The Mariners have signed right-hander Zach Pop to a minor league contract after he was designated for assignment by the Blue Jays due to elbow inflammation. The 28-year-old, who has a career 4.45 ERA and was a seventh-round pick in 2017, struggled in the 2024 season with a 5.59 ERA but showed potential with a new cutter. With a fast sinker and a strong slider, the Mariners hope to help Pop refine his skills and develop into a reliable bullpen arm.
