While the surgery has become more common – even among college, high school and unfortunately, even middle school players – I wouldn't say it's an epidemic. I would say it's more a matter of the chickens coming home to roost. Athletes are playing baseball at younger and younger ages, with many playing year-round.
I don't agree with people who say don't worry because the kids are young and they'll be fine. I'm like a bean counter when it comes to pitching. Each pitch, each throw equals one click. Injuries result as generalized wear and tear on the arm.
