Royals' Will Smith: Placed on IL with back spasms

The Royals placed Smith on the 15-day injured list Monday with low-back spasms.

Smith had been bludgeoned for 14 runs over 4.2 innings cover his last five appearances. It's not clear how long he might be sidelined. Carlos Hernandez was recalled from Triple-A Omaha to take Smith's spot on the active roster and in the bullpen.
