🏃‍♂️ Tommy John surgery, a key focus of the book, is named after MLB pitcher Tommy John who was the first professional athlete to successfully undergo the procedure in 1974. ⚾ Author Jeff Passan spent three years traveling across three continents to research youth baseball injuries and interview more than 500 people for this book. 🔬 The ulnar collateral ligament (UCL), which is replaced during Tommy John surgery, naturally has the tensile strength of a fishing line but must withstand forces equal to a person hanging by one arm from a building. 🌟 Dr. Frank Jobe, who pioneered Tommy John surgery, initially gave the procedure only a 1% chance of success, but it now has a success rate of approximately 85%. 📈 The book reveals that nearly 60% of Tommy John surgeries are performed on teenagers, highlighting an alarming trend in youth baseball.
