According to Cotillo, the deal does not guarantee Blanks a spot on the team's 40-man roster, but the 28-year-old "has a good shot" to make the team if he stays healthy through the end of spring training.
Blanks was designated for assignment by the Oakland Athletics on Nov. 28. He was traded to Oakland by the San Diego Padres in May and played 26 games in 2014, hitting .309 with a .409 on-base percentage, two home runs and seven RBIs.
Blanks has never played more than 88 games in a single season and has been limited by several injuries in his career. He made his MLB debut with the Padres in 2009 and hit .228 with 28 home runs and 98 RBIs in 715 career at-bats with them.
The Rangers finished an American League-worst 67-95 last season.
