Catcher-Pitcher Communication
Also known as: battery communication, pitch-calling communication
Catcher-pitcher communication is the ongoing exchange of signals, mound visits, and shared read of the hitter that lets a battery agree on pitch selection and location before every pitch.
Beyond simply calling the next pitch, effective battery communication includes the catcher relaying what she is seeing from the hitter's swing and stance, the pitcher shaking off calls she doesn't have confidence in that moment, and both agreeing on target location, not just pitch type. A catcher who calls a great pitch to the wrong location, or a pitcher who nods to a call she is not actually equipped to execute in that at-bat, both break down the same partnership even though neither made a purely mechanical mistake.
Strong battery communication develops over repeated innings together, since a catcher learns which pitches a given pitcher has command of on a particular day and a pitcher learns to trust a catcher's read of opposing hitters. Especially at higher levels, in-game mound visits are used sparingly and specifically — to reset a pitcher's focus, adjust a game plan against a hitter, or confirm signals — rather than as a generic pause in the action.
As a young catcher, ask your pitcher directly between innings which pitches felt good and which did not — don't assume you already know from watching alone.
Example
After giving up a hard-hit ball on a low-and-away pitch call, the catcher visits the mound to confirm the pitcher still has confidence in that location before calling it again later in the game.
Why it matters
A pitcher with excellent stuff can still struggle if the battery is not communicating effectively about location and confidence, since pitch selection is only half the equation — location and shared conviction matter just as much.
Common mistakes
- Catcher calling pitches based purely on sequence patterns without accounting for what the pitcher has command of that day
- Pitcher shaking off calls repeatedly without communicating why, eroding the catcher's confidence in her own reads
- Treating mound visits as generic time-outs rather than using them for a specific adjustment or reset

Motion Lab focuses on individual pitcher and hitter biomechanics rather than in-game communication, so battery communication is best reviewed through game film and direct coaching conversation.
Frequently asked questions
What is a battery in softball?
The battery refers to the pitcher and catcher together as a pair, since their communication and coordination function as a single unit within the defense.
How often should a catcher visit the mound?
Sparingly and with a specific purpose — resetting focus, adjusting the plan against a hitter, or confirming signals — rather than as a routine pause.

- Catcher's RoleThe catcher's role in fast-pitch extends far beyond receiving pitches — they are the field general calling pitches, managing the pitcher's mindset, controlling the running game, and organizing the defense.
- Pitch SequencingPitch sequencing is the deliberate ordering of pitches across an at-bat — using pitch type, speed, location, and movement to set up and exploit a hitter's reactions.
- Pitcher's Workload ManagementA pitcher's workload management is the deliberate tracking and limiting of pitch counts, innings, and rest between outings to reduce overuse injury risk and preserve performance over a season.
- Reading the PitcherReading the pitcher is the baserunner's ability to pick up timing cues in the pitcher's delivery — arm position, release tempo, or body tilt — to optimize their lead and steal timing.
