Rangers' Declan Cronin: Inks two-year MiLB deal with Texas
Rotowire
Cronin (elbow) signed a two-year, minor-league contract with the Rangers on Tuesday, Bob Nightengale of USA Today reports.
Cronin is slated to miss the entire 2026 campaign after undergoing Tommy John surgery at the end of September, so the Rangers will bring him in on a two-year deal with the hope of having him contribute to the organization in 2027. When healthy, the 28-year-old reliever turned in a 4.91 ERA and 1.64 WHIP across 22 innings at Triple-A in 2025.

Declan Cronin: Cut by Fish
Rotowire
The Marlins released Cronin (undisclosed) on Saturday.
Cronin has been shut down at Triple-A Jacksonville since mid-August with an undisclosed injury, and he'll now end up in free agency to make room on Miami's 40-man roster for right-hander Christian Roa, whom the Marlins called up from the minors. Cronin sports a 4.91 ERA and 1.64 WHIP through 22 innings at Jacksonville but should be able to attract a minor-league deal on the open market.

Marlins' Declan Cronin: Activated, optioned to Triple-A
Rotowire
The Marlins reinstated Cronin (hip) from the injured list Saturday and optioned him to Triple-A Jacksonville.
A hip strain has kept Cronin on the injured list all season, and although he's given up just two earned runs in eight innings during his rehab assignment, the Marlins are going to keep him in the minors now that he's fully healthy. Miami doesn't have a particularly deep bullpen, however, so Cronin could definitely work his way back into the majors if he continues to perform well in Jacksonville.

Cronin sustained a left hip strain late in spring training, resulting in him opening the season on the injured list.

Marlins' Declan Cronin: Moves past undisclosed injury
Rotowire
Cronin (undisclosed) struck out two batters and collected a hold across two perfect innings of relief in his first two appearances of September on Wednesday and Saturday.
Cronin was lifted during an extended relief appearance Aug. 29 in Colorado due to an apparent injury, but he returned to action just under a week later to remove any lingering concern about his health. The 26-year-old righty has picked up four of his six holds on the season in the past month and could be primed to pitch in more high-leverage situations down the stretch with Calvin Faucher (shoulder) recently joining Andrew Nardi (elbow) on the shelf.

As Jesse Scholtens heads to the injured list, Cronin will return to the major-league roster a day after being optioned to the minors. The 26-year-old righty has given up 10 runs through 7.2 innings with the White Sox this season, so he likely still won't see much action while with Chicago.
