The Mariners designated Elias for assignment Monday.
Elias and fellow bullpen arm Sergio Romo both lost their spots on the 40-man roster with Seattle needing to reduce its pitching staff to 13 men ahead of Monday's MLB-imposed deadline while also needing to clear a spot for reliever Ken Giles (finger) to come off the 60-day injured list. Following his promotion from Triple-A Tacoma on May 27, Elias made six appearances out of the bullpen and gave up two earned runs on six hits and a walk while striking out six in 6.2 innings.
