Bolanos (ribs) will remain on the Royals' 30-man roster, Lynn Worthy of The Kansas City Star reports.
Bolanos was initially set to join the taxi squad after right-hander Brady Singer was activated Saturday, but the Royals chose to option catcher Meibrys Viloria instead. Although Bolanos will remain on the active roster, he's unlikely to be used in high-leverage situations out of the bullpen.
