The Rangers designated Castellanos for assignment Wednesday, Anthony Andro of FOXSportsSouthwest.com reports.

Analysis:

To make room on the 40-man roster for right-hander Joe Saunders, who was signed to compete for a rotation spot, the Rangers decided to give Castellanos the boot. Castellanos has hit just .171/.186/.390 in a brief sample at the major league level, but has shown good pop and speed in the minors. He could join his fourth different team since October if taken off waivers.
