First-Pitch Strike Rate
First-pitch strike rate is the percentage of at-bats that start with a strike. It is among the strongest signs of pitching effectiveness and count control.
Getting ahead 0-1 sharply shifts the odds in the pitcher's favor for the rest of the at-bat. Hitters must now defend the zone rather than sit on a preferred pitch or location. Pitchers with a high first-pitch strike rate usually allow lower batting averages and fewer walks overall. The strategic advantage compounds across the whole count. Coaches track this metric specifically because it isolates a pitcher's ability to start at-bats under control. It does so independent of stuff (raw pitch quality) or movement quality.
Break down first-pitch strike rate by pitch type thrown first. Many pitchers have one specific first-pitch offering that is far more reliable than the others and should be leaned on more heavily.
Example
Over a six-inning outing, the pitcher throws a first-pitch strike to eighteen of twenty-two batters faced, a first-pitch strike rate above 80 percent that kept her working ahead all game.
Why it matters
First-pitch strike rate is one of the clearest predictors of a pitcher's overall command and in-game results. It is also fully within the pitcher's control, regardless of opponent quality.
Common mistakes
- Grooving a fastball down the middle just to get ahead, which sacrifices location for the sake of the statistic
- Not tracking the metric at all and relying on gut feel about whether a pitcher is "around the zone" enough
Frequently asked questions
What first-pitch strike rate is considered good in fast-pitch?
Rates above roughly 60-65 percent are generally considered strong at most competitive levels, though exact benchmarks vary by level of play.
Why does the first pitch matter so much more than later pitches in the count?
Because it sets whether the pitcher or the hitter controls the rest of the at-bat. An 0-1 count forces the hitter to defend a much larger effective zone than an 0-0 or 1-0 count.

- Count AdvantageCount advantage describes which side the current ball-strike tally favours, and how each should adjust because of it.
- Pitch CommandPitch command is the ability to reliably place every pitch type in a precise, intended spot. It means more than landing it anywhere in the strike zone.
