Cronin is managing left hip discomfort and won't be included on Miami's Opening Day roster, Christina De Nicola of MLB.com reports.

EDGE Analysis

The right-hander surrendered nine runs in 5.2 innings during spring training before Miami backed off his throwing program due to the hip issue. Cronin made 56 appearances for the Marlins last year and had a 4.35 ERA, 1.42 WHIP and 72:25 K:BB over 70.1 innings. It's unclear how long he's expected to be sidelined by the hip issue.

Cronin (knee) is scheduled to make his second appearance of Grapefruit League play Monday versus the Astros, Kevin Barral of FishonFirst.com reports.

EDGE Analysis

In his first season with Miami in 2024, Cronin submitted a 4.35 ERA, 1.42 WHIP and 72:25 K:BB across 70.1 innings over 56 relief appearances, but he didn't pitch in the final week of the campaign after landing on the injured list due to left knee tendinitis. The injury doesn't seem to have delayed him in spring training, but Cronin may need to close camp on a high note to ensure he clinches a spot in Miami's Opening Day bullpen. He lacked command in his first spring outing Thursday against St. Louis, recording two outs while allowing two earned runs on two hits while also hitting a batter and throwing a wild pitch.

The Marlins placed Cronin on the 15-day injured list Friday with left knee tendinitis, Christina De Nicola of MLB.com reports.

EDGE Analysis

Cronin dealt with an undisclosed injury a few weeks ago, but it's unclear whether that was knee related. The reliever's season will end with him having posted a 4.35 ERA and 72:25 K:BB over 70.1 innings covering 56 appearances.

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.

EDGE Analysis

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.

Cronin was removed from Thursday's game against the Rockies due to an apparent injury, Christina De Nicola of MLB.com reports.

EDGE Analysis

Cronin was able to remain in the game after his first visit from the Marlins' training staff, though the decision was eventually made to pull him after he had trouble fielding a groundball in the sixth inning. It's not immediately apparent what is bothering the 26-year-old righty, but the team should have some more information on his status sometime after the game.

Cronin has posted a 3.72 ERA, 1.46 WHIP and 49:17 K:BB through 46 innings with one win, two holds and zero saves over 33 appearances.

EDGE Analysis

Claimed off waivers over the winter, Cronin gave the Marlins some quality innings early in the season in a low-leverage role. The league may have figured the right-hander out however -- over his last 12 appearances, he carries a rough 8.27 ERA and 1.84 WHIP. Cronin's biggest strength is a 54.5 percent groundball rate, but he's still been somewhat fortunate to have allowed zero homers so far in 2024. If that luck runs out, further regression could be coming for his ERA. Even if Miami ships out high-leverage relievers like Tanner Scott by the trade deadline, Cronin seems unlikely to take over a prominent role.

Cronin gave up a hit and struck out one in 1.2 scoreless innings Wednesday, recording his first hold of the season in a win over the Tigers.

EDGE Analysis

The 26-year-old right-hander entered the game in the sixth inning with the Marlins ahead 2-0 and blanked Detroit over 22 pitches (14 strikes) before passing the baton to Andrew Nardi in a combined shutout. Cronin isn't seeing consistent high-leverage usage, but he's been one of the few bright spots in Miami's bullpen this season, posting a 1.33 ERA, 1.28 WHIP and 22:10 K:BB through 20.1 innings in a long-relief role.

Cronin was recalled from Triple-A Jacksonville by the Marlins on Wednesday, Christina De Nicola of MLB.com reports.

EDGE Analysis

Cronin made two scoreless relief appearances for the Marlins earlier this season and returns to give the bullpen a fresh arm. He'll operate in middle relief.

The Marlins optioned Cronin to Triple-A Jacksonville on Sunday.

EDGE Analysis

The right-hander earned a place on Miami's Opening Day roster and appeared in two of the first three games, but he's now being sent to Triple-A. Cronin allowed one unearned run on three hits with a 4:3 K:BB across four innings, which should give him a chance to rejoin the big club later in the season.

Cronin will begin the season as part of the Marlins' bullpen.

EDGE Analysis

The 26-year-old right-hander was claimed off waivers from the Astros just before the start of spring training and delivered an 11:5 K:BB through 10.2 Grapefruit League innings for the Marlins. Cronin is expected to work in lower-leverage situations, although his sinker could get him the occasional hold opportunity when Miami needs a double play.
