Kivlehan hit just .184 with 17 runs, eight doubles, one home run and 16 RBIs in 141 at-bats for Triple-A Round Rock this season before he was designated for assignment last week to open a spot on the Rangers' 40-man roster. He was ranked as Texas' 24th-best prospect by MLBPipeline.com.
Kivlehan is expected to report to Triple-A Tacoma, where the Rainiers will need to make a roster move to clear a spot for him.
While with the Mariners, the former Rutgers defensive back hit .288/.352/.481 with 70 home runs and 318 RBIs in four Minor League seasons, including .256 with 22 homers and 73 RBIs last year in his first full season in Tacoma.
Scribner, 30, has spent the entire season on the 15-day disabled list since being sidelined early in Spring Training with a strained right lat muscle. He was 2-2 with a 4.35 ERA in 54 appearances for the A's last year before joining the Mariners in a December trade for right-hander Trey Cochran-Gill.
