Pop

The details are not yet known, but we do know that the deal is a major league one. Pop only pitched 6 2/3 innings in the big leagues last year, but he allowed 11 earned runs on 15 hits. In his career, he has a 4.88 ERA, 1.36 WHIP, and 126/55 K/BB ratio in 162 1/3 innings out of the bullpen.

Pop fortifies Chicago’s relief corps after making five relief appearances earlier this season between the Mariners and Mets. The 28-year-old righty has compiled a serviceable 4.88 ERA across 162 1/3 innings (163 appearances) in the big leagues dating back to 2021. He’ll head to Triple-A Iowa as emergency organizational depth.

Pop was designated for assignment after just one appearance with the Mets where he gave up three runs over 1 1/3 innings. He’ll likely be looking at a minor league deal with whatever team he signs with.

Pop, who is out of options, gave up three runs in 1 1/3 innings in his lone appearance for the Mets. If he clears waivers, the Mets might attempt to re-sign him to a minor league deal.

Pop augments New York’s bullpen depth ahead of Saturday’s showdown against the Yankees after struggling in four relief outings earlier this season for the Mariners. He’s made 162 appearances in the big leagues dating back to 2021. The 28-year-old righty represents a reclamation project for the Mets’ pitching development engine at this stage of his career.

The 28-year-old hurler elected free agency from the Mariners on Wednesday afternoon and it didn’t take him long to land on his feet elsewhere. Pop had registered a 13.50 ERA, 2.25 WHIP and a 3/2 K/BB ratio across 5 1/3 innings in the big leagues with the M’s this season. Expect the move to be made official on Friday.

Pop could return to Seattle on a minor-league deal, but he’ll at least test the waters after he was designated for assignment by the Mariners on Saturday.

The 28-year-old hurler made just four appearances with the Mariners, posting a 13.50 ERA, 2.25 WHIP and a 3/2 K/BB ratio over 5 1/3 innings. He has had success at the big league level in the past though, which may be enough for another team to take a chance on him on waivers.

He’ll take the place of Logan Evans on the Mariners’ active roster. Pop, who was signed to a minor league deal after he was released by the Blue Jays at the beginning of April, posted a 2.79 ERA, 1.14 WHIP and a 9/5 K/BB ratio over 9 2/3 innings in 11 appearances in the minor leagues this season. He’ll function in a middle relief role for the M’s.

Pop was released by the Blue Jays at the start of April. The 28-year-old has had some success in the majors, but has struggled over the last two seasons. Seattle’s bullpen has struggled in 2025, so they’ll look and see if they can turn him into something useful for a very low price.
