Rest-of-Season Projections
Signed a one-year, minor-league contract with the Mariners in April of 2025.
Removed from 40-man roster
The Mariners designated Pop for assignment Saturday, Tim Booth of The Seattle Times reports.
Analysis
The move makes room on Seattle's 40-man roster for Juan Burgos, whose contract was selected from Triple-A Tacoma. Pop was promoted to the majors in mid-June, and after allowing only one run over his first three outings, he was roughed up for eight runs (seven earned) against the Twins on Thursday.
