KANSAS CITY -- The injury-plagued Royals took another blow on Friday when center fielder David DeJesus was placed on the 15-day disabled list with a strained left hamstring.
To fill the roster void, Kansas City brought up right-hander Joe Nelson from Triple-A Omaha. Nelson
was 1-0 with a 1.04 ERA in five relief appearances at Omaha. The Royals got Nelson on the 40-man roster by transferring Mike MacDougal from the 15-day to the 60-day DL.
"He has been low in the strike zone with his fastball and he has an out pitch with his changeup," general manager Allard Baird said of Nelson. "He has worked hard on the command of his fastball."
DeJesus suffered the strained hamstring last Wednesday in Chicago while running out an infield grounder. Shane Costa will be the regular center fielder while DeJesus is out and Esteban German can also help fill that void.
"It's frustrating, but I just want to get better as soon as possible," DeJesus said.
The Royals, who placed right-hander Denny Bautista on the disabled list last Sunday, retroactive to April 14, are now facing the possibility that Bautista could miss up to four weeks because of a small tear in his right pectoral muscle.
Right-hander Runelvys Hernandez could possibly be summoned to bolster the starting rotation, but manager Buddy Bell said that decision has not been made.
"There is a chance that he might make his next start up here, but we don't know that yet," Bell said.
