Berroa, the AL Rookie of the Year last season, missed Friday
night's 9-7 loss at Minnesota with flulike symptoms.
"We ran some tests, including (a spinal tap) and the doctor
recommended we rest him," manager Tony Pena said.
Berroa, who hit .287 with 17 homers and 73 RBIs last year, is
hitting .296 (8-for-27) with one homer.
Appier was scheduled to start Saturday for the first time since
Aug. 26. During the offseason, Appier had surgery to repair a
flexor tendon tear in his right elbow.
Kansas City also purchased the contract of shortstop Andres Blanco from Double-A Wichita and sent left-hander Jaime Cerda to Triple-A Omaha.
Right-hander Miguel Asencio was moved from the 15- to the 60-day
DL to make room on the 40-man roster.
Blanco was in the starting lineup against Minnesota, batting
ninth, as the Royals tried to snap a four-game losing streak.
The 20-year-old from Carabobo, Venezuela, was hitting .292 over
the first eight games with Wichita. He hit .244 with 61 runs and 25
RBIs in 113 games for Class-A Wilmington last year.
