The Diamondbacks placed Locklear (elbow) on the 10-day injured list Wednesday.

Locklear was held out for the entirety of spring training while recovering from Oct. 16 surgeries to repair the labrum in his left shoulder and a torn ligament in his left elbow. He's not expected to be ready to return from IL until around mid-May to early June.

The Diamondbacks selected Vargas' contract from Triple-A Reno on Wednesday.

Vargas was able to win a spot on Diamondbacks' Opening Day roster as a utility man, beating out Jacob Amaya for one of the final spots on the Arizona bench. After slashing .270/.292/.383 with three home runs and 19 RBI over 121 plate appearances with Arizona in 2025, Vargas will likely be in store for limited playing time this season so long as Ketel Marte (lower leg), Geraldo Perdomo and Nolan Arenado are all healthy.

The Rays placed Walls on the 10-day injured list Tuesday with a right oblique strain.

Walls is slated to miss at least the first couple weeks of the season due to an oblique strain that first popped up in late February. Carson Williams will handle shortstop for the Rays while Walls is out and could keep the job if he gets off to a hot start.

The Angels selected Candelario's contract from Triple-A Salt Lake on Tuesday.

Candelario earned a spot on the Angels' Opening Day roster after slashing .245/.339/.612 with four homers, 10 RBI and eight runs scored over 56 plate appearances in the Cactus League. He will provide infield depth for the big club to begin the season while Vaughn Grissom (wrist) is on the injured list.

The Angels placed Rendon (hip) on the 60-day injured list Tuesday.

After reaching an agreement over the winter with the Angels to restructure the final year of the seven-year, $245 million contract he signed in December 2019, Rendon won't join the Angels for 2026 and will miss a second straight season after undergoing hip surgery prior to the 2025 campaign. However, he will remain on the team's official roster and presumably spend the entire season on the 60-day IL. Once he becomes a free agent following the season, Rendon is expected to formally retire from professional baseball.

The Orioles designated Ramos for assignment Tuesday.

Ramos slashed .316/.381/.474 with a homer, three RBI and four runs scored across 42 plate appearances in the Grapefruit League, but his attempt at making Baltimore's Opening Day roster was still unsuccessful. The 24-year-old doesn't have minor-league options remaining, so he'll also have to forfeit his place on the 40-man roster.

Monasterio will be part of a three-player platoon at second base early in the regular season, Chris Cotillo of MassLive.com reports.

Boston manager Alex Cora discussed his plans for second base, where Marcelo Mayer will start against right-handers. Against lefties, it will be either Monasterio or Isiah Kiner-Falefa. Monasterio was better than Kiner-Falefa against left-handers in 2025, but Cora indicated he would "mix-and-match" between the two. Fantasy managers will get an early look at how Cora handles the situation, as Boston is scheduled to face left-handers in its first two games of the regular season.

The Rockies are expected to place Freeman on the 10-day injured list Wednesday due to lower-back inflammation, Kevin Henry of The Denver Gazette reports.

Freeman didn't make his Cactus League debut until March 5 due to back problems and he encountered a setback last week. While he does not appear to have any structural damage in his back, the fact that the injury has lingered for so long could point to longer than a minimum stay on the IL. Once healthy, Freeman projects for a super-utility role in Colorado.

Chaparro is expected to begin the season as the Nationals' primary designated hitter, Jessica Camerato and Paige Leckie of MLB.com report.

Luis Garcia is shifting to first base and Daylen Lile should be the primary right fielder, leaving DH available for Chaparro. The 26-year-old hasn't done much yet in the majors to suggest he's capable of providing consistent offense, however, slashing .203/.268/.358 in 205 plate appearances for the Nats over the last two years with just five homers. He's also struggled this spring, batting .154 (6-for-39) with two home runs and a 6:12 BB:K. If Chaparro can't step up, he could be the player who loses his spot when it's time for Dylan Crews or Robert Hassell -- both of whom will begin the year with Triple-A Rochester -- to get another look.

House slashed .429/.444/.786 over 16 Grapefruit League games this spring with six doubles and three home runs.

The 22-year-old third baseman also had a 1:11 BB:K, however, creating plenty of doubt as to whether House will be able to maintain that momentum into the regular season. He's locked into the starting job at the hot corner, but he'll need to significantly improve his plate discipline to get to his power after he managed just a 2.9 percent walk rate against a 28.5 percent strikeout rate as a rookie in 2025.
