Optimization diagnostic report

Cristopher Sánchez NL

Cristopher Sánchez's tools (51) outpace production (49) by 2 points. Primary finding: existing slider is present, but its movement shape does not currently cover the desired gloveside-sweep window. Also flagged: Arsenal Gap: Gloveside Drop; Usage Overuse: Sinker. Most actionable fix: reduce sinker usage in favor of higher-performing offerings.

Pregame Scouting Report / starter vs a full lineup
New · starter vs lineup

Scout the whole lineup.

Pick a starter and an opposing team and get the pregame report: the top threats, the easiest outs and exactly which pitch to attack each hitter with, and the sleeper the box score hides, a low-average bat who quietly grades up against this exact arsenal. Click any name for the full 3D dissection.

Comp Constellation / similar hitters, and why
New · profile-shape similarity

Map a hitter's constellation.

Pick any hitter and see who is built like him: a star map where the closest profiles orbit nearest, sized and colored by how alike they really are, over six weighted feature groups from contact quality to sprint speed. Hover a star for why the two agree, click for the radial fingerprint overlay, and follow any comp to his card, projection, or swing lab. A hitter with no true twin gets an honest sparse sky, never a forced match.

Matchup Dissector / pitcher arsenal vs hitter holes
New · any pitcher vs any hitter

Dissect the confrontation.

Pick any pitcher and any hitter and break the at-bat down pitch by pitch in 3D: every pitch in the arsenal flying to the plate with real movement, how often it's thrown, its whiff rate, and exactly where the hitter ranks against that family. The out pitch surfaces itself, the matchup lean is priced against league average, and the holes light up in red.

3D Pitch Lab / batter-POV tunnel viewer
New · interactive 3D

See the tunnel in three dimensions.

Every pitch type's real average flight, reconstructed from Statcast physics and rendered in true 3D from the batter's eye. Orbit the scene, snap to camera presets, and watch the paths share a tunnel before they break apart. Search any pitcher, overlay their best-breaking variants, and export a branded still.

3D Swing Simulator / bat-tracking swing viewer
New · interactive 3D

Watch the swing in three dimensions.

Any hitter's real bat-tracking swing, reconstructed in 3D: an animated batter sweeping his true swing plane, with attack angle, swing-path tilt, attack direction and bat speed annotated against the MLB average. When our optimization model sees a flat path, the recommended swing overlays as a dashed target you can orbit around.

Pitcher diagnostics / tools-production gaps

Hunter Brown

HOU · Stuff-to-Whiff Gap (Command)

70Score 55Tools +14.3Gap

Hunter Brown's tools grade (55) outpaces production (41) by 14 points. Primary diagnosis: changeup grades as the best pitch (whiff 62.4%, csw 42.6%) but is only thrown 10.7% of the time. Secondary signals: Arsenal Shape: Gloveside Drop; Usage Overuse: Four-Seam Fastball. High-fixability path: increase changeup usage to at least league-average for that pitch type.

Diagnostic Profile

Kyle Hurt

LAD · Stuff-to-Whiff Gap (Command)

69Score 52Tools +11.1Gap

Kyle Hurt's tools grade (52) outpaces production (41) by 11 points. Primary diagnosis: existing changeup is present, but its movement shape does not currently cover the desired armside-drop window.. Secondary signals: Arsenal Gap: Gloveside Drop; Usage Underuse: Changeup. High-fixability path: reshape existing changeup to add armside drop rather than developing a new pitch from scratch..

Diagnostic Profile

Reid Detmers

LAA · Arsenal Shape: Armside Drop

68Score 52Tools +6.4Gap

Reid Detmers's tools grade (52) outpaces production (46) by 6 points. Primary diagnosis: existing changeup is present, but its movement shape does not currently cover the desired armside-drop window.. Secondary signals: Arsenal Shape: Gloveside Sweep; Usage Underuse: Changeup. High-fixability path: reshape existing changeup to add armside drop rather than developing a new pitch from scratch..

Diagnostic Profile

Wandy Peralta

SD · Stuff-to-Whiff Gap (Tunneling)

68Score 43Tools +6.2Gap

Wandy Peralta's tools grade (43) outpaces production (37) by 6 points. Primary diagnosis: elite raw stuff but poor pitch tunneling — hitters read pitches early. Secondary signals: Arsenal Shape: Armside Drop; Arsenal Shape: Gloveside Sweep. High-fixability path: pair pitches with tighter release-point similarity and greater late movement divergence.

Paul Goldschmidt

NYY · Launch Angle Too High

30Score 77Tools +15.4Gap

Paul Goldschmidt's tools (77) outpace production (61) by 15 points. Primary finding: elite raw contact quality undermined by swing decisions — the bat is dangerous when it connects. Also flagged: Launch Angle Too High.

Diagnostic Profile

Alec Bohm

PHI · Launch Angle Too Low

29Score 89Tools +6.8Gap

Alec Bohm's tools (89) outpace production (82) by 7 points. Primary finding: groundball-heavy approach with the raw power to drive the ball — leaving fly-ball damage on the table. Also flagged: Contact-Discipline Mismatch. Most actionable fix: elevate bat path to increase average launch angle toward 12-18° range.

Diagnostic Profile

James Wood

WSH · Passive In-Zone Approach

29Score 86Tools +14.5Gap

James Wood's tools (86) outpace production (72) by 14 points. Primary finding: elite raw contact quality undermined by swing decisions — the bat is dangerous when it connects. Also flagged: Passive In-Zone Approach.

ATH · Launch Angle Too Low

29Score 82Tools +14.4Gap

Jonah Heim's tools (82) outpace production (68) by 14 points. Primary finding: groundball-heavy approach with the raw power to drive the ball — leaving fly-ball damage on the table. Most actionable fix: elevate bat path to increase average launch angle toward 12-18° range.
