Henderson has left Orioles camp Thursday due to a personal matter, Andy Kostka of TheBaltimoreBanner.com reports.

Henderson is expected back Sunday, so the brief absence shouldn't greatly affect his preparation for the season. The young shortstop is looking to bounce back at the plate in 2026 after a nagging shoulder issue contributed to his home-run total dropping from 37 to 17 season over season.

Marte will receive opportunities to play center field this spring, C. Trent Rosecrans of The Athletic reports.

TJ Friedl is expected to get the most starts in center field this season, but the Reds want to see how Marte handles the new position. Marte moved from third base to right field in 2025, and though there were growing pains, he eventually proved himself to be competent and enters 2026 as the primary starter in right.

Riley (core) took live batting practice Wednesday and appears to be facing no restrictions for the start of spring training, Mark Bowman of MLB.com reports.

Riley appears to be 100 percent healthy after he missed most of the final two months of 2025 with a lower abdominal strain, which he ultimately addressed via core-muscle surgery Aug. 21. Though his reputation as one of baseball's more durable third basemen has taken a hit after two straight injury-shortened seasons, Riley won't turn 29 years old until April, and with some better luck on the health front, he could re-emerge as the consistent 30-homer, 90-RBI producer that he was from 2021 through 2023.

Mayo has been working out at third base early in Orioles camp and could see playing time at the position if Jordan Westburg (oblique) shifts to second base to cover for Jackson Holliday's (hand) expected absence to begin the season, Matt Weyrich of The Baltimore Sun reports.

Mayo didn't see any action at third base with the big club from June on last season, focusing on first base and designated hitter instead. However, with Holliday slated to begin the season on the injured list and with offseason pickup Pete Alonso locked in as the Orioles' everyday first baseman, Mayo is being reconsidered as an option at the hot corner. The likelier scenario seems to be Blaze Alexander picking up Holliday's reps, but Mayo could change minds with a strong Grapefruit League showing.

The Red Sox acquired Monasterio on Monday in a trade with the Brewers, Mark Feinsand of MLB.com reports.

Monasterio offers a steady glove at multiple infield spots and he improved offensively with the Brewers in 2025, slashing .270/.319/.437 with four home runs over 68 regular-season contests. The 28-year-old enters a crowded infield picture for the Red Sox and will most likely open 2026 in a reserve role.

The Red Sox acquired Durbin (elbow), Andruw Monasterio, Anthony Seigler and a Comp B pick from the Brewers on Monday in exchange for Kyle Harrison, David Hamilton and Shane Drohan, Jeff Passan of ESPN.com reports.

Durbin had a solid rookie season in Milwaukee, slashing .256/.334/.387 with 11 home runs and 18 stolen bases over 136 regular-season contests. Slated to turn 26 later this month, Durbin mostly played third base for the Brewers and that could be where he slots in for the Red Sox, but he's also an option to handle second base. Durbin underwent arthroscopic elbow surgery in October but should be ready to go for the beginning of spring training.

Baty has been working out in left field this offseason, and he'll continue getting reps at the position this spring, Anthony DiComo of MLB.com reports.

Top prospect Carson Benge appears to be the Mets' Plan A in left, but the 23-year-old may not be quite ready to make the leap to the majors after playing only 24 games at Triple-A last year with a poor .583 OPS. That would leave Baty and Tyrone Taylor as the best remaining options to fill LF, potentially in a platoon that would favor Baty as the left-handed hitter. Baty does have a bit of experience in left field, playing 29 games there for Double-A Binghamton in 2021-22, and the offseason acquisitions of Marcus Semien, Bo Bichette and Jorge Polanco leave no room in the infield for the natural third baseman. Baty is also a better hitter than Taylor, whose value mainly comes from his glove -- from Aug. 1 to the end of the regular season in 2025, Baty slashed .308/.370/.496 with seven homers in 146 plate appearances.

The Cardinals claimed Ramos off waivers from Baltimore on Friday, asdFrancys Romero of BeisbolFR.com reports.

The Orioles acquired Ramos from the White Sox via trade Sunday, but the 23-year-old infielder was designated for assignment by Baltimore on Wednesday. Ramos will now head to St. Louis after being claimed off waivers. Ramos appeared in just four big-league games with the White Sox in 2025, instead spending most of his time at Triple-A Charlotte, where he slashed .216/.309/.396 with 16 home runs and 13 stolen bases over 431 plate appearances. He'll likely provide organizational depth for the Cardinals.

Pauley may be the favorite to win the Marlins' starting job at third base over Connor Norby due to his superior defense, Christina De Nicola of MLB.com reports.

A platoon could also emerge between the lefty-swinging Pauley and the right-handed Norby if neither seizes the starting gig this spring. However, Pauley would seem to have the edge after recording six Outs Above Average last season, tied for fifth among third baseman, while seeing his offense pick up in the second half. Norby is also expected to get some work in the outfield during camp, which could signal a transition into a utility role. Pauley slashed a respectable .250/.367/.474 over 90 plate appearances after the All-Star break in 2025 with four homers, two steals and a sharp 14:15 BB:K.

Henderson worked out at Tinsley Performance this offseason with the goal of increasing his speed, Andy Kostka of The Baltimore Banner reports.

Henderson stole 30 bases in 2025 and ranked in the 79th percentile in sprint speed, but he believes he had room for improvement. Specifically, the 24-year-old has been working on his first few steps, staying more horizontal rather than getting too vertical too soon. Henderson had a disappointing 2025 season at the plate while playing through a shoulder impingement for much of the year, but he's fully healthy now and is a good bet to have a bounce-back showing in 2026.
