Complete Hitter

Above average everywhere, with the bat-to-ball skill to match the thump.

One of the league's most dangerous bats

Ketel Marte creates bases at an elite clip — better than 95% of qualified hitters. No real holes either — the weakest mark (walk rate) sits right around the league average.

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.

Platoon splits

How he fares against lefties and righties

Platoon splits (EB/PA)

Better vs LHP than vs RHP by 0.012 EB/PA (modeled).

50% probable range: -0.008 to +0.033

That interval crosses zero, so the model can’t confidently say which side he’s actually better against.

vs LHP131 PA0.536

vs LHP: shrunk estimate 0.536 EB/PA, 50% probable range 0.515 to 0.558, based on 131 plate appearances. Raw (unshrunk) rate: 0.586 EB/PA. League median vs LHP: 0.425 EB/PA.

Raw vs LHP rate (0.586) 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 switch hitter (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.
  • Ketel Marte 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.

How he hits

What happens when he puts a ball in play

He hits the ball to the pull side most often, and that's where his hardest contact goes.

Best batted balls

Where every ball Ketel Marte put in play landed this season.
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
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

Results have matched his contact quality — Ketel Marte has been credited about what his contact has earned so far.

Earned off his own contact205
Actually credited to him209

over 392 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).

About 70% of switch hitters swing faster right-handed — 33 of them have enough swings from both sides to tell. His right-handed swing is 5.2 mph faster.

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. When his timing is off, it's usually early — about 13 ms ahead of perfect timing. When he misses vertically, it's more often under the ball than over it. More of his mishits come from reaching at pitches away from him than from getting tied up inside.

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.
