Interesting discussion on this during the Yankee-Giants game today. They mentioned with StatCast, teams have seen HRs are hit at a 26 to 29 degree angle. So players are swinging at that angle.
But they also mention the 26 to 29 degree swing ends up with many strikeouts.
I don't think that the optimal launch angle is really new news.
Wouldn't that be basic artillery information that was known in the 1800s?
