I am an umpire and have coached for 20+ years. I have also purchased 50 or more bats in the last 18 years for my kids--and still have most of the receipts (hidden from my wife)! They pop off all the time. Maybe your experience with a bat is from behind the plate? Ask any parent of a kid who has played Tee Ball through high school who has shelled out $$$ on bats (aluminum, composite, half and half, BBCOR, etc.) and they will tell you bats either cracked or had the end caps pop off. Little league kids would go through two or three bats a season (non BBCOR) because of one of the aforementioned issues. Perhaps the new USA Baseball stamped bats will be different but I highly doubt it! Can't fix a cracked bat but you can certainly put the end cap back on!
