To make room for RHP Santiago Casilla, the Oakland A’s have designated reliever Kiko Calero for assignment.
The 33-year old Calero began the season on the disabled list with a torn rotator cuff and finally returned on May 30th. Since then, the righty reliever was used very sparingly, only pitching 4 2/3 innings in five appearances in 2008 and had a 3.86 ERA over this span. Last year, Calero’s season ended in early September due to the rotator cuff injury and he had also missed three weeks in July with a sore shoulder.
Oakland now has ten days to waive, trade, or release him.
