Outcome Columns
Every percentage below is a share of the first pitches this hitter has seen from this kind of pitcher. A grayed cell means too few of them to say anything.
Swing%How often he swings at the first pitch.
Out/Other%How often the first pitch is hit and the at-bat ends without a hit — an out, a sacrifice, a fielder's choice or an error.
1B%How often the first pitch goes for a single.
XBH%How often the first pitch goes for a double, triple or home run.

About the MLB 1st Pitch board
▶
How each starting pitcher opens an at-bat, and which hitters do damage on the first pitch they see. It isolates a single moment of the plate appearance where tendencies are unusually stable and unusually exploitable.
How to read it
Two views. Top Hitter Matchups lists the hitters most likely to put the first pitch in play, with how often each swings at it and what follows — an out, a single, or extra bases. Starting Pitcher Summary is the other side: how often each starter opens with a strike, how often hitters swing, and how often they put it in play. A starter who fills the zone early against a hitter who attacks the first pitch is the pattern the board exists to find.
