Atlanta designated Waldichuk for assignment Saturday.

Just two days after being claimed off waivers from the Athletics on Thursday, Waldichuk will once again enter the waiver process following Atlanta's addition of Tyler Kinley on Saturday. After missing the entire 2024 campaign while recovering from Tommy John surgery, the 28-year-old southpaw returned to action at Triple-A but struggled to the tune of an 8.65 ERA and 2.06 WHIP across 51 innings.

The Rockies traded Grosz to the Diamondbacks on Saturday in exchange for Jake McCarthy

Grosz spent all of 2025 at the High-A level, posting a 4.67 ERA and 1.30 WHIP across 125.1 innings between the Yankees' and Rockies' affiliates. The 23-year-old righty will likely aim to reach Double-A at some point in 2026.

Nelson and the Diamondbacks agreed to a one-year, $3 million contract to avoid arbitration Thursday, Jack Sommers of DBacks on SI.com reports.

Nelson was arbitration eligible for the first time and is set for a $2.2 million raise from last season. He posted career-best results in 2025 and is poised to be a key member of Arizona's rotation for the upcoming campaign.

Cabrera agreed to a one-year, $4.45 million contract with the Cubs on Thursday to avoid arbitration, Jesse Rogers of ESPN.com reports.

Cabrera put together a strong 2025 campaign with Miami, finishing with an 8-7 record (26 starts) while posting a 3.53 ERA, 1.23 WHIP and 150:48 K:BB across 137.2 innings. He was traded by the Marlins to the Cubs on Wednesday, and if healthy, he provides the Cubs with upside and strikeout potential out of the rotation.

Sears signed a one-year contract with the Padres on Thursday to avoid arbitration.

Sears was a regular part of the Athletics' rotation before being shipped to the Padres in late July, after which point he was sent back and forth between Triple-A and the majors. He ended the 2025 regular season with a 5.04 ERA and 1.32 WHIP -- both career worsts -- across 135.2 innings, and his spot in the Padres' rotation could be shaky if he gets off to a slow start in 2026.

Miller signed a one-year, $4 million contract with the Padres on Thursday to avoid arbitration.

It's a nice raise for Miller in his first season of arbitration eligibility. The right-hander opened 2025 with the Athletics before being traded to the Padres in July, and between both teams he posted a 2.63 ERA, 0.91 WHIP, 10 holds, 22 saves (out of 26 opportunities) and a 104:28 K:BB across 61.2 regular-season innings. Miller served as more of a setup man for the Padres after being the Athletics' top closer. However, with Robert Suarez signing with Atlanta during the offseason, Miller figures to step in as San Diego's closer for the 2026 campaign.

Meyer (hip) and the Marlins agreed to a one-year contract to avoid arbitration Thursday, Isaac Azout of FishOnFirst.com reports.

Meyer has struggled with injuries throughout his big-league career and made only 12 starts in 2025. He posted a 4.73 ERA and 68:20 K:BB across 64.2 frames before being sidelined in early July by a hip issue that required surgery. Meyer figures to be ready for spring training and should have the inside track on a rotation spot to begin 2026.

Lodolo signed a one-year, $4.725 million contract with the Reds on Thursday to avoid arbitration, Mark Feinsand of MLB.com reports.

The deal also includes up to $450,000 in incentives, per Gordon Wittenmyer of The Cincinnati Enquirer. Lodolo spent the majority of 2025 in the Reds' rotation before being moved to the bullpen for one late-season appearance, plus Cincinnati's brief playoff run. He ended the regular season with a 9-8 record (over a career-high 28 starts) while posting a 3.33 ERA, 1.08 WHIP and 156:31 K:BB across 156.2 innings. Lodolo has seen his ERA and WHIP numbers steadily improve over the past three seasons, and his 4.8 percent walk rate in 2025 ranked fourth among starters with at least 150 innings.

Singer agreed to a one-year, $12.75 million contract with the Reds on Thursday to avoid arbitration, Mark Feinsand of MLB.com reports.

Singer finished his first year in Cincinnati with a 4.03 ERA and 1.24 WHIP alongside a 163:60 K:BB across 169.2 regular-season innings, and he'll now be rewarded in the form of a $4 million salary increase. He'll presumably claim a spot at the back end of the Reds' rotation to begin 2026 and is slated to become a free agent after the end of the season.

Weathers agreed to a one-year contract worth $1.35 million with the Marlins on Thursday to avoid arbitration, Isaac Azout of FishOnFirst.com reports.

Weathers opened the 2025 campaign on the Marlins' injured list due to a forearm strain, but after debuting in mid-May he wound up back on the IL with a lat strain after just five starts. The 26-year-old southpaw was cleared to return in September, and over his last three outings of the season he posted a 1-1 record with a 5.27 ERA, 1.68 WHIP and 14:4 K:BB across 13.2 innings. Weathers has started in only 39 major-league games over the last three seasons, but if he remains healthy, he should serve in a prominent role in the Marlins' rotation in 2026.
