Patient Contact

Works counts and puts the ball in play; modest slug.

Soft contact is the story so far

Ha-Seong Kim walks at a better-than-most clip — better than 73% of qualified hitters. The contact is soft, though — only 12% of qualified hitters hit the ball with less authority. Early-season read — only 85 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.

How to read this chart
Two skills separate hitting styles: not giving away at-bats (walk rate minus strikeout rate) and squaring the ball up when he does put it in play (hard-hit rate). Every dot is a qualified hitter this season; dot size tracks plate appearances. Click any dot to open that hitter's page.

How he fares against lefties and righties

Platoon splits (EB/PA)

Better vs LHP than vs RHP by 0.026 EB/PA (modeled).

50% probable range: +0.006 to +0.045

vs LHP45 PA0.403

vs LHP: shrunk estimate 0.403 EB/PA, 50% probable range 0.376 to 0.432, based on 45 plate appearances. Raw (unshrunk) rate: 0.198 EB/PA. League median vs LHP: 0.425 EB/PA.

Raw vs LHP rate (0.198) 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 righty bat (median 0.034). He sits below the league median against both hands.

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

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
Bases added per 100 pitches of each type — the same scale as the pitcher pages’ “saved/cost per 100”, from the hitter’s side. Every pitch counts: taking a ball adds value, whiffing loses it, and the pitch that ends the plate appearance scores its outcome against the count’s expectation. Values are bases vs the league count-average: +3.5 means his results against that pitch have been worth about 3.5 extra bases per 100 seen. Types with fewer than 50 pitches seen pool into “Other”.

Earned vs. actual

Ha-Seong Kim's contact has earned about 5 more bases than he's actually been credited — his results have run unlucky so far.

over 51 balls in play · walks and strikeouts excluded on both sides

How to read this chart
Every ball he puts in play is worth the bases its exit velocity and direction usually earn. Comparing those earned bases with the bases he was actually credited shows whether his results have been lucky, unlucky, or fair.

Swing

How fast he swings, and what he changes with two strikes. League tracking starts in 2024.

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).

How to read this chart
  • Overhead view of the batter’s box. The dots are his feet, reconstructed from Statcast’s stance measurements — hip position, foot separation, and stance angle — about one second before the pitch. It’s an approximation of his setup, not his stride or swing.
  • Open means his front foot is pulled off the line to the plate; closed means it steps toward it. The average hitter sets up slightly open.
  • The change line above only appears for a sustained month-over-month move that clears normal Statcast noise by a wide margin.
  • The chart is his month-by-month average for whichever measure you pick, this season only. A month needs 25 tracked swings to appear, so an injured or platooned month can be missing. The shaded band and dashed line are where the middle half of hitters, and the median hitter, sat over their whole season.
  • On the angle chart, below zero is an open stance and above zero is a closed one — hover a point (or drag on a phone) and it says which in words.
