Giles underwent Tommy John surgery in October, so he isn't likely to make a big impact in the 2021 campaign. In his last full healthy season in 2019, Giles was dominant with the Blue Jays by racking up 23 saves to go along with 83 strikeouts across 53 innings. While he could eventually factor into the saves picture for the Mariners in 2022, he will be 31 years old and coming off major arm surgery.
