Orioles president of baseball operations Mike Elias said Wednesday that Alexander is a candidate to start at second base while Jackson Holliday (hand) is out, Matt Weyrich of The Baltimore Sun reports.

The Orioles acquired Alexander via trade Feb. 5, and the next day Holliday suffered a hamate bone fracture that will result in a stint on the injured list to begin the season. Alexander slashed .230/.323/.383 with seven homers and four steals over 74 games for the Diamondbacks in 2025. Jordan Westburg (oblique) will also be in the mix for reps at second base while Holliday is shelved.

Westburg could miss the first few Grapefruit League games after suffering a strained right oblique in late January, Roch Kubatko of MASNSports.com reports.

Oblique injuries have a tendency to linger, so the Orioles will proceed cautiously with the infielder so he doesn't suffer a setback. Westburg is projected to be the team's everyday third baseman this season, though he could fill in at second base while Jackson Holliday (hand) is sidelined to begin the campaign.

Diaz was added to the Mariners' spring training roster as a non-roster invitee.

Diaz was designated for assignment and outrighted to Triple-A in January, when the Mariners acquired Cooper Criswell. The left-hander will likely be a depth option for Seattle's bullpen this season, although he isn't guaranteed a spot on the Opening Day roster. He made just one big-league appearance in 2025.

Holliday will undergo surgery Thursday for a fractured right hamate bone and will begin the season on the injured list, Roch Kubatko of MASNSports.com reports.

A clearer timetable should become available after the operation, but Holliday will shelved for several weeks in any case. Additionally, it's a procedure that can often result in an initial loss of power for a player upon their return. Blaze Alexander and Jordan Westburg (oblique) are candidates to handle second base while Holliday is out.

Gusto (shoulder) will be available to pitch this week as spring training gets underway, Christina De Nicola of MLB.com reports.

Gusto closed the 2025 season on the Marlins' injured list after he was diagnosed with a right shoulder impingement in late August, but he was able to make a full recovery over the offseason. Between his stops with Houston and Miami last season, Gusto started 17 of his 27 appearances and posted a 5.67 ERA and 1.48 WHIP in 101.2 innings. The Marlins could have the right-hander stretch out as a starter during spring training, but he'll likely serve as more of a insurance option for the rotation and could begin the campaign as a long man out of the bullpen.

Garrett (elbow) will be available to pitch this week as spring training gets underway, Christina De Nicola of MLB.com reports.

The Marlins announced Wednesday that aside from Calvin Faucher -- who has yet to report to camp --and the rehabbing Ronny Henriquez (elbow), all pitchers on the 40-man roster are operating with no restrictions to begin camp. Garrett missed the entire 2025 season after undergoing elbow surgery with an internal brace in December 2024, but he told Kevin Barral of FishonFirst.com that he threw "a couple" live bullpen sessions prior to reporting to camp and is scheduled to throw another one Wednesday. Since he's coming off a major injury, Garrett may be eased into Grapefruit League action, but the 28-year-old lefty should have a fairly clear path to an Opening Day rotation spot.

Astros manager Joe Espada announced Wednesday that Brown will be the team's Opening Day starter, Chandler Rome of The Athletic reports.

Most teams don't reveal their Opening Day starters this early in spring training, but Brown was the obvious choice after finishing third in American League Cy Young voting in 2025. The 27-year-old right-hander will go up against the Angels at home on Opening Day.

Meyer (hip) will be available to pitch this week as spring training gets underway, Christina De Nicola of MLB.com reports.

The Marlins announced Wednesday that aside from Calvin Faucher -- who has yet to report to camp --and the rehabbing Ronny Henriquez (elbow), all pitchers on the 40-man roster are operating with no restrictions to begin camp. A healthy Meyer should have the inside track on a spot in the Opening Day rotation. The 26-year-old turned in a 4.73 ERA, 1.42 WHIP and 68:20 K:BB across 64.2 innings over 12 starts in 2025 before he was shut down with a left hip labral injury that required season-ending surgery in late June.

Astros manager Joe Espada said Wednesday that De Los Santos has been shut down due to a right knee strain, Chandler Rome of The Athletic reports.

It's unclear when De Los Santos might be cleared to throw again. The right-hander posted a 4.36 ERA and 62:24 K:BB over 66 innings between Atlanta and Houston in 2025. If healthy, De Los Santos is pegged for a middle relief role in the Astros' bullpen.

Diaz is behind schedule with his running program after suffering a left foot sprain during the Dominican Winter League, Chandler Rome of The Athletic reports.

Diaz is participating in other baseball activities and will catch Tatsuya Imai's bullpen session Wednesday, but he's a tad behind with his running. It does not sound like an injury that will sideline Diaz long, but the Astros could hold him out of the first handful of Grapefruit League games just to be safe.
