Wednesday saw the return of Jonathan Sanchez to the rotation, following more than a month on the disabled list with left biceps tendinitis. Yost said that with Sanchez's return, the rotation would now have a more consistent look for the foreseeable future.
Following Sanchez's start, it will be Luke Hochevar in Thursday's series finale against the Brewers. Then Vin Mazzaro, Bruce Chen and Luis Mendoza will pitch the three games in St. Louis against the Cardinals.
The starting staff has been ravaged by injuries this season. In addition to Sanchez, Felipe Paulino is currently spending his second stay of the year on the disabled list with a right groin strain. Danny Duffy will undergo Tommy John surgery and miss the remainder of the season. Nate Adcock, Everett Teaford and Will Smith have also made spot starts for the Royals this season.
