The Mariners claimed Mattson off waivers from the Pirates on Monday, Colin Beazley of the Pittsburgh Post-Gazette reports.

Mattson posted a 2.45 ERA and 45:19 K:BB over 47.2 innings in 2025, but he stumbled in 2026 with a 5.35 ERA and 36:18 K:BB over 38.2 frames. The 31-year-old will look to fill a middle relief role in Seattle.

The Marlins claimed Weston off waivers from the Mets on Monday, Will Sammon of The Athletic reports.

Weston made one scoreless appearance in 2026 with the Orioles in what was his major-league debut. The 26-year-old had a 7.18 ERA across 57.2 frames at the Triple-A level this season, though that came with 76 strikeouts.

The Cardinals re-signed Fleming to a minor-league contract Monday, Derrick Goold of the St. Louis Post-Dispatch reports.

Fleming made one appearance with the Blue Jays in 2026 but otherwise spent the season at the Triple-A level in three different organizations. The southpaw held a 4.01 ERA and 82:24 K:BB over 112.1 innings during his time on the farm, and he'll give St. Louis some experienced rotation depth at Triple-A Memphis.

The Cubs re-signed Webb to a one-year, $2 million contract with a $4 million club option (or $500,000 buyout) for 2028 on Monday, Robert Murray of FanSided.com reports.

Though he was miscast as a high-leverage reliever, Webb provided the Cubs with some good work in 2026, posting a 3.36 ERA and 73:25 K:BB over 67 innings while notching nine saves. He could fill more of a middle relief role in 2027 if the Cubs are able to land upgrades from outside the organization.

The Mets claimed Anderson off waivers from the Twins on Monday, Anthony DiComo of MLB.com reports.

Anderson appeared in seven games between the Red Sox and Twins in 2026, allowing three runs with a 12:3 K:BB over 12.1 innings of work. He will turn 27 later this month and will provide the Mets with another middle relief option.

Canning's $5 million mutual option for 2027 was declined Monday.

The Padres will pay Canning a $1.5 million buyout instead. Canning got a late start to this season as he continued his recovery from Achilles surgery, and he struggled once healthy in logging a 5.68 ERA over 11 starts and 19 relief appearances.

Thielbar's $6 million mutual option for 2027 was declined on Monday.

Thielbar had an up-and-down 2026 campaign, posting a 4.86 ERA and 60:18 K:BB over 50 regular-season innings. The left-hander will turn 40 in January, but he should be able to land a big-league contract if he wants to continue his career.

The Cubs declined their side of Harvey's (triceps/shoulder) $8 million mutual option for 2027 on Monday.

He'll get a $1 million buyout instead and enter free agency. Harvey made only four appearances for the Cubs in 2026 due to triceps and shoulder woes, and it's unclear what his current health status is. The 31-year-old has the stuff to be a high-leverage reliever, but injuries have been a common theme in his career.

Blue Jays general manager Ross Atkins said last week of Tiedemann that the team is "thinking of him as a reliever" heading into the 2027 season, Shi Davidi of Sportsnet.ca reports.

Tiedemann returned from a nearly two-year absence in 2026 due to Tommy John surgery and multiple setbacks, allowing one run with an 8:6 K:BB over six innings during his brief time in the big leagues. The 24-year-old boasts a 39.1 percent strikeout rate in the minors, but he's logged a total of just 152 innings since being drafted in 2021 because of myriad injuries.

Lovelady was designated for assignment by the Nationals on Sunday, Kyle Williams of TheBanner.com reports.

Lovelady is the odd man out on the 40-man roster after Washington traded for infielder Nate Furman on Sunday. Lovelady produced a 4.11 ERA and 1.86 WHIP with 31 strikeouts over 35 innings in 38 appearances, including six starts, with the Mets and Nationals during the 2026 campaign. He will now be claimed by another team, remain with the Nationals' organization or hit the open market as a free agent.
