The Mariners designated starter Jeremy Bonderman for assignment, according to a team press release. They also recalled lefty Lucas Luetge.

Bonderman, 30, had his contract purchased by the Mariners in June, at which point he made his first MLB start since October 2010. After 63 2/3 lackluster Triple-A innings, Bonderman posted a 4.93 ERA, 3.8 K/9, 4.0 BB/9, 0.94 HR/9, and 42.5% groundball rate in seven starts for Seattle. Bonderman had elbow surgery in April 2012 and signed a minor league deal with his home-state Mariners in December of that year.

Bonderman was drafted 26th overall by the Athletics out of high school in '01, and was quickly traded to the Tigers as the player to be named later in the deal that sent Carlos Pena to Detroit, Ted Lilly to the Athletics, and Jeff Weaver to the Yankees. After just 27 minor league starts, Bonderman debuted for the Tigers in '03 at age 20. He had an upward trajectory until shoulder surgery derailed his career.
