50+ games in and it appears that yet again, MLB has secretly changed the baseball. Hard hit balls, barrels, and exit velocity percentages are all up from last year yet HR’s are down over 25%.
Maybe it’s an attempt to keep soaring batter contracts down, maybe it’s their gambling partners making more money on HR props than pitching ones, maybe it’s a quality issue at the Rawlings facility in Costa Rica. Maybe these are all just tinfoil and MLB is still tweaking things to find their ideal new baseball.
