First of all, that a paragaph in that article is fundamentaly wrong: "Ash bats tend to crack innocuously, the study found, while maple bats explode, sending huge chunks of wood in every direction."
Maple will tend to break along a line and usually produce two pieces, Ash on the other hand tends to "splinter" or "explode" at the point of break.
Personal story here too, I was at an Astros V. Cardinals game about 4 or 5 years ago. Sitting fifth row behind Cardinals dugout. Edgar Rentaria got sawed off and the barrel of his bat came hurling towards me and two of my friends. We all saw the bat coming and ducked out of the way, it hit the seat next to one of my friends, which was empty, he grabbed the bat, just the barrel, and still has it to this day. What kind of bat was it?
It was a Louisville Slugger c243 Ash bat
The only difference between our story and the story in the article... we were paying attention.
About a minute later we all got calls from our other friends telling us they saw us on TV.
