The Marlins transferred Perez (elbow) from the 15-day injured list to the 60-day IL on Thursday.

EDGE Analysis

The transaction came just a few hours after president of baseball operations Peter Bendix announced that Perez would undergo season-ending Tommy John surgery Monday. By transferring the 20-year-old right-hander to the 60-day IL, the Marlins were able to open up a spot on the 40-man roster for utility player Otto Lopez, whom Miami claimed off waivers from San Francisco on Thursday.

Marlins president of baseball operations Peter Bendix announced Thursday that Perez (elbow) will undergo Tommy John surgery Monday, Jordan McPherson of the Miami Herald reports.

EDGE Analysis

Perez was diagnosed with mild inflammation in his right elbow late in spring training and opened the season on the shelf, but he was never shut down from throwing and looked to be tracking toward making his season debut sometime in April. However, after experiencing elbow tightness following a bullpen session Tuesday, Perez met with Dr. Keith Meister, who recommended that the season-ending procedure. Even if no further damage is detected beyond a torn UCL once surgery is performed Monday, the 20-year-old is still likely facing a 14-to-16-month recovery timetable, meaning that he'll be out for a significant portion of the 2025 season as well. The injury is an unfortunate setback for the budding young ace, who disclosed in spring training that he had no history of elbow issues before the inflammation cropped up. He'll join Sandy Alcantara (elbow) among Marlins starters who are out for the season while recovering from Tommy John surgery, but Miami should soon get some reinforcement to its rotation with both Edward Cabrera (shoulder) and Braxton Garrett (shoulder) having recently pitched in rehab games.

Perez (elbow) threw a bullpen session Saturday, Daniel Alvarez-Montes of ElExtraBase.com reports.

EDGE Analysis

Saturday marks the first time Perez has thrown off a mound since experiencing inflammation in his right elbow. He threw 20 pitches during his first session and used his entire arsenal of pitches, and everything seemed to go smoothly. He'll likely require a few more mound sessions before moving onto facing live hitters, and a minor-league rehab assignment should come after that.

Perez (elbow) played catch from 105 feet Friday and mixed in some breaking balls, Jordan McPherson of the Miami Heraldreports.

EDGE Analysis

Perez was placed on the 15-day injured list Thursday and continues ramping up his throwing program after being shut down for a bit due to elbow inflammation. The right-hander should continue stretching out his throwing distance before resuming mound work.

The Marlins placed Perez (elbow) on the 15-day injured list Thursday.

EDGE Analysis

The 20-year-old has been destined for the IL since being diagnosed with elbow inflammation last week, and the Marlins made the transaction official Thursday. Perez resumed throwing over the weekend but will need to time to build up his arm strength, so he should be sidelined well beyond the 15-day minimum.

Pered (elbow) played catch Sunday, Christina De Nicola of MLB.com reports.

EDGE Analysis

The right-hander will begin the season on the 15-day injured list with right elbow inflammation, but his return to throwing is an encouraging development after he was shut down March 15. Perez didn't have a full build-up earlier in camp due to finger issues, so the Marlins are likely to be fairly cautious as he ramps up his throwing program.

Perez will begin the season on the 15-day injured list after being diagnosed with right elbow inflammation, Craig Mish and Barry Jackson of the Miami Herald report.

EDGE Analysis

This qualifies as good news, as Perez was cleared of any structural damage in his pitching elbow and will not require surgery. He will, however, still be sidelined for several weeks while the inflammation subsides. If there's a silver lining -- beyond the lack of structural damage -- Perez's recurring fingernail issue will have more time to heal. Fantasy managers should prepare to be without the 20-year-old for at least the first month or so, but a clearer timetable figures to be available in the coming weeks.

Perez reported soreness in his elbow Thursday following his appearance in Wednesday's spring game against Washington, Jordan McPherson of the Miami Herald reports.

EDGE Analysis

Perez had to leave his appearance Wednesday after experiencing discomfort with the broken nail on his right middle finger. Now, Perez's elbow issue poses another threat to potentially delaying his start to the regular season. Perez will undergo further imaging and testing over the next few days to determine the severity of his injury, but it appears increasingly likely that Perez will miss the beginning of the regular season.

Perez (finger) will be shut down from throwing for 3-to-4 days, Craig Mish of the Miami Herald reports.

EDGE Analysis

Perez had to be removed from his last Grapefruit League outing after just 14 pitches due to complications with a fingernail issue on his right middle finger. The right-hander had previously expressed optimism that he could still ramp back up in time for Opening Day, but this shutdown period, while relatively brief, makes a start during the opening weekend of the season unlikely. Perez was already in line to have his workload monitored this season, so it might make sense for the Marlins to push back his debut until at least the second turn through the rotation. The Marlins are already juggling injuries to other starters like Braxton Garrett (shoulder) and Edward Cabrera (shoulder), however, and the fact that Miami plays eight straight games to begin the campaign before its first off day could also push the team to try and get Perez ready to go as soon as possible.

Perez still believes he'll be able to build up properly ahead of Opening Day despite the fingernail issues that have plagued him this spring, Christina De Nicola of MLB.com reports.

EDGE Analysis

The precocious 20-year-old right-hander threw only 14 pitches Wednesday due to a recurrence of the issues -- which is problematic when he was scheduled to get up into the 70-pitch range and days are running short on the Grapefruit League calendar. Perez says his early exit wasn't due to his nail splitting again however, but rather that the fake nail he was wearing to protect it began to lift up. "I don't know yet," Perez said Wednesday when asked what the next step in his preparations for the regular season would be. "I spoke with [head athletic trainer] Lee [Meyer], and he told me that we will tackle this early [Thursday], and we're going to make sure we have a plan so this doesn't happen during the season." As yet, Perez's availability for Opening Day doesn't appear to be in real jeopardy, but one more truncated spring outing simply won't leave him enough time to get built up.
