What this means:
The Edge column shows how much better (or worse) this specific
handedness matchup is compared to the batter's overall HR/FB rate. A +40%
edge means the batter's HR/FB rate is 40% higher in this specific L/R split — they mash this type of pitcher.
Look for high-edge batters already ranked in the top 25 for the strongest plays.
B/T = batter hand / pitcher throwing hand.
