Dr. Lewis Yocum's famous baseball patients

Dr. Lewis Yocum — one of baseball's most respected arm doctors — has died after a secretive battle with cancer. He was 66. Yocum was a protege of Frank Jobe (who performed the first Tommy John surgery). Along with Dr. James Andrews, Yocum was one of the two orthopedic surgeons that baseball players turn to when they're facing arm issues. Yocum was also the team doctor for the Los Angeles Angels. The team recently renamed its training room in his honor.

Here are some of Yocum's most famous patients.
