The Mets re-signed Waddell to a one-year contract Tuesday.

Waddell held a 3.45 ERA and 22:11 K:BB over 31.1 innings for the Mets in 2025. He was used primarily as a starter this season at Triple-A Syracuse, where he posted a 5.02 ERA and 63:25 K:BB in 75.1 innings. Waddell does not have minor-league options remaining, so he would have to be passed through waivers in order to be sent to the minors if he doesn't make the Opening Day roster.

The Orioles acquired Kittredge from the Cubs on Tuesday in exchange for cash considerations.

Kittredge was dealt from the Orioles to the Cubs at the trade deadline and is now headed back to Baltimore. The Orioles have a $9 million option on Kittredge for 2026, which they will now presumably exercise. Kittredge posted a 3.40 ERA, 0.98 WHIP and 64:11 K:BB over 53 regular-season innings between the Orioles and Cubs in 2025. Baltimore has an opening at closer for 2026 and Kittredge could be the current favorite to fill it, though the team is likely to add additional relievers this offseason.

Atlanta released Wiles on Tuesday, David O'Brien of The Athletic reports.

Wiles was knocked around in his lone appearance with Atlanta in 2025, allowing three runs over one inning of work in his major-league debut. The 27-year-old pitched well at Triple-A Gwinnett, collecting a 3.04 ERA and 105:34 K:BB across 112.2 frames. Wiles has experience as a starter and as a reliever.

The Mariners exercised Munoz's $6 million option for 2026, Francys Romero of BeisbolFR.com reports.

Munoz saved 38 regular-season games while posting a 1.73 ERA and 83:28 K:BB over 62.1 innings, so the Mariners made the easy decision to retain him at a bargain rate in 2026. The club also has an $8 million option for 2027 and $10 million option for 2028 on Munoz. The hard-throwing reliever should be one of the best closers in baseball again next season.

The Mets acquired Gerber from the Rays on Tuesday in exchange for cash considerations, Anthony DiComo of MLB.com reports.

Gerber was removed from the Rays' 40-man roster Monday and is now on the move to a new organization. The 28-year-old reliever spent most of the 2025 season at Triple-A Durham, where he posted a 6.23 ERA but struck out 54 over 43.1 innings.

The Mets exercised Raley's $4.75 million option for 2026 on Tuesday.

Raley was sharp in the second half after making his way back from Tommy John surgery, posting a 2.45 ERA, 0.78 WHIP and 25:6 K:BB over 25.2 innings. The 37-year-old reliever will handle a high-leverage relief role for the Mets in 2026.

The Mets declined Smith's (elbow) $2 million option for 2026 on Tuesday, Anthony DiComo of MLB.com reports.

Smith didn't pitch at all in 2025 after having Tommy John surgery with an internal brace in July 2024. He is expected to be ready for the beginning of next season, but the Mets decided against bringing him back at the $2 million rate his option required. Smith has a career 3.48 ERA and 24.5 percent strikeout rate, so the 32-year-old reliever should draw interest in free agency.

The Diamondbacks declined Rodriguez's $1.35 million option for 2026 on Tuesday, Francys Romero of BeisbolFR.com reports.

Rodriguez was a waiver claim of the Diamondbacks in September but never made an appearance for them. The 27-year-old collected a 9.15 ERA and 18:7 K:BB over 19.2 frames between the Brewers and Orioles in 2025. Rodriguez pitched for Japan's Yakult Swallows for part of 2023 and all of 2024, and Romero notes that several teams in Asia have expressed interest in the righty.

McArthur (elbow) has begun a throwing program, MLB.com reports.

McArthur missed the entire 2025 season following surgery last offseason to address an olecranon fracture in his right elbow. He required a follow-up procedure in July to remove one of the two screws inserted into the elbow and only just recently was cleared to throw again. McArthur is scheduled for a follow-up appointment in mid-November to make sure his elbow is healing as expected.

Erceg (shoulder) will undergo imaging Monday in hopes of being cleared to begin a throwing program, MLB.com reports.

Erceg landed on the 15-day injured list in mid-September due to a right shoulder impingement. As long as scans Monday come back clean, the reliever should have a normal offseason. Erceg notched two saves and 22 holds for the Royals in 2025 and is slated to enter the 2026 campaign in a setup role.
