The Red Sox acquired left-handed reliever Danny Rosenbaum last year in exchange for minor league catcher Daniel Butler. As he rose through the minors, the former 22nd round draft pick looked to have a nice career ahead of him as a left-handed specialist.
But then, Rosenbaum got news that would make any pitcher cringe. He would have to decide between giving up his baseball career, or have a procedure known as Tommy John surgery. The procedure involves replacing the damaged ulnar collateral ligament in the elbow with a tendon from either the knee or hamstring.
