Athletics' Ken Waldichuk: Undergoes Tommy John surgery

Waldichuk underwent Tommy John surgery on his left elbow Wednesday, Martin Gallegos of MLB.com reports.

Waldichuk was initially diagnosed with a UCL tear last October. He opted for a minor procedure on his elbow last fall in hopes of avoiding the surgery he eventually had Wednesday. The left-hander figures to be sidelined until around midseason of 2025.
