Major League Baseball and USA Baseball, have teamed up to create new guidelines to help young arms stay intact.
They have created Pitchsmart.org at a time when major league elbows are wearing out at record rates, with Tommy John surgeries nearly doubling over the past three seasons. This spring pitchers Yu Darvish of the Rangers and Zack Wheeler of the Mets were the latest to have it.
"There is a real sense of urgency to understand the entire TJ surgery now," said Stan Conte, the Dodgers' vice president of medical services.
In July, the American Sports Medicine Institute went so far as to describe it as an epidemic and wrote: "In many cases, the injury leading to Tommy John surgery began while they were adolescent amateurs."
