The big question is: Can the Royals afford to send Bonifacio down if he keeps hitting?
"It just depends," Yost said. "If Boni continues to swing the bat the way he has, we'll see. We've got a week."
The Royals are carrying eight relievers, and in theory, one could be shuttled back to Omaha to make room for Soler. But even then, finding playing time for both Bonifacio and Soler would be challenging in an outfield that already includes Lorenzo Cain and Alex Gordon.
It is possible that Yost could platoon Bonifacio or Soler at designated hitter with the left-handed hitting Brandon Moss.
Then again, do the Royals even want to carry a developing player such as Bonifacio, 23, -- who is the club's No. 11 prospect per MLBPipeline.com -- on the roster if he isn't guaranteed at-bats on a consistent basis?
"I don't know," Yost said. "We just started all those discussions today."
This could be a critical week ahead for Bonifacio as he tries to prove he deserves to stay on the 25-man roster, but not according to Yost.
"It doesn't make it a critical stretch for him," Yost said. "It works out, one way or another."
