Bellozo was pulled from Tuesday's game against the Nationals with right triceps tightness, Kevin Barral of FishonFirst.com reports.

Bellozo gave up two hits and struck out a batter across two-plus innings out of the bullpen Tuesday before his triceps forced him out during the ninth. The severity of his injury remains unknown, though the Marlins will presumably stay away from using Bellozo in relief over the next couple of days.

The Padres optioned Jacob to Triple-A El Paso on Tuesday.

Michael King (knee) was activated from the 15-day injured list and is starting Tuesday, so Jacob was optioned to make room. Jacob made three appearances after being recalled Sept. 2, allowing one earned run on two hits with a 3:3 K:BB across 3.1 innings.

The Dodgers optioned Casparius to Triple-A Oklahoma City on Tuesday.

Casparius had been having a solid stretch since July 25 as he notched a 2.63 ERA across 13.2 innings in that span. However, he loses his spot on the active roster to Alex Vesia (oblique), who was activated from the 15-day injured list Tuesday.

The Dodgers reinstated Vesia (oblique) from the injured list Tuesday.

A right oblique strain has kept Vesia on the shelf since Aug. 21, though he pitched two shutout innings while striking out three batters in two rehab appearances at Triple-A Oklahoma City. Now fully healthy, the 29-year-old southpaw will reclaim a high-leverage role in the Dodgers' bullpen after posting a 2.75 ERA and 0.99 WHIP through 52.1 innings before his injury. Ben Casparius was optioned to Oklahoma City in a corresponding move.

The Brewers optioned Rodriguez to Triple-A Nashville on Tuesday.

Rodriguez tossed 1.1 scoreless frames in Monday's loss to the Rangers but finds himself back in the minors a day later. His spot on the roster will be absorbed by Chad Patrick, who is starting Tuesday's game in Texas.

Miller will undergo surgery in the coming weeks to repair the torn UCL in his right elbow, Curt Hogg of the Milwaukee Journal Sentinel reports.

It's unclear whether it will be Tommy John surgery -- which would be Miller's second -- but even if it isn't there's a good chance he won't be ready to pitch again until 2027. The righty posted a 2.74 ERA and 54:15 K:BB over 46 innings between the Diamondbacks and Brewers this season and will be a free agent this offseason.

Hall (oblique) has been cleared to resume a throwing program, Adam McCalvy of MLB.com reports.

Hall had been limited to plyometric work but has begun throwing on flat ground. The lefty will continue to ramp things up, with the goal of returning in late September or early October. Hall has been sidelined since mid-August with a strained right oblique.

The Mets designated Suero for assignment Tuesday.

The right-hander was optioned to Triple-A Syracuse last week and has now lost his place on the 40-man roster. Suero made a few big-league appearances with Atlanta earlier this season but surrendered eight earned runs across 6.1 innings.

Mears (back) played catch from 105 feet Tuesday, Curt Hogg of the Milwaukee Journal Sentinel reports.

The right-hander landed on the shelf last week due to back tightness but wasn't shut down from throwing for long. Mears will be eligible to be reinstated Sept. 17, and the Brewers are targeting that date or shortly after for his return from the injured list.

Megill (elbow) threw a successful live batting practice session Tuesday, Adam McCalvy of MLB.com reports.

It was the first time Megill faced hitters since he was diagnosed with a Grade 1 right flexor strain in late August. He could thrown one more live batting practice session before being sent out on a rehab assignment. Megill is aiming to be activated from the 15-day injured list next Tuesday, and thus far, he seems on track to achieve that goal.
