Mauricio is not in the lineup for Tuesday's contest versus the Nationals.

Mauricio will be absent from the lineup for a second straight after he had started in each of the three contests prior to that. Brett Baty will hold down third base for the Mets on Tuesday.

Seigler remains out of the lineup for the first game of Tuesday's doubleheader with the Cubs.

Seigler had started at third base in five of the Brewers' first eight games of August as manager Pat Murphy more proactively shielded rookie Caleb Durbin from right-handed pitching, but Durbin has since re-established himself as Milwaukee's clear top option at the hot corner. Over the last nine games, Seigler has cracked the lineup just once while Durbin has started in the other eight contests.

Pauley is expected to miss about four weeks after straining his right oblique over the weekend, MLB.com reports.

That timeline would have the third baseman out until mid-September, and it's possible the Marlins end up shutting him down completely if his recovery has any hiccups. Pauley has slashed .273/.385/.527 over 25 games since the All-Star break with four home runs and an impressive 10:11 BB:K, but his prolonged absence could give Connor Norby (wrist) a chance to reclaim the starting job at the hot corner heading into 2026. While both players remain on the shelf for the time being, Javier Sanoja will likely see the bulk of the playing time at third base.

Arenado (shoulder) was scheduled to meet the Cardinals in Miami and will be evaluated by team doctors Tuesday, Daniel Guerrero of the St. Louis Post-Dispatch reports.

Arenado has been rehabbing his right shoulder strain at the team's spring training complex in Jupiter, FL, and made the short trip to Miami to join the club. It does not seem as though Arenado's activation from the 10-day injured list is imminent, but the Cardinals expect to have a clearer picture of his timetable after he meets with team doctors. Arenado has been sidelined for the entirety of August.

Durbin went 2-for-5 with a home run, a double, two total RBI and a stolen base in a 7-0 win against the Cubs on Monday.

Durbin gave Milwaukee a 2-0 lead with a solo homer in the fifth inning. He added a run-scoring fielder's choice in the eighth, then stole second base. It was the first time this season Durbin has swiped a bag and homered in the same contest. The 25-year-old is slashing .255/.334/.377 with seven home runs, 42 RBI, 46 runs and 11 thefts on the campaign.

Chapman (hand) will take grounders at third base Monday and hit on the field Wednesday in San Diego, Justice delos Santos of The San Jose Mercury News reports.

Chapman has been sidelined since Wednesday with right hand inflammation, but he's now quickly set to begin building back up. The third baseman is eligible to return from the 10-day injured list Saturday, and it's possible he'll be able to do so if his fielding and hitting work goes well in the coming days.

Riley ran the bases Sunday but still felt some abdominal discomfort, Mark Bowman of MLB.com reports.

He will run again Tuesday, but a timeline for Riley's return to the Atlanta roster remains unclear. Riley has been sidelined for most of this month with a strained lower abdominal muscle. Nacho Alvarez will continue filling in at third base for Atlanta until Riley is ready to return from the injured list.

Norby (wrist) will begin a rehab assignment with Triple-A Jacksonville on Wednesday, Christina De Nicola of MLB.com reports.

Norby needed surgery in mid-July to address a fractured hamate bone in his left hand, but he's now ready to test out the surgically repaired wrist in a game setting. If all goes well during his rehab assignment, he should rejoin the Marlins' 26-man active roster before the end of August.

The Marlins placed Pauley on the 10-day injured list Monday with a right oblique strain.

Miami hasn't shed light on the severity of the injury that Pauley sustained over the weekend, but given that even mild oblique strains typically entail more than a 10-day recovery, the 24-year-old is unlikely to return from the IL when first eligible Aug. 27. Miami recalled infielder Maximo Acosta from Triple-A Jacksonville in a corresponding move, but Javier Sanoja and Eric Wagaman may be likelier candidates to pick up starts at third base while Pauley is on the shelf.

Dodgers manager Dave Roberts said that Muncy's (oblique) condition is improving, and the 34-year-old is scheduled to take part in some "rotational" work Monday, Fabian Ardaya of The Athletic reports.

Though Muncy's oblique strain is of the mild variety, the Dodgers are still expecting him to miss more than the minimum 10 days after he landed on the injured list Friday. Muncy is still in the early stages of his recovery program, so a clearer timeline for his return from the IL is unlikely to become available until he's able to take part in full baseball activities. While Muncy has been out of action for the Dodgers' last four games, Alex Freeland has made three starts at third base and Buddy Kennedy has made one start.
