While reliever Garrett Richards has reached free agency after granting a waiver,
It is unclear if Hurler was released by the Rangers.
His return came after Texas named him for the assignment last week.
Richards, 34, signed a one-year guarantee with Texas in the off-season.
He was transferred to the bullpen in the middle of last season with the Red Sox.
Always a hard thrower, Richards averaged a solid 94.4 MPH on his fastball
and 88.6 MPH on a slider that has been his primary offering this season.
He has generated swinging strike on a good 12.1% of his total pitches.
Richards generally leaves a fair amount of tough contact.
Even with a 52.6% ground-ball rate,
He hasn't managed to keep consistent runs off the board at Arlington.
