The Reds designated Richardson for assignment Saturday, Gordon Wittenmyer of The Cincinnati Enquirer reports.

Following the Reds' acquisition of outfielder Dane Myers (knee) from Miami on Saturday, Richardson will end up as the roster casualty necessary to create space on the 40-man. The 25-year-old reliever finished 2025 with a 4.54 ERA, 1.54 WHIP and 30:21 K:BB across 37.2 regular-season innings. However, his 4.06 FIP indicates that he performed slightly better than what his base stats suggest, and there's a chance another team in need of bullpen depth claims the right-hander off waivers.

Tiedemann (elbow) is expected to be fully healthy in time for camp, Keegan Matheson of MLB.com reports.

Tiedemann missed the entire 2025 season after undergoing Tommy John surgery in July of 2024, and he has totaled just 140 innings in the minors since being drafted by Toronto in 2021. Despite that, it was still an easy call for the Blue Jays to add Tiedemann to the 40-man roster in November for Rule 5 protection. While the hard-throwing lefty has flashed high upside and is close to full health, Tiedemann is highly unlikely to handle a big workload in 2026 given all the missed time. "Hopefully he's a factor for us in our rotation," GM Ross Atkins said. "That's the plan, but we would be open to him impacting the team in a bulk role or some creative way, depending on how things are going."

The Athletics designated Waldichuk for assignment Monday.

The move frees up a spot on the 40-man roster for the addition of Jeff McNeil (shoulder), who was acquired via trade. Waldichuk missed all of 2024 and the first half of 2025 while recovering from Tommy John surgery, and he posted an 8.65 ERA, 2.06 WHIP and 64:42 K:BB across 51 innings this past season at Triple-A Las Vegas. The lefty will turn 28 in January and hasn't pitched in the majors since 2023, but with a career 33.9 percent strikeout rate in the minors and team control through 2029, he could draw interest via trade or waivers.

The Rays claimed Bido off waivers from Atlanta on Friday.

Bido has now bounced around via waivers from the Athletics to Atlanta and now to Tampa Bay this month. The right-hander had an unsightly 5.87 ERA and 18.7 percent strikeout rate in 2025, but he was much better in 2024 with a 3.41 ERA and 24.3 percent strikeout rate. Bido does not have minor-league options left, but he offers the flexibility to be used either in a starting or relief role.

Atlanta outrighted Molina to Triple-A Gwinnett on Friday.

Molina was claimed off waivers from the Rockies earlier this month. The 23-year-old right-hander sports an ugly 6.96 ERA, 1.61 WHIP and 65:28 K:BB across 94.1 innings spanning 52 appearances (two starts) over the previous two seasons with Colorado.

The Pirates acquired Montgomery from the Rays on Friday in a three-team trade, Chandler Rome and Ken Rosenthal of The Athletic report.

Montgomery logged a 5.67 ERA and walked 27 over 46 innings with the Rays in 2025, but he also struck out 63 batters and, at 98.7 mph, has one of the hardest average four-seamer velocities in the game. The lefty has past starting experience, but the Pirates are likely to keep Montgomery in the bullpen, and he could work his way into high-leverage appearances.

The Rays acquired Brito and Jacob Melton from the Astros on Friday in a three-team trade that sent Mike Burrows to the Astros and Brandon Lowe, Jake Mangum and Mason Montgomery to the Pirates, Chandler Rome and Ken Rosenthal of The Athletic report.

The 21-year-old right-hander spent the entire 2025 campaign at High-A Asheville and started all 12 games in which he appeared, registering a 3.28 ERA and 11.9 K/9 across 49.1 innings. Brito missed some time with an unspecified injury but was back to full strength in October.

The Astros are acquiring Burrows from the Pirates on Friday in a three-team trade that also includes the Rays, Chandler Rome, Stephen J. Nesbitt and Ken Rosenthal of The Athletic reports.

Burrows opened 2025 in the minors but made his season debut for the Pirates in May, and he delivered a strong rookie campaign with a 3.94 ERA, 1.24 WHIP and 97:31 K:BB across 96 innings. The right-hander is the only piece heading to the Astros in the deal, with Brandon Lowe, Mason Montgomery and Jake Mangum moving to Pittsburgh while the Rays get Anderson Brito and Jacob Melton. Burrows should slot into the middle of Houston's rotation during his sophomore campaign.

The Rays acquired Forret, Slater de Brun, Caden Bodine, Austin Overn and a Competitive Balance Round A pick from the Orioles on Friday in exchange for Shane Baz, Jeff Passan of ESPN.com reports.

Forret began the 2025 season at High-A Aberdeen and finished it at Double-A Chesapeake, holding a sparkling 1.58 ERA, 0.82 WHIP and 91:21 K:BB over 74 innings between the two stops. The right-hander will be heading into his age-22 season and is likely to begin the year at Double-A Montgomery.

The Orioles acquired Baz from the Rays on Friday in exchange for Slater de Brun, Caden Bodine, Michael Forret, Austin Overn and a Competitive Balance Round A pick, Jeff Passan of ESPN.com reports.

Baz had an up-and-down 2025 campaign in his first full season back from Tommy John surgery, finishing with a 4.87 ERA and 176:64 K:BB across 166.1 innings covering 31 starts. However, he had a 5.90 ERA at hitter-friendly George M. Steinbrenner Field, so he should benefit from a move to Camden Yards. Baz is under team control through 2028.
