Detroit·Home stadium Comerica Park·Park factor 96
This page = Statcast 4 factor (xwOBA · Barrel% · Hard Hit% · Launch Angle) deep-dive layer. Season stat summary = /en/mlb/team/DET.
Currently shown = factor definitions + ranges. Team season measurements (Baseball Savant aggregates) integration ETA carry-over. Measurement layer = `mlb-base.ts` factor pipeline + `baseball-savant.ts` scraper.
—
Measurement ETAExpected wOBA estimated from launch angle + exit velocity. Removes luck (defense / ballpark / weather) to measure true contact quality.
Why it matters: Eliminates result noise from wOBA → more meaningful in small samples.
—
Measurement ETABarrel = minimum launch angle + exit velocity threshold met = avg .500+ AVG / 1.500+ SLG expected. Percentage per plate appearance.
Why it matters: Hard contact frequency = raw signal for home run + extra-base production capacity.
—
Measurement ETAShare of batted balls at 95 mph+ exit velocity. Lower threshold than Barrel = larger sample, more stable signal.
Why it matters: 95+ mph exit velocity sharply increases hit probability. Primary input axis for xwOBA.
—
Measurement ETAAverage batted ball launch angle. 10–25° = line drives / 25–35° = fly ball sweet spot.
Why it matters: The angle axis of Barrel. Same exit velocity produces different outcomes based on angle.
