O'Brien was designated for assignment by the Rangers on Saturday.

EDGE Analysis

O'Brien, who has already been with four organizations in 2017, was cast off the Rangers' 40-man roster after struggling mightily in the minors this season (combined .167/.254/.301 with 62 strikeouts in 209 plate appearances). The move was made to make room for Ernesto Frieri. The 26-year-old could draw some interest on waivers given his power potential (combined 122 homer across six minor-league seasons).
