Softball pitching is unlike anything else in sports. The rise ball that disappears above the letters. The drop that vanishes at the knees. The off-speed pitch that makes a hitter look completely helpless—until the fourth time they see it in a tournament and start sitting on it. Knowing which pitches are working, in which locations, against which types of hitters, is the difference between guessing and coaching. That's what pitch charting for softball coaches is built to reveal.
Why softball pitch charting is different
Softball pitch charting shares a lot of DNA with baseball, but there are meaningful differences that coaches need to account for.
The pitch repertoire is different. Where a baseball pitcher might feature a four-seam fastball, two-seam, slider, and changeup, a softball pitcher's arsenal might include a rise ball, drop ball, curve, screwball, change-up, and fastball inside vs. outside. These aren't just different names—they behave differently in the zone, and they need to be tracked as distinct pitch types with their own location and outcome data.
The delivery is different. Underhand pitching mechanics mean the ball enters the zone on a very different arc. The rise ball is genuinely rising. The drop is breaking sharply down. The relationship between pitch type, location, and batter outcome in softball doesn't map cleanly to baseball intuitions. Your data needs to be specific to your sport.
Hitter tendencies are different. The same batter who handles a fastball up in the zone may completely fall apart against a drop ball down and in. Or she may chase rise balls all day until the fifth time she faces the same pitcher. Pitch charting by batter handedness helps you spot these patterns—but you need enough data to see them.
What to chart in a softball game
Effective softball pitch charting doesn't require tracking every conceivable detail. It requires tracking the right details, consistently, every game. Here's what matters:
Pitch type
Record the name of the pitch exactly as your pitcher knows it. Use whatever terminology your program uses—rise ball, rise, riseball; drop, drop ball, drop curve—but be consistent. Inconsistent naming across games makes long-term analysis impossible.
Location zone
Divide the strike zone into sections. A simple 3x3 grid (inside/middle/outside horizontally, up/middle/down vertically) gives you nine zones that are easy to identify and log in real time. Track locations even on balls—a ball in the dirt tells you something different than a ball high and away.
Count
Record the ball-strike count at the time of the pitch. Pitch selection at 0-0 should look very different from pitch selection at 2-0 or 1-2. Without the count, your data can't tell you whether your pitcher is pitching aggressively ahead in counts or surviving from behind.
Outcome
Called strike, swinging strike (whiff), foul ball, ball, and in-play result. For in-play results, note whether the ball was a ground ball, fly ball, or line drive, and whether it was a hit or out. Sub-outcomes can be filled in immediately after the play.
Batter handedness
Right-handed or left-handed. Batter handedness splits are some of the most actionable data a softball coach can have. If your pitcher's rise ball is dominant against right-handed hitters but gets driven by lefties, that's a pitch-calling decision that can change today's game.
The stats that matter most for softball pitchers
Strike % and first-pitch strike %
Strike percentage measures how often the pitcher throws a strike overall. First-pitch strike percentage (FPS%) measures how often they get ahead on pitch one. In softball, FPS% is particularly important because plate appearances where pitchers fall behind early tend to produce disproportionately more walks and hard contact.
Target FPS% of 60% or better for competitive-level softball pitchers. If a pitcher is throwing 65% overall strikes but only getting ahead 42% of the time, she's working out of trouble all game instead of pitching from a position of strength.
WHIFF% by pitch type
Swing-and-miss divided by total swings, broken down by pitch type. WHIFF% tells you which pitches in your pitcher's repertoire are generating genuine swing-and-miss—the kind that doesn't depend on the count or a generous umpire.
In softball, rise balls and drop balls often have dramatically different WHIFF% numbers depending on who's in the box and how high/low they're being located. A rise ball with 35% WHIFF% is elite. One with 8% is being tracked well by hitters and needs to come out of two-strike situations.
BAA (batting average against) by pitch type and location
How often are hitters getting hits when they put a specific pitch in play? BAA by pitch type and location reveals your pitcher's actual vulnerabilities. The changeup might carry a great overall WHIFF%, but if the version that catches the inside edge against left-handers has a .480 BAA, that's a combination to avoid.
Net Impact
Some pitch charting approaches combine WHIFF%, called strikes, and contact quality into a single effectiveness score per pitch type. Pitch MetRx calls this Net Impact—it's a quick read on which pitches are actually winning plate appearances for your pitcher on a given day.
How to use pitch charting data in the dugout
The most valuable pitch charting data isn't historical—it's immediate. What you log in the first two innings can change how you call pitches in the fourth.
If your pitcher's drop ball isn't generating any swing-and-miss through the first 12 pitches you've thrown it, and batters are making solid contact, you have objective signal that the pitch isn't working today. Maybe the release point is inconsistent. Maybe hitters have a solid look at it from the previous game in the tournament. Either way, the data gives you a real conversation to have at the next mound visit instead of "trust your stuff."
Pitch MetRx includes a mid-game report that updates automatically after every pitch. You can pull it up between innings without pausing your logging. It shows real-time strike %, FPS%, WHIFF%, BAA, and a complete breakdown by pitch type—filterable by batter handedness with one tap. It's the closest thing to a live analytics feed that coaches have had access to at the non-professional level.
Building a pitch charting habit across a season
Individual game charts are useful. A full season of charts is transformational.
When you log every outing for a pitcher across a full season, you can track development in ways that aren't visible game-by-game. Is the rise ball WHIFF% trending up after bullpen work on release height? Has the drop curve started generating more called strikes as command improved? Is first-pitch strike rate climbing as your pitcher gets more confident attacking hitters early?
These developmental questions have real answers when you have the data. They stay guesses when you don't.
Pitch MetRx stores every pitch from every game under a pitcher's profile. Lifetime stats aggregate across the full season. Custom date-range reports let you compare any two stretches of the season side by side. And PDF or CSV exports let you share the data with the pitcher, their parents, or a college coach who wants a full statistical picture.
Getting started
The barrier to pitch charting in softball used to be the manual work—writing on paper, counting by hand, building spreadsheets. That barrier is gone.
With Pitch MetRx, you create a free account, add your pitcher and her specific pitch types, and start logging from your phone. The report is ready the moment the game ends. No paper, no counting, no spreadsheet. Just the data your pitcher needs to develop and the data you need to make better calls.
Pitch MetRx is a pitch charting app built for softball and baseball coaches who want real-time data without the complexity. Log pitches from the dugout, generate post-game reports instantly, and track your pitchers across a full season — all in one place.
