The Rangers released left-hander Miguel De Los Santos, according to the team’s website. The move comes six days after the team removed the De Los Santos from its 40-man roster and designated him for assignment.
The 24-year-old posted a 5.22 ERA with 10.7 K/9 and 5.2 BB/9 in 58 2/3 innings at Double-A this year. He started four games for the Frisco RoughRiders and pitched out of the bullpen in 22 others. Baseball America ranked De Los Santos 29th among Rangers prospects before the season, crediting him for the best changeup in the organization.
