Batting average is the worst metric in baseball for measuring development.

A hitter can go 0-for-4 and have four quality at-bats.

Another can go 2-for-4 and have given away both outs on first-pitch ground balls.

Average rewards luck. QAB% rewards process.

That's why every player I work with tracks QAB%, not average. It's the approach, the way they think and handle each at-bat, that tells us whether the work is showing up between the lines.

A Quality At-Bat counts when the hitter does at least one of the following:

  • Hits the ball hard (line drive, deep fly, gap)
  • Drives in a run with two outs
  • Sees six or more pitches and doesn't strike out
  • Walks / gets hit by a pitch
  • Moves a runner over in a much-needed situation
  • Battles to a full count and doesn't strike out
  • Executes a sacrifice (bunt or fly)
  • Beats out an infield hit by hustling out of the box

And many more.

What QAB% tells you:

  • Is the hitter competing every at-bat or only when it feels good?
  • Is the approach holding up against off-speed and two-strike counts?
  • Is the player a producer in pressure situations or a passenger?

If a hitter can go up with the focus to produce quality at-bats, the results catch up. Always.
