In MLB, hitters are mostly right-handed , with left-handed hitters making up about a quarter of hitters and switch-hitters about 10%. That puts right-handed hitters at roughly 65% and left-handed hitters at roughly 25% , with the exact count changing by season and roster size.

Quick scoop

  • Right-handed hitters: about 65%.
  • Left-handed hitters: about 25%.
  • Switch-hitters: about 10%.

Why it varies

The total number of MLB hitters changes every year because rosters, call-ups, injuries, and platoon usage all shift the mix. So the cleanest answer is usually given as a percentage , not a fixed headcount.

Bottom line

If you just want the simple split, MLB hitters are roughly 2 right-handed for every 1 left-handed , plus a smaller switch-hitting group.
