The Orioles claimed Ramos off waivers from the Cardinals on Friday, Francys Romero of BeisbolFR.com reports.

Ramos has been bouncing around for the past month after he was DFA'd by the White Sox in January. Chicago then traded Ramos to Baltimore, but the Orioles then DFA'd the third baseman before the Cardinals claimed him and then designated Ramos for assignment themselves earlier this week. Ramos will provide organizational corner infield depth for the Orioles if he sticks around.

Mayo could be the Orioles' Opening Day third baseman following an injury to Jordan Westburg (elbow), Brendan Mortensen of MASNSports.com reports.

Westburg is set to miss at least the first month of the season due to a partially torn UCL in his right elbow. Mayo was primarily a third baseman in the minors before the Orioles had him focus mostly on first base last season. However, there is a clear need at the hot corner now, so the 24-year-old is in line to return to his old position. Mayo has mostly struggled at the big-league level, but the former top prospect showed signs of life last September, slashing .301/.393/.548 with five homers.

Rumfield will have a chance to win a roster spot at first base this spring, Patrick Saunders of the Denver Post reports.

The Rockies acquired Rumfield in an unheralded trade in late January, but he'll have the chance to immediately contribute for his new club. Colorado has competition across most of its infield this spring, and manager Warren Schaeffer said that the starting role at first base is "wide open." Rumfield was previously blocked in the Yankees organization, but he posted a 121 wRC+ across 587 plate appearances at Triple-A Scranton/Wilkes-Barre in 2025. He also won a Gold Glove with Double-A Somerset in 2023, so his glove could also help his case for a roster spot.

Triolo is expected to start at third base for the Pirates to begin the 2026 season, Kevin Gorman of the Pittsburgh Tribune-Review reports.

Triolo is an elite defender at both second and third base, and he is also capable of filling in at shortstop. The Pirates value that versatility, but the team has failed to land any of their targets at third base this offseason. That leaves Triolo as the favorite to start at the hot corner, though his productivity as a hitter could dictate his ability to remain an everyday player. Triolo has a career 87 wRC+ across 1,031 plate appearances, though he posted a 117 wRC+ across 216 plate appearances in the second half of 2025.

Mayo could see increased opportunity at third base for the Orioles if Jordan Westburg (oblique/elbow) has to miss time, Andy Kostka of The Baltimore Banner reports.

Westburg is now dealing with an elbow injury in addition to an oblique strain, and his long-term status is uncertain. The Orioles had seemingly moved on last season from Mayo playing third base, preferring to use him instead at first base, but now the team could have a much larger need at the hot corner. Mayo has been getting lots of reps at third base in camp and could be the Opening Day starter there if Westburg is shelved. Blaze Alexander is also a candidate to play third base, though he could be needed at second base initially while Jackson Holliday (hand) is out. Mayo has slashed just .201/.285/.349 with a 31.2 percent strikeout rate in the majors, but he did perk up last September with regular playing time, hitting .301/.393/.548 with five homers.

Reimer worked hard on improving his defense at third base in the offseason, Tim Britton of The Athletic reports.

The 21-year-old is coming off a breakout campaign with his bat, as he slashed .282/.381/.490 over 123 games between High-A Brooklyn and Double-A Binghamton with 17 homers and 15 steals, but scouts have long believed Reimer will need to move across the diamond to first base at some point. He's not shifting down the defensive spectrum without a fight, however. "I understand it, obviously," Reimer said of that speculation. "It's fair. But I want to show that I can definitely go out there and be an elite-level defensive player." He'll get his first look at Triple-A at some point this season, but even if he performs well, it could take some injuries ahead of him on the depth chart to get Reimer a 2026 big-league debut.

Alexander signed a minor-league contract with the Astros on Tuesday.

Alexander spent nearly all of 2025 at Triple-A, slashing .254/.355/.450 across 462 total plate appearances with three organizations. He'll now begin the 2026 campaign in the Astros' farm system and is again likely to spend most of the year at Triple-A Sugar Land.

Yankees manager Aaron Boone said Wednesday that McMahon will be given some reps at shortstop during spring training in order to find out whether he can be a backup option at the position, Greg Joyce of the New York Post reports.

McMahon played three innings at shortstop for the Rockies during the 2020 season, but that's the extent of his experience at the position. In all likelihood, the Yankees would use McMahon at shortstop only in an emergency situation. The 31-year-old is slated to be the team's primary third baseman against right-handed pitching.

Mets manager Carlos Mendoza said Tuesday that Baty will be eased into spring training action after experiencing hamstring discomfort during offseason workout two weeks ago, Mike Puma of the New York Post reports.

It doesn't sound like an overly serious issue for Baty, but the Mets are going to bring him along slowly early in camp. Baty figures to have a chance to beat out top prospect Carson Benge for the starting job in right field this spring, but if he doesn't, Baty is still projected to see plenty of playing time around the diamond in a utility role in 2026.

Riley didn't have any limitations this offseason and worked with Atlanta hitting coach Tim Hyers on finding his old swing, Mark Bowman of MLB.com reports.

The third baseman underwent sports hernia surgery in early August that ended his 2025 campaign prematurely, but he was fully recovered in time to get back to his normal offseason routine. That's a marked contrast to the previous offseason, when hand surgery left Riley in a cast until January and had him playing catchup during spring training. While he missed a total of 112 regular-season games over the prior two seasons, Riley appears to be in good shape to regain the form that saw him average 36 homers, 99 RBI and 159.3 games played from 2021-23.
