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.

The Marlins and Garrett (elbow) avoided arbitration by agreeing to a one-year, $1.53 million contract Thursday, Fish on First reports.

Garrett will receive the same salary for a second straight year after he missed all of the 2025 season following UCL revision surgery with an internal brace on his left elbow. The southpaw is a little over a year removed from the operation and it's unclear whether he will be ready in time for Opening Day.

The Cardinals and Liberatore avoided arbitration by agreeing to a one-year, $2.26 million contract Thursday, Derrick Goold of the St. Louis Post-Dispatch reports.

Liberatore was eligible for salary arbitration for the first time as a Super 2 qualifier. The left-hander had a solid first full season in the Cardinals' rotation, finishing 2025 with a 4.21 ERA, 1.31 WHIP and 122:40 K:BB in 151.2 innings over 29 starts. Liberatore will be counted on as a key member of the St. Louis rotation again in 2026.

The Nationals and Irvin avoided arbitration by agreeing to a one-year, $2.8 million contract Thursday, Andrew Golden of The Washington Post reports.

Irvin finished the 2025 campaign with a 5.70 ERA while serving up a major-league high 38 home runs. The right-hander's durability has been his biggest asset to this point, as he's made 33 starts in consecutive seasons. Irvin does not appear locked into a rotation spot in 2026, though his chances of nabbing one would increase if the Nationals trade MacKenzie Gore.

The Nationals and Gore avoided arbitration by agreeing to a one-year, $5.6 million contract Thursday, Robert Murray of FanSided.com reports.

Gore concluded the 2025 campaign with a 4.17 ERA, 1.35 WHIP and 185:64 K:BB over 159.2 innings covering 30 starts. The left-hander's name has come up often in trade rumors this offseason, and he will be eligible for salary arbitration for a final time next winter.

Atlanta claimed Waldichuk off waivers from the Athletics on Thursday.

Waldichuk was sidelined for a year-and-a-half following Tommy John surgery and posted an 8.65 ERA, 2.06 WHIP and 64:42 K:BB across 51 innings with Triple-A Las Vegas in 2025 after returning. The lefty boasts a career 33.9 percent strikeout rate in the minors and has minor-league options remaining, so it's not a surprise he didn't pass through waivers. Waldichuk will likely begin 2026 in the Triple-A Gwinnett rotation.

The Cubs and Steele (elbow) avoided arbitration by agreeing to a one-year, $6.775 million contract Thursday, Patrick Mooney of The Athletic reports.

Steele gets a modest raise after he missed nearly all of the 2025 season following UCL revision surgery. The left-hander's rehab has come along well, but he is expected to be sidelined for at least the first month or so of the 2026 campaign.

The Mets and Peterson avoided arbitration by agreeing to a one-year, $8.1 million contract Thursday, Joel Sherman of the New York Post reports.

It's a nice bump in pay for Peterson, who had been eligible for arbitration for the final time. The lefty faded down the stretch for the Mets in 2025 but still finished with a solid 4.22 ERA and 150:65 K:BB over 168.2 innings covering 30 starts.

The Rockies and Feltner (shoulder) avoided arbitration by agreeing to a one-year, $2.45 million contract Thursday, Ari Alexander of 7 News Boston reports.

Feltner finished the 2025 season on the minor-league injured list with right shoulder inflammation, and he had also previously missed time with back trouble. It's unclear whether he will have any limitation when reporting to spring training next month. Feltner had been eligible for arbitration for the second time.
