The New York Yankees rotation depth is about to be tested. Pitcher Chase Whitley will have season-ending Tommy John surgery Tuesday, according to Ken Rosenthal of FoxSports.com.
The news doesn't come as a huge surprise. Whitley left his last start with elbow discomfort, and an MRI revealed a partial tear of his UCL. Whitley received a second opinion, but ultimately decided to have surgery over attempting to rehab the injury.
Once Whitley has the surgery, he'll join ace Masahiro Tanaka on the disabled list. Tanaka is also dealing with a tear in his UCL, but opted for the rehab route.
