A disciplined contact hitter

Geraldo Perdomo walks at an elite clip — better than 96% of qualified hitters. The contact is soft, though — only 12% of qualified hitters hit the ball with less authority.

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.

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

A wider split than the typical switch hitter's (median 0.015). He's above the league median against both hands, so the weaker side is still a strength — not a hole.

He sits in the league's top quarter vs both lefties and 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.
  • Geraldo Perdomo switch-hits — he can choose the platoon-advantaged side almost every plate appearance, so a small gap here is expected. It is not missing data or a modeling error.
  • 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

Geraldo Perdomo's contact has earned about 19 more bases than he's actually been credited — his results have run unlucky so far.

Earned off his own contact188
Actually credited to him169

over 397 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.

Batting left

Lg median

Swings slower than most hitters. His swing is shorter than most hitters', with a typical attack angle. Cuts his swing down about as much as most hitters with two strikes. From both sides, his bat travels on a steeper path than most. Batting right, his bat speed is up 2.8 mph since April — a real change, not day-to-day noise.

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.
  • “A real change” means the move from his first full month to his latest one is more than three times its own margin of error, and big enough to matter, after subtracting the league’s own drift — bat speed rises about half a mile an hour across the league every spring, and that is not a swing change.
  • 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).

About 70% of switch hitters swing faster right-handed — 33 of them have enough swings from both sides to tell. His left-handed swing has a 7.1° steeper attack angle.

How to read this chart
  • Both sides need at least 100 competitive swings for this card — below that, the difference between them is mostly measurement noise.
  • Each swing is compared against the league median for that batting side, so a left-handed swing is measured against other left-handed swings.
  • We only name a difference when it is more than three times its own margin of error and big enough to matter. For a handful of switch hitters nothing clears that bar, and the two sides really are the same swing.

Timing

Early or late, over or under — how his swing meets the pitch. Tracking starts mid-2023.

Squares the ball up more often than most hitters. His misses split about evenly between early and late. When he misses vertically, it's more often under the ball than over it.

Middle half of the league
How to read this chart
  • Perfect contact — a swing that is centered (barrel within 4 inches of the ball horizontally), on time (within 7 milliseconds of ideal timing), and lined up (within 2 inches vertically), all at once. A swing missing any of the three counts as flawed.
  • Miss distance — on swings and misses only: how far the barrel half of the bat passed from the ball, in inches.
  • Timing numbers are Savant’s season-to-date figures. Switch hitters have both sides combined — no side-by-side timing split exists.
  • League comparisons cover hitters with 100+ tracked swings this season. Tracking starts in July 2023.

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.
