McNeil (shoulder) started at second base and went 1-for-1 with a walk in Sunday's Cactus League loss to the Guardians.

McNeil suited up for the first time as a member of the Athletics and reached base in both plate appearances, though he also committed a fielding error before being lifted Sunday. The veteran underwent thoracic outlet surgery shortly after the conclusion of the 2025 season, so his early participation in spring is an encouraging sign. The 33-year-old hit .243/.335/.411 with 21 doubles, 12 home runs and 54 RBI across 122 regular-season games with the Mets last year and will look to produce for his new club in 2026, likely entrenched at second base to open the campaign.

Caballero did some training at Driveline Baseball this offseason, where he focused on increasing his bat speed, Chris Kirschner and Brendan Kuty of The Athletic report.

Caballero's goal is to get his average bat speed up to 71 mph this season, which is a bit below the league average of 71.7 mph but would be a notable jump from his 69.1 mph average in 2025. The super utility player went deep in Grapefruit League action Sunday against the Mets and believes reaching double digits in home runs in 2026 is a reasonable goal, per Kuty. That would be a career high for Caballero, who popped nine homers in 2024 and five in 2025. The 29-year-old is slated to open the upcoming season as the Yankees' everyday shortstop while Anthony Volpe (shoulder) recovers.

Pirates director of sports medicine Todd Tomczyk said Monday that Simon (shoulder) is projected to return to game competition in late March or early April, Kevin Gorman of TribLive.com reports.

According to Tomczyk, Simon is "doing very well" four-plus months after undergoing surgery on his left shoulder. The 25-year-old has been taking swings in the batting cage without restrictions so far in camp, and he's set to take another step forward next week, when he's scheduled to face live pitching in batting practice. However, because Simon won't be game-ready until late March, he would appear to be firmly out of the mix for a spot on the Pirates' Opening Day roster.

Helman (groin/hip) started in left field and went 0-for-1 with a strikeout Sunday in the Rangers' 9-5 win over the Rockies in Cactus League play.

Helman had been scheduled to make his second start of the spring Saturday against the Cubs, but he was scratched from the lineup due to injury. The groin/hip issue was evidently a minor concern, given that the Rangers felt comfortable reinserting him into the lineup a day later. Helman will be competing for a utility job with the Rangers throughout the spring and could be deployed in the short side of a platoon if he ends up making Texas' Opening Day roster.

Estrada signed a minor-league contract with the Orioles on Monday that includes an invite to big-league spring training, Roch Kubatko of MASNSports.com reports.

Baltimore already acquired Blaze Alexander to help offset the injuries to Jordan Westburg (elbow) and Jackson Holliday (hand), and now Estrada will enter the fray as well. Estrada, 30, hit .253/.385/.370 with three home runs in 39 games with the Rockies last year. His 2025 season ended in August due to a hamstring strain.

Eeles left Sunday's spring training game against the Tigers due to left shoulder discomfort, Matt Weyrich of The Baltimore Sun reports.

Eeles suffered the injury on a collision with teammate Enrique Bradfield in the outfield. Eeles is aiming to earn a bench spot on the big-league roster, so this injury certainly won't help his cause if it forces him to miss additional time. He can be considered day-to-day moving forward.

Mauricio went 0-for-2 with a stolen base in the Mets' Grapefruit League opener against the Marlins on Saturday.

After reaching on a throwing error by Connor Norby in the second inning, Mauricio promptly swiped second base. It was an encouraging sign for the 24-year-old infielder. Prior to missing the entire 2024 season after ACL surgery, Mauricio had gone 31-for-38 on the basepaths over 142 games in 2023 split between Triple-A Syracuse and the majors, and per Statcast he recorded a sprint speed in the 60th percentile. In his return last season, he went just 4-for-4 in 61 big-league games on steal attempts with a 15th percentile sprint speed. If Mauricio has regained his wheels and is more confident in the health of his knee a year further removed from surgery, he could make a surprising impact in the SB category if he's able to earn consistent playing time.

McNeil (shoulder) will start at second base and bat sixth in Sunday's Cactus League game against the Guardians, Martin Gallegos of MLB.com reports.

McNeil will don an Athletics uniform for the first time after coming over from the Mets in a December trade. He underwent thoracic outlet surgery shortly after the conclusion of the 2025 regular season, with his agent later saying that the issue caused McNeil discomfort when he swung the bat late in the campaign. Entering his age-34 season, he figures to benefit from a big park upgrade moving from Queens to Sacramento.

Cardinals president of baseball operations Chaim Bloom said Saturday after the signing of Ramon Urias that the roster addition wouldn't "get in the way, substantively, for the opportunities for (Gorman)," Derrick Goold of the St. Louis Post-Dispatch reports.

The 25-year-old infielder is in line to be the team's primary third baseman in 2026, and that won't change even after Urias was brought aboard. Urias does offer a short-side platoon partner for the lefty-swinging Gorman and is also a superior defender, so he'll get reps versus lefties and could handle third base while Gorman is used at designated hitter. Gorman is looking to bounce back from a two-year drought at the plate, having slashed just .204/.284/.385 with a 35.7 percent strikeout rate over that stretch.

Sosa does not have a set defensive home entering the 2026 season and is on the White Sox's roster bubble, Mark Gonzales of the Chicago Sun-Times reports.

Sosa started 99 games at second base and 42 at first base for the White Sox in 2025, and he was an exactly league-average hitter with a 100 wRC+ across 544 plate appearances. However, the emergence of Chase Meidroth and the signing of Munetaka Murakami will push Sosa out of those roles entering 2026. Also hurting Sosa is his lack of defensive value at any position, as he registered minus-10 defensive runs saved at second last season. Sosa is out of minor-league options.
