Hits it hard with little to show for it

Sean Keys squares the ball up — harder contact than 94% of qualified hitters. The strikeouts pile up, though — only 9% of qualified hitters whiff more often. Early-season read — only 37 plate appearances so far.

How to read this chart
Each spoke is a skill estimate adjusted for sample size — not raw season stats — so farther out = better. Spokes are the metric itself; ↓ marks a rate where a LOWER number is better. Percentiles vs. 499 qualified hitters — 50+ plate appearances. He hasn't reached that bar himself, so he is measured against them rather than counted among them.

How he fares against lefties and righties

Platoon splits (EB/PA)

Better vs RHP than vs LHP by 0.077 EB/PA (modeled).

50% probable range: +0.056 to +0.097

vs LHP3 PA0.357

vs LHP: shrunk estimate 0.357 EB/PA, 50% probable range 0.327 to 0.389, based on 3 plate appearances. Raw (unshrunk) rate: 0.357 EB/PA. League median vs LHP: 0.425 EB/PA.

vs RHP34 PA0.434

vs RHP: shrunk estimate 0.434 EB/PA, 50% probable range 0.408 to 0.463, based on 34 plate appearances. Raw (unshrunk) rate: 0.250 EB/PA. League median vs RHP: 0.436 EB/PA.

Raw vs RHP rate (0.250) is off this scale — small samples like this are exactly why the shrunk estimate (the dot) is the trustworthy number, not the raw one.

Above league medianBelow50% probable rangeHis raw rateMiddle half of the league

About the typical split for a lefty bat (median 0.080). Against lefties he sits below the league median — a genuine platoon vulnerability.

He sits in the league's bottom quarter vs lefties and the league's middle half vs righties.

How to read this chart
  • Tap or hover any mark for its number, or tab to a row for all of them.
  • His raw rate is the unshrunk number against that hand — small samples make it noisy, which is why the model pulls his estimate toward a more trustworthy value.
  • “Middle half of the league” is the 25th–75th percentile of all hitters against that hand.
  • Shrunk splits beat raw splits decisively at low PA counts and converge with them as playing time builds — individual platoon gaps need roughly 1,000+ PA vs a hand before the raw number alone can be trusted.

How to read this chart
Dot color is estimated bases (EB) — what the contact was worth, regardless of what the defense did with it. So a dark hollow ring in the outfield is a crushed ball that got caught. Tap or hover a dot or a row to link the two, and use the ▶ links to watch a play on Baseball Savant.

How to read this chart
  • Competitive swings: bunts and checked-type swings under 50 mph are excluded, so these numbers sit a touch below the bat speeds Savant publishes, which use a different cut.
  • League tracking starts in 2024, and early 2024 has small gaps — about 93% of swings that season have a reading.
  • Swing length — how far the sweet spot of the bat travels during the swing.
  • Attack angle — the bat’s upward or downward tilt through the zone.
  • Swing path tilt — how steep the bat’s path is.
  • None of these is better or worse on its own — swing style trades power against contact (the fastest and slowest swings in the league both belong to stars).
