Vargas (appendix) is expected to throw a bullpen session Wednesday, Andy McCullough of the Kansas City Star reports.

Analysis:

Vargas was able to play catch from 110 feet Saturday and will likely take part in two or three bullpen sessions before returning to action. The Royals have patched the rotation with Bruce Chen in the meantime, but he'll slide back into a long-relief role once Vargas is deemed ready to go.
