Magill, who turned 32 years old in November, finishes with a 4.63 ERA and 158 strikeouts in 149 2/3 career major league innings, working mostly in relief. A former 31st-round draft pick, he debuted in 2013 and pitched for the Dodgers, Twins, Reds, and Mariners over parts of five big league seasons.

Magill was released by the Mariners after failing to make their Opening Day roster, but will remain with the organization to open the 2021 season. The 31-year-old righty owns a pedestrian 4.63 ERA, 1.55 WHIP and 158/82 K/BB ratio over 149 2/3 innings at the major-league level since 2013.

Magill needed an arthroscopic debridement procedure on his right shoulder in mid-September, but he is expected to be ready for spring training and will compete for a spot again in the Seattle bullpen. He was a high-leverage guy for the Mariners in 2019 before stumbling to a 6.10 ERA over 10 1/3 innings of relief this year.

Magill earned five saves in 22 total appearances with the Mariners in 2019 before struggling to a 6.10 ERA over 10 1/3 innings of relief in 2020. The 30-year-old required an arthroscopic debridement surgery on his right shoulder in mid-September and was outrighted off the Mariners' 40-man roster earlier this week.
