Barrels/PA
Barrels as a share of plate appearances rather than batted balls.
What Barrels/PA means
The companion to Barrel%. Dividing by batted balls asks "when he hits it, how well?"; dividing by plate appearances asks "how often does damage actually happen?" — so it charges a hitter for strikeouts instead of ignoring them. A high-strikeout slugger can post an elite Barrel% and a merely good Barrels/PA. League median ~5%; 8.5%+ is top-decile.

What counts as a good Barrels/PA
Higher is better — roughly .020 is poor, .050 average, .066 good, and .085 or better elite.
