The Cubs designated Nikhazy for assignment Monday.
Nikhazy was a casualty of the Cubs needing to free up a spot on the 40-man roster for the addition of right-hander Yosver Zulueta, who was acquired via trade. A waiver claim by the Cubs in late April, Nikhazy has turned in an 8.44 ERA and 30:21 K:BB over 26.2 innings covering six starts and two relief outings with Triple-A Iowa.
