Palacios is not in the lineup for Friday's contest versus the Padres.
Padres starting pitcher Casey Mize has reverse splits, as the right-hander has held lefties to a .564 OPS while righties have posted a .768 OPS. That explains why the lefty-swinging Palacios is sitting out in favor of righty Jorge Mateo, who will slot in at second base for the Rays.
