Exit velocity drives the outcome now, so a positive gap = out-hit his contact quality (lucky); negative = unlucky.

Red = elite, blue = poor. Hitting bars rank batted-ball quality; pitching bars rank contact suppressed (so a low EV-against or Barrel% is elite). Cuts are calibrated to O27's exit-velocity distribution, not MLB's.
