The 20 Biggest Tech Advancements in Sports History

Tommy John Surgery

Year Introduced: 1974
Sport: Baseball

First performed by Dr. Frank Jobe, Tommy John Surgery has been revolutionary in lengthening the shelf-life for a pitcher's career, giving surgeons the ability to switch out crucial tendons in a player's arm for healthier ones from other parts of the body, such as the hips or knees. Up-and-coming flamethrower, Stephen Strasburg, is just one of the many pitchers who has successfully returned from the procedure, along with former All-Stars like Chris Carpenter and Eric Gagne.
