During the White Sox Opening Day intros, they just introduced Mark Salas as the team's bullpen catcher. No idea if it is THE Mark Salas.
I'm going to go out on a limb and say it is.
What is the restricted list?
Didn't Romero get busted for PEDs or something in the off-season?
Ah yes. That is correct.
