Tommy John Anniversary Future

FILE - Dr. Jeffrey Dugas examines Sammy Rosenfield, of Grafton, Mass., at the Andrews Sports Medicine & Orthopaedic Center in Birmingham, Ala., April 5, 2017. Tommy John surgery, like baseball itself, is evolving to increase success and sometimes speed return. Dugas developed a procedure that cut recovery time to as little as nine months for some pitchers with torn elbow ligaments. He envisions more innovations within five-to-seven years.
