Castillo agreed to a minor-league contract with the Diamondbacks on Monday.

Castillo has been given an invitation to the major-league side of spring training. The 27-year-old left-hander spent nearly all of 2023 at the Triple-A level, posting a 7.65 ERA and 48:24 K:BB over 37.2 frames. He boasts a 55:16 K:BB over 40.1 career innings in the majors.

Sanmartin (elbow) signed a minor-league contract with the Reds on Nov. 19.

Sanmartin underwent Tommy John surgery in early July before being non-tendered by the Reds in mid-November. While it's unclear whether his new minor-league contract is a one-year or two-year deal, he'll at least be able to begin his recovery process as part of the organization.

Mills (elbow) signed a two-year, minor-league contract with the Red Sox on Sunday, Chris Cotillo of The Springfield Republican reports.

Jensen was designated for assignment by the Mariners on Wednesday.

Seattle had to free up a 40-man roster spot after acquiring both Seby Zavala and Carlos Vargas from the Diamondbacks on Wednesday in exchange for Eugenio Suarez.

The Mariners acquired Vargas and Seby Zavala from the Diamondbacks in exchange for Eugenio Suarez on Wednesday, Ryan Divish of The Seattle Times reports.

Vargas posted a 5.79 ERA and 7:4 K:BB over 4.2 innings with Arizona and a 7.02 ERA and 36:32 K:BB across 42.1 frames at Triple-A Reno in 2023. While the control problems are worrisome, Vargas has a huge arm and could develop into a late-inning weapon if he can throw enough strikes.

St. Louis re-signed Rodriguez (shoulder) to a minor-league contract Tuesday with an invitation to major-league spring training, Jeff Jones of the Belleville News-Democrat reports.

Rodriguez was outrighted off the Cardinals' 40-man roster earlier this month, but he'll return as organizational depth for the 2024 season. The 33-year-old right-hander missed most of 2023 after undergoing arthroscopic shoulder surgery in early May, though he should be fully recovered by now.

Cox (knee) signed a minor-league contract with the Royals on Saturday.

After being designated for assignment and later non-tendered by the Royals on Friday, the team will now bring Cox back to round out their farm system for next season. The 26-year-old southpaw put up a 4.54 ERA over 35.2 frames during his first season in the majors before tearing the ACL and damaging the MCL in his left knee in September. The injury will likely cause him to miss the beginning of next season.

Covey signed a one-year contract with the Phillies on Friday, avoiding arbitration.

Covey was claimed off waivers from the Dodgers this past May and went on to deliver a solid 3.69 ERA across 39 innings of work with Philly. He projects to fill a long-relief role in 2024.
