I've been to a few of my son's Fall scrimmages, and there's no doubt the new baseball is carrying much further. 247-son plays in a relatively large "Pitchers" college ballpark and there hasn't been many dingers hit there since the new BBCOR bats were implemented. I know it's early on, but I'd estimate the HR totals this Fall to have increased 3-4 times compared to the past three Fall seasons.
My son, a RHP, actually likes the new balls. Yes, he's given up two long balls this Fall, but he feels like he has more movement on his Change/Fastball. I'm curious to see what the actual results will be when the regular season begins in February.
