Pirates' Angel Perdomo: Recently had Tommy John surgery

Perdomo underwent Tommy John surgery on his left elbow Oct. 6, Jason Mackey of the Pittsburgh Post-Gazette reports.

It came as a bit of a surprise when it was announced Thursday that the Pirates placed Perdomo on waivers, but now we know why the move was made. He'll be out until 2025 and should also clear waivers, at which point he can be outrighted.
