Goeddel, 29, had a 1.23 ERA and 2.73 FIP in five relief appearances with Seattle, with nine strikeouts and five walks in 7⅓ innings before getting designated for assignment on Wednesday.
The right-hander has a 3.78 career ERA in 115 major league appearances, all in relief, with 118 strikeouts and 43 walks in 112 innings. He pitched four years with the Mets before signing a minor league deal with the Rangers in the offseason. He was released in March and signed a minor league deal with the Mariners, and was called up to the big leagues on May 3.
He was drafted by New York in the 24th round in 2010 out of UCLA.
Goeddel is out of options, having used option seasons in 2014, 2016 and 2017.
To make room on the 40-man roster the Dodgers designated pitcher Henry Owens for assignment. Owens began the season in extended spring training but had yet to pitch for a minor league affiliate this season.
Goeddel will be added to the active roster at some point though it is unclear just when that will be. The Dodgers will need to make a corresponding roster move.
Coincidentally the Dodgers also signed Erik’s brother Tyler Goeddel, a 25-year-old outfielder, this week to a minor league deal and Tyler made his debut with Double-A Tulsa on Thursday.
