by hand, then factors in how deep he tends to pitch and his command. Higher means more whiffs point his way. The exact weighting is our own — we project a strikeout count and grade every start against what actually happened.
