The Blue Jays signed Castro to a minor-league contract with an invitation to spring training, Ari Alexander of WHDH 7News in Boston reports.

Castro spent the 2025 campaign at Triple-A Lehigh Valley in the Phillies organization, slashing .235/.324/.421with 19 homers and 18 steals over 133 contests. The 26-year-old utility infielder last appeared in the majors in 2023 and is likely to begin next season at Triple-A Buffalo.

Hader (shoulder) stated Monday that he feels back at full strength after completing his rehab program a few weeks ago, Matt Kawahara of the Houston Chronicle reports.

Hader's 2025 season came to an early end after he was diagnosed with a left shoulder strain, but he's feeling strong after finishing up his rehab. The lefty noted Monday that he thinks he'll be able to throw as he normally would leading up to spring training. "It should be normal," said Hader. "Obviously, intensity gets up and we'll see how that goes and how I'm recovering, bouncing back from that. But as of now, everything is status quo, back to normal."

Krook agreed to a minor-league contract with the Athletics on Saturday.

Krook elected free agency earlier in the month after being sent outright to Cleveland's Triple-A affiliate, and he's since decided to return to the A's. He made three appearances for the Athletics during the 2025 season, surrendering two runs on five hits and one walk while striking out three over 3.1 innings.

The Yankees signed Rodriguez (elbow) to a minor-league contract Monday.

Per Steve Adams of MLB Trade Rumors, it's a two-year deal for Rodriguez, who is aiming to return around midseason after having Tommy John surgery this past spring. The 28-year-old reliever holds an 8.17 ERA and 33:19 K:BB over 36.1 innings covering parts of three seasons at the big-league level.

The Mets are finalizing a trade that will send Nimmo to the Rangers in exchange for infielder Marcus Semien, Jeff Passan of ESPN.com reports.

Nimmo is coming off a 2025 campaign during which he posted a .760 OPS with 25 home runs, 92 RBI and 13 stolen bases over 652 regular-season plate appearances. He also played in a career-high 155 contests and has been relatively durable in recent campaigns, logging at least 151 appearances every year since 2022 despite managing a foot injury. Nimmo should immediately take on a starting role in the Rangers' outfield and will be looked to for some pop, as he's averaged 24 regular-season long balls over the past three years. However, his defense has slipped of late (probably at least in part due to the foot issue), and he has five years remaining on his current deal, which may explain why the Mets decided to move him. Nimmo has a full no-trade clause in his contract, but he's already approved the deal, per Will Sammon of The Athletic.

Vazquez cleared waivers and was outrighted to Triple-A Norfolk on Sunday, Jake Rill of MLB.com reports.

The 26-year-old was designated for assignment Tuesday, but he'll stick in the organization after passing through waivers unclaimed. Vazquez played 36 games for the Orioles last season and had a .160/.208/.240 slash line in 53 plate appearances.

Festa agreed to a one-year, $1 million contract with the Guardians on Friday to avoid arbitration, Paul Hoynes of The Cleveland Plain Dealer reports.

Festa pitched a career-high 54.2 innings in 2025 while also maintaining a solid 1.08 WHIP with a 56:15 K:BB. He also racked up 12 holds and should line up for a high-leverage role out of the bullpen once again in 2026.

Fry (face) agreed to a one-year, $1.38 million contract with the Guardians on Friday to avoid arbitration, Paul Hoynes of The Cleveland Plain Dealer reports.

Fry had a tough 2025 season, as he was initially sidelined until the end of May while recovering from an elbow injury. His season ended in late September after being hit in the face by a pitch, though that isn't expected to affect his 2026 campaign. In between, Fry struggled to a .171/.229/.363 line across 157 plate appearances.

Haggerty agreed to a one-year contract with the Rangers on Friday, avoiding arbitration.

Haggerty inked a minor-league deal with Texas in February and was up in the big leagues six weeks into the regular season. The 31-year-old primarily worked in a utility role and had a .253/.328/.370 slash line with 12 steals and 31 runs in 181 plate appearances.

Jones (oblique) agreed to a one-year, $2 million contract with the Guardians on Friday to avoid arbitration, Paul Hoynes of The Cleveland Plain Dealer reports.

Jones' season regular-season ended a few days early due to an oblique injury, an issue that also sidelined him for the postseason. He spent the entire 2025 season in the majors and accrued 403 plate appearances, though he managed only a .600 OPS with five homers and eight stolen bases.
