Marlins manager Clayton McCullough said Tuesday that Bellozo will be part of the team's Opening Day rotation, Christina De Nicola of MLB.com reports.

Bellozo was optioned to Triple-A Jacksonville earlier this month, but the Marlins are in need of reinforcements with Ryan Weathers (forearm) and Edward Cabrera (blister) going down. The 25-year-old Bellozo managed a 3.67 ERA for Miami last season, but that came with a 5.72 FIP. His leash in the role will be short.

Rea is expected to begin the season working as a reliever after Ben Brown was named the Cubs' No. 5 starter Tuesday, Sahadev Sharma of The Athletic reports.

Rea appeared to have the upper hand for Chicago's final rotation spot after Jordan Wicks was optioned to Triple-A Iowa last week, but Ben Brown will instead get the nod with Javier Assad (oblique) on the shelf. Rea is likely to receive some starts at some point this season, but his 4.29 ERA and 7.2 K/9 across 167.2 regular-season innings with Milwaukee last year suggest he won't have much fantasy relevance.

The Cubs informed Brown on Tuesday that he will begin the season as the club's No. 5 starter, Sahadev Sharma of The Athletic reports.

The 25-year-old took the loss out of the bullpen in the season opener in Japan last week as he surrendered three runs (two earned) across 2.2 innings, but he apparently showed enough during camp to win the rotation spot. Brown started in eight of his 15 appearances as a rookie last year and had a 3.58 ERA, 1.08 WHIP and 64:19 K:BB across 55.1 innings, and he may need to perform similarly this year to retain the rotation spot since Javier Assad (oblique) will potentially return early in the season.

Montgomery will undergo Tommy John surgery next week, Nick Piecoro of The Arizona Republic reports.

Montgomery had seemed like a good bet to be traded eventually, but that's not going to happen now. The surgery ends a nightmarish stint in Arizona, as Montgomery posted a 6.23 ERA last season after signing late and never getting on track. He will be a free agent this winter and likely miss at least the first couple months of the 2026 season.

The Rangers optioned Corbin to Triple-A Round Rock on Tuesday, Shawn McFarland of The Dallas Morning News reports.

Corbin's tenure meant he had to agree to being sent down, which he did so that he could continue to build up stamina after signing with the Rangers last week. He is slated to make two starts in the minors, with the goal of joining the Rangers' rotation April 11 against the Mariners.

Rangers president of baseball operations Chris Young said Tuesday that Leiter will open the season in the team's rotation, Evan Grant of The Dallas Morning News reports.

Leiter showed an increase in velocity this spring while striking out 21 over 20.2 innings. He also walked 10, and whether the 24-year-old is ultimately able to throw enough strikes will go a long way in determining how successful he'll be. The upside is certainly there, but there's also risk.

Rangers president of baseball operations Chris Young said Tuesday that Rocker will be in the team's Opening Day rotation, Evan Grant of The Dallas Morning News reports.

Injuries to Jon Gray (wrist) and Cody Bradford (elbow) seemed to make this a foregone conclusion, and now it's official. Rocker mostly struggled this spring, but he ended on a high note with eight strikeouts over 4.2 innings in his final Cactus League outing. The 25-year-old's workload in 2025 will be curtailed to some degree after he threw only 48.1 innings in 2024 following a return from Tommy John surgery.

The Rangers outrighted Dunning to Triple-A Round Rock on Tuesday, Evan Grant of The Dallas Morning News reports.

Dunning passed through waivers unclaimed, with his $2.66 million salary likely being a major reason why. He will remain in the organization and could be used in the Round Rock rotation.

Rodriguez (elbow) said Tuesday that he intends to throw a bullpen session later this week, Jacob Calvin Meyer of The Baltimore Sun reports.

Additionally, Rodriguez said that recent imaging conducted on his right elbow revealed no ligament damage and confirmed the original diagnosis of inflammation/tendinitis, per Meyer. Though Rodriguez appears optimistic that he'll avoid an extended absence, he essentially started over in his throwing progression last week. Rodriguez has been steadily increasing his throwing distance off flat ground, and since he's thus far avoided any setbacks, he looks poised to take the next step forward by getting back on a mound. Rodriguez will need to complete multiple bullpen sessions before advancing to facing live hitters, and eventually, getting stretched out over multiple minor-league rehab starts or simulated games. While the Orioles aren't providing an official timeline for Rodriguez's return, he appears likely to miss most or all of the first month of the season.

Herz was diagnosed Tuesday with a left elbow UCL sprain, Andrew Golden of The Washington Post reports.

Herz's velocity was down this spring, which originally attributed to a "dead arm" phase. However, as it turns out, he's dealing with an injury that often requires season-ending UCL surgery, although it's not yet clear whether Herz might try the rest-and-rehab route first. At minimum, the lefty is likely to be out a few months, and in all likelihood, much longer.
