How to bet them
Fade HRs-allowed overs even in hitter parks — their HR suppression is a skill, not luck. Target hits-allowed overs modestly (grounders have ~.240 BABIP but find holes vs. shifted-out defenses). Fade K overs unless matchup is a high-GB opposing lineup.
Where they fail
Poor infield defense or a shifted-out infield erodes the advantage. Against lift-and-pull lefty lineups at Yankee Stadium, the rare flyballs they do allow leave the yard.
