"If you watch Mondi in batting practice, when he's done taking ground balls, he goes out and shags balls in center field," Yost said. "He's very athletic and looks natural out there. Could he do that? Yeah.
"It's been mentioned. But have we talked about it [in terms of planning]? No. I'm already thinking of Spring Training and he will play some short, some second, some outfield.
"The same with [Ramon Torres]. He's athletic with a strong arm. It's that versatility that can't hurt you."
The Royals may have to plan a future without pending free agent Lorenzo Cain in center field.
"But we haven't talked about Mondi full-time in center," Yost said. "... Because of his arm and athleticism, he could play anywhere."
Yost pointed out that even if the Royals don't re-sign Cain, they still have Paulo Orlando as an option in center field in 2018.
