Now, however, Yost said he is scrapping the notion of those built-in days off.
"Just not going to happen," Yost said.
"I talked to my staff and decided that's not what we want to do," Yost said. "We'll pick spots and give Sal a day off. We'll look for days -- a Saturday off or a Sunday. We just decided to go that way."
Yost said it will be up to him and his staff to assure that Perez gets his necessary rest.
"You got so many off-days early in the season," Yost said. "[The rest] comes into play about June, July and August. But then in September, that's it [for days off] unless we have a big lead."
