Rest-of-Season Projections
Selected to MLB roster
The Mariners selected Pop's contract from Triple-A Tacoma on Friday.
ANALYSIS
After signing a minor-league deal with Seattle in April, Pop began his tenure in the organization in rookie ball but joined the Triple-A club in late May, and at that level he owns a 3.52 ERA and 1.25 WHIP in 7.2 innings. He'll now join the big-league squad to give the Mariners some extra bullpen depth and will likely be limited to low-leverage situations after posting a 5.81 ERA in the majors across the past two seasons. Logan Evans was optioned to Tacoma in a corresponding move.
