Holland, who has 32 saves and a 3.83 ERA, was not available to comment after Yost revealed the news. Holland had held the closer role since midway through the 2012 season.
Yost also said Holland will rest a few days because of tightness in his right elbow.
"He's been battling with it all year," Yost said of Holland's elbow soreness. "He's got 30-something saves and he's dealing with it. You manage it."
"Pretty much going to go with Wade," Yost said.
