Attack Zones

Baseball Savant's attack zones. Heart = the middle of the zone (hittable); Shadow = the edges, just in or just out (where command shows); Chase = well off the plate, only good if hitters swing; Waste = nowhere near it. Shadow CSW% = called + swinging strikes on edge pitches; Chase Swing% = how often hitters went after his chase pitches.

Release Point Consistency

SD = how much the release point moves around (feet). A rising SD or a drifting weekly average is often an early mechanics or fatigue signal.

Movement by Pitch

vs Avg = inches above/below the average same-handed pitcher's version of that pitch (horizontal: + = more arm-side run).

One row per pitcher x pitch type, sorted by Stuff+. Chase% = swings at out-of-zone pitches / out-of-zone pitches; Whiff% = whiffs per swing; CSW% = called + swinging strikes per pitch.

Expected stats against: xBA / xSLG per at-bat and full xwOBA per plate appearance (contact valued by exit velocity + launch angle; walks, HBP and strikeouts as they happened). xRA (expected runs allowed per 9 — TrackMan has no earned runs) puts xwOBA on the RA/9 scale; xFIP is FIP with a league-average HR-per-fly-ball rate. Sorted by xwOBA (best first). Negative wOBA-xwOBA = results better than the contact allowed.

Savant-style pitch movement: induced vertical break (IVB) and arm-side horizontal break, each compared with the league average for the same pitcher hand, pitch type and 2-mph velocity band (positive = more rise / more arm-side run than average). One row per pitcher x pitch type, sorted by IVB vs average.

xOBP isn't shown — it requires a trained expected-outcome model fit the same way xBA/xSLG are, and that model doesn't output an xOBP component. Spin/Extension are ranked assuming higher is better, which is a simplification (ideal spin and extension vary by pitch shape and arm slot).

Run Value is estimated from this dataset's own run expectancy by outs (0/1/2 outs before the play) — there's no base-occupancy column in this export, so it can't credit/penalize who was on base the way a full base+out (RE288) model would, but it does adapt to the loaded data's actual run environment instead of using fixed generic weights.

One row per hitter: slash line, wOBA / xwOBA (expected from exit velocity + launch angle), K% / BB%, contact quality and swing decisions. Sorted by xwOBA.

Sprint Speed, OAA, Arm Strength, Bat Speed, Squared-Up Rate, and Swing Length aren't shown — those require biomechanical/bat-sensor tracking (e.g. Hawk-Eye, Blast Motion) that isn't present in ball-flight-only Trackman exports.

Run Value is estimated from this dataset's own run expectancy by outs (0/1/2 outs before the play) — there's no base-occupancy column in this export, so it can't credit/penalize who was on base the way a full base+out (RE288) model would, but it does adapt to the loaded data's actual run environment instead of using fixed generic weights.

Team-wide version of the Player Card's Swing/Take Zone Profile: average run value per pitch, split by whether the hitter swung or took, using the same batting-team run-value convention (positive = good for the hitter) as the rest of this app's run-value columns.

TrackMan-tracked games only. Records are tracked W-L, not official records; FIP is on the runs-allowed scale (no earned-run data).


Championship Formula

Teams that meet every indicator historically tied to a title run (our version of College Baseball Insiders' formula, from TrackMan-tracked games): .500+ road record (can win anywhere), top-25 strength of schedule (proven against quality), top-25 Adj Pitching+ (staff depth) and wRC+ of 100+ (can score anywhere). Sorted by criteria met, then Adj Team Rating.

D1 baseball analytics built on TrackMan pitch-tracking data
Every D1 team and player in our TrackMan data — seasons 2023, 2025, 2026, plus Career. Pick one or more seasons in any filter bar.

Seasons & updates

We have the 2023, 2025 and 2026 D1 seasons from TrackMan, with Stuff+, Location+ and the expected-stat models trained on all of them together. The 2027 season will update every night — new games, box scores and schedules land on the site the next morning.

What's inside

  • Search — any player or team; Enter opens the highlighted result. Team names and logos everywhere link to that team's page.
  • Player Page — one scrolling page per pitcher or hitter: percentile rankings, year / position, stat lines by split, month and times through the order, official season stats, pitch arsenal, movement and release, zone profile, game by game.
  • Pitcher — player card, pitch usage (by count and times through the order), Stuff+, command with Savant-style attack zones, game log, platoon splits, K/BB, season and daily reports.
  • Hitters — player card, heat maps, platoon splits, batted-ball profile and spray charts, swing decisions, two-strike approach, reports.
  • Leaderboards — pitchers and hitters by season or Career, filterable by team, conference, handedness and qualifier, with D1 averages.
  • Teams — a page for every team (roster, full schedule with tracked / not-tracked games and clickable box scores, leaders, splits, staff arsenal) plus Team Stats, Championship Formula, Heat Check, Matchup and Scouting Quadrant.
  • Games — Around D1 (Stuff+ leaders, hardest-hit balls) and every tracked game: line score, box scores, hardest-hit balls, pitch velocity and pitch-by-pitch.

How to read it

  • Percentiles: red = great, gray = average, blue = poor — always from the player's point of view (a low BB% is red for a pitcher).
  • RA/9 and xRA, not ERA: TrackMan can't separate earned from unearned runs. FIP, xFIP and SIERA are scaled to the league's RA/9.
  • Expected stats: xBA / xSLG / xwOBA come from exit velocity and launch angle on balls in play (fouls never count toward EV), calibrated each season.
  • Stuff+ / Location+ / Offense+ / Pitching+: 100 = D1 average; higher is better. Team ratings are opponent-adjusted and per plate appearance, so more tracked games never raise a rating by itself.
  • Tracked games only: TrackMan stats cover the games TrackMan recorded. Official numbers (marked as such) cover every game.

Data sources & accuracy

  • TrackMan — every pitch, swing and batted ball: velocity, movement, spin, location, exit velocity and launch angle. Practice, intrasquad and non-D1 games are left out.
  • The Baseball Cube — year in school, positions, official season stats, conferences, official records and 2023–2025 schedules. Catchers are confirmed from TrackMan (who caught each pitch).
  • School athletics sites — official box scores, used for 2026 schedules and to check TrackMan game by game.
  • Checked against the official box scores: across about 44,000 official box scores, TrackMan's counting stats in tracked games match within about 1% (hits, walks, strikeouts, batters faced, outs), and 92–99% of individual player lines match exactly per game. Pitcher runs can differ because officially a run is charged to the pitcher who put the runner on base; TrackMan only knows who was pitching when it scored. Sac flies TrackMan tagged as outs are counted as sacrifices.
