Royals manager Mike Matheny said Bubic will start Friday's game against the Tigers, Lynn Worthy of The Kansas City Star reports.
Bubic opened the second half in a bullpen role for Kansas City, but he'll reclaim a spot in the rotation after the Royals placed Danny Duffy (forearm) and Brady Singer (shoulder) on the injured list Tuesday. After Singer lasted only two innings in his most recent start Saturday, Bubic impressed in long relief, giving up one run on two hits and three walks while striking out five in six frames. Bubic is thus sufficiently stretched out to handle a starter's workload as he slots back into the rotation.
