How to read this chart
Each spoke is a skill estimate adjusted for sample size, not a raw season stat, and farther out is better. A ↓ marks a stat where a lower number is better, and its spoke is flipped so farther out still means better. The middle ring marks the league median and the outer ring the league best. EB/PA is estimated bases, HR% home runs, BB% walks and K% strikeouts, each per plate appearance, and Hard-hit% is balls hit 95 mph or harder. Percentiles compare him with 534 qualified hitters, the ones with 50 or more 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 (hard-hit rate). Up and to the right is better on both. Every dot is a hitter with at least 40 plate appearances this season, and dot size tracks plate appearances. Click any dot to open that hitter's page.

How to read this chart
  • Each dot is his estimate against that hand, with its 50% probable range as the bar. Higher is better.
  • The diamond is his raw rate, which small samples make noisy, so the simulator pulls the dot toward a more trustworthy value.
  • The dashed tick is the league median, and the shaded strip is the middle half of hitters with 50 or more plate appearances.
  • Tap or hover a mark for its number. LHP and RHP are left- and right-handed pitchers. More on the About page

Dot color is estimated bases (EB), what the contact was worth no matter what the defense did with it. Darker means more bases, so a dark hollow ring in the outfield is a crushed ball that got caught.

How to read this chart
Each row is the bases he adds per 100 pitches of that type, on the same scale as the pitcher pages’ “saved/cost per 100” but 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 what that count usually produces. A value of +3.5 means his results against that pitch have been worth about 3.5 extra bases per 100 seen. Higher is better. Types with fewer than 50 pitches seen pool into “Other”.

Deserved vs. actual

Mike Yastrzemski's contact has earned about 8 more bases than he has been credited with. His results have run unlucky so far.

Deserved by his own contact145
Actually credited to him137

Both bars count only his 265 balls in play, so walks and strikeouts are left out.

How to read this chart
Every ball he puts in play is worth the bases its exit velocity, launch angle and direction usually earn. If the second bar is longer than the first, his results have run ahead of his contact and he has been lucky. If it is shorter, he has been unlucky.

How to read this chart
  • Bat speed counts competitive swings only, so bunts and check swings under 50 mph are left out.
  • Swing length is how far the sweet spot of the bat travels during the swing. Attack angle is the bat’s upward or downward tilt through the zone.
  • Swing path tilt is how steep the bat’s path is.
  • None of these is better or worse on its own. Swing style trades power against contact, and the fastest and slowest swings in the league both belong to stars. More on the About page

Timing

He 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. 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 is a swing that is centered, on time and lined up, all at once. On-time swings land within 7 milliseconds of ideal timing. Higher is better on both.
  • Miss distance counts swings and misses only. It is how far the barrel half of the bat passed from the ball, in inches, and lower is better.
  • League comparisons cover hitters with 100 or more tracked swings this season. Switch hitters have both sides combined.

  • This is an overhead view of the batter’s box. The dots are his feet about one second before the pitch, and the rings are the league-average setup.
  • Open means his front foot is pulled off the line to the plate, and closed means it steps toward it. Neither is better or worse.
  • The chart is his monthly average this season. The band and dashed line are the middle half and the median of hitters over the whole season.
