The Seattle Mariners outrighted three relievers to Triple-A, the team announced. Matt Magill, Carl Edwards Jr. and Nestor Cortes Jr. each elected free agency. The Mariners have seven open spots on their 40-man roster.

Magill underwent arthroscopic debridement surgery on his right shoulder on Sept. 15, effectively ending his season. The surgery was performed by Dr. Neal ElAttrache in Los Angeles, per the team release. The 30-year-old reliever did a fine job for the Mariners in 2019 after Seattle purchased his contract from the Twins in July, posting a 3.63 ERA across 22 appearances totaling 22 1/3 innings. His 2020 was more fraught, however, yielding over six runs per nine innings before going down with injury. Originally drafted in the 31st round by the Dodgers, Magill has appeared in the bigs with the Dodgers, Reds, Twins and Mariners since his debut in 2013.
