"Out of precaution, we wanted to give [Hochevar] the day [off], and we'll see how he feels tomorrow," Yost said. "We weren't going to use him today."
Yost said Hochevar, one of the Royals' valuable setup men, who missed all of 2014 because of Tommy John surgery, felt the tightness in the elbow after his one-inning, two-walk appearance in Friday night's 1-0 loss in the series opener.
Yost did not seem to think that it was anything more than a day-to-day situation.
