The Red Sox traded Hoppe to the Mariners on Tuesday in exchange for minor-league catcher Luke Heyman, Chris Cotillo of MassLive.com reports.

Hoppe spent time with Double-A Portland and Triple-A Worcester in 2025, logging a 4.55 ERA and 1.52 WHIP over 61.1 innings between the two levels. Now with the Mariners, Hoppe will claim a 40-man roster spot and presumably begin the 2026 season at Triple-A Tacoma, where he will be tested in the hitter-friendly Pacific Coast League. Tayler Saucedo was designated for assignment in a corresponding move.

The Diamondbacks designated Henry (elbow) for assignment Tuesday.

Henry is slated to miss most, if not all, of the 2026 campaign after undergoing Tommy John surgery in June. His lengthy expected absence makes it unlikely that another team will be willing to pick him up off waivers, so the D-backs will take the opportunity to remove the injured lefty from their 40-man roster while protecting four prospects from the Rule 5 Draft.

Tampa Bay traded Orze to the Twins on Tuesday for minor-league pitcher Jacob Kisting, Marc Topkin of the Tampa Bay Times reports.

Orze looked pretty good in his first extended run in the majors last season, posting a 3.02 ERA, 1.37 WHIP and 40:19 K:BB over 41.2 innings across 33 appearances. He also picked up three saves and a hold. However, he spent most of the second half of the campaign in the minors after stumbling with the Rays in late June and early July. Orze has a good chance of earning a role in Minnesota's big-league bullpen for 2026, as the club is overhauling most of its relief corps.

The Rockies designated Rolison for assignment Tuesday, Patrick Saunders of The Denver Post reports.

Rolison was a first-round pick (22nd overall) in the 2018 First-Year Player Draft, but he hasn't been able to perform to that pedigree. The lefty had been buried in the minors until last season, when he got into 31 games with Colorado and pitched to an ugly 7.02 ERA and 1.77 WHIP over 42.1 innings. Rolison's 25:20 K:BB paints a pretty clear picture of how much he struggled to get big-league batters out, and the Rockies now appear set to move on.

The Rockies selected Herrera's contract from Double-A Hartford on Tuesday, Patrick Saunders of The Denver Post reports.

Herrera is a lefty hurler who advanced to Double-A for the first time last season. Over 37 relief appearances at that level, he posted a 70:19 K:BB over 46.1 innings along with a 3.69 ERA and 1.30 WHIP. Herrera notched a combined 16 saves between High-A and Double-A in 2025, and the Rockies may be eyeing him as a future closer at the major-league level.

Enright (elbow) was designated for assignment by the Guardians on Tuesday, Zack Meisel of The Athletic reports.

Enright loses his 40-man spot on Rule 5 deadline day after undergoing Tommy John surgery shortly after the end of the 2025 regular season. He will miss all of 2026, but Enright showed real promise before going down with a 2.03 ERA and 1.16 WHIP over 31 innings out of the Cleveland bullpen, numbers which may attract a team on the other end of the competitive spectrum.

The Red Sox traded Bernardino (lat) to Colorado on Tuesday in exchange for Braiden Ward, Patrick Saunders of The Denver Post reports.

Bernardino enjoyed a strong 2025 season with Boston, posting a 3.14 ERA, 1.26 WHIP and 43:26 K:BB over 51.2 innings while notching one save and two holds. The southpaw ended the campaign on the IL due to a strained lat, but there's no reason at this point to think that the injury will affect his availability for the start of spring training. Bernardino should immediately become a key member of a Rockies bullpen that ranked second-to-last in the majors with a 5.18 ERA last year.

Rainey was designated for assignment by the Tigers on Tuesday, Cody Stavenhagen of The Athletic reports.

Rainey's relevance in the fantasy world was fleeting, as he quickly fell off the map after the 2020 season. He has bounced from Washington to Pittsburgh to Detroit in recent years while mostly struggling on the mound. He pitched to an ugly 11.17 ERA and 1.76 WHIP over 9.2 major-league innings in 2025.

The Orioles selected Foster's contract from Triple-A Norfolk on Tuesday.

The 26-year-old was acquired from the Mets in the Gregory Soto trade over the summer, so his addition to the 40-man roster was to be expected. Foster pitched in 13 games for Triple-A Norfolk after the trade and had a 3.38 ERA, 1.38 WHIP and 23:8 K:BB over 16 innings.

The Cardinals designated Alcala for assignment Tuesday, John Denton of MLB.com reports.

Alcala struggled to find his footing on the mound in 2025, finishing the regular season with a 6.22 ERA and 1.75 WHIP across 55 total innings between Minnesota, Boston and St. Louis. He'll have the right to elect free agency if he clears waivers, although he will likely have to settle for a minor-league deal if he does so.
