Miami Marlins right-hander Declan Cronin (hip) is restarting his minor-league rehab assignment with Single-A Jupiter on Tuesday, according to MLB.com's Christina De Nicola. Cronin suffered a setback with his hip while on a rehab assignment with Triple-A Jacksonville in mid-April, but the 27-year-old reliever is now ready to pitch in games again. He is finally trying to get over the hump while dealing with a strained left hip. If he can avoid any setbacks this time around, it's possible that Cronin could rejoin Miami's bullpen by the end of May. He has not pitched in the big leagues yet in 2025 because of his hip injury and won't really on the radar in fantasy leagues out of the bullpen. Cronin posted a 4.35 ERA (2.58 FIP) and 1.42 WHIP with 72 strikeouts and 25 walks in 70 1/3 innings pitched over 56 relief appearances with the Marlins a year ago.

Miami Marlins right-handed pitcher Declan Cronin (hip) has been progressing well in his rehab assignment. According to Kevin Barral of Fish on First, the right-hander is set to throw a pitch design on Tuesday. Cronin has been sidelined on the 15-day injured list since March. Cronin has made three rehab appearances with Triple-A Jacksonville. In each appearance, Cronin logged just one inning of work. Across three total frames, the 27-year-old has allowed two runs (one earned) and has struck out four batters. Last season, the Holy Cross product logged a career-high 70 1/3 innings and held a 4.35 ERA with a 1.42 WHIP. He was deployed exclusively out of the bullpen. When he is cleared to return, fantasy managers should expect Cronin to operate in a middle relief role.
