"We have a few guys struggling out there right now," said White Sox manager Ozzie Guillen with a wry smile. "The way I look at it, yes, I don't think his defense was like it was or is.
"I don't think he takes his glove out there. He's not that type of player," added Guillen of Rios, who is hitting .160 with four RBIs. "He's just taking the wrong routes all the time, the last few games. He'll be fine. I don't worry about him."
Rios was replaced by Brent Lillibridge in center for Sunday's game. Guillen also gave Paul Konerko and Gordon Beckham a rest, with Detroit starter Max Scherzer tough on righties.
