Perez's contract was selected by the Cubs on Tuesday.

EDGE Analysis

Perez spent the start of the season at alternate camp, but he'll join the 40-man roster and major-league club to take the place of Steven Souza (hamstring) on the active roster. Southpaw Brad Wieck (knee/hamstring) was transferred to the 45-day injured list to clear space on the 40-man roster. Perez should fill a depth role for the Cubs.
