The Astros informed Lambert on Sunday that he won't be included on the Opening Day roster, Chandler Rome of The Athletic reports.

Lambert had attended spring training as a non-roster invitee but made a spirited bid for a spot in Houston's bullpen by turning in a 2.92 ERA and 8:5 K:BB in 12.1 innings during the Grapefruit League. The right-hander's minor-league contract contains an opt-out clause that will allow him to pursue opportunities elsewhere, but Lambert is still deciding whether to become a free agent or stay in the organization and report to Triple-A Sugar Land, per Rome.

The Yankees acquired Linan from the Nationals on Sunday in exchange for infielder Jorbit Vivas.

Vivas wasn't in line to make the Opening Day roster and was out of minor-league options, so the Yankees opted to cash him in for an intriguing young arm in Linan. The 21-year-old right-hander spent time at three levels between the Dodgers and Nationals organizations in 2025, logging a 3.03 ERA, 1.13 WHIP and 106:33 K:BB in 77.1 innings. With his new organization, Linan is likely to open the 2026 campaign at either Double-A Somerset or High-A Hudson Valley.

Orioles manager Craig Albernaz said Sunday that Akin (adductor) is scheduled to undergo an MRI on Monday, Roch Kubatko of MASNSports.com reports.

The MRI should provide more information on the extent of the adductor injury that Akin suffered while warming up in the bullpen Saturday and will help the Orioles determine whether or not the lefty requires a stint on the injured list to begin the season. If Akin ends up being shelved, it could open the door for Grant Wolfram to make the Opening Day roster as another southpaw option out of the bullpen.

Gamboa (elbow) recorded two outs via strikeout and allowed one earned run on three hits in his relief appearance Friday in the Red Sox's 2-0 win over the Rays.

Gamboa made just his second appearance of the Grapefruit League and his first since Feb. 28 after he was briefly shut down due to a left elbow issue. The injury prevented Gamboa from staking a claim to a spot in the Opening Day bullpen, as the Red Sox reassigned him to minor-league camp Saturday.

The Guardians selected Heuer's contract to the major-league roster Sunday and optioned him to Triple-A Columbus.

The 29-year-old righty joined Cleveland as a non-roster invitee in December and grabbed a place on the 40-man roster despite giving up eight runs with an 11:5 K:BB over eight innings during spring training. Heuer made three MLB appearances last season after being sidelined the previous four years due to injuries, and he'll likely need to pitch well for Columbus to get another look in the big leagues.

Kolek (oblique) threw a bullpen Saturday and could pitch in minor-league games next week, MLB.com reports.

Kolek is gradually building back up as he recovers from the Grade 1 left oblique strain he suffered Feb. 25, logging bullpen sessions Wednesday and Saturday. The right-hander is making progress, but it remains likely he opens the season on the injured list before reporting to Triple-A Omaha.

Crochet allowed six runs on six hits and two walks while striking out three over 5.1 innings in Saturday's spring start against Atlanta.

Crochet finished the Grapefruit League with an unsightly 7.36 ERA over 14.2 innings. Both the pitcher and Boston manager Alex Cora downplayed the spring results to Chris Cotillo of MassLive.com. Crochet attributed Saturday's line to missed locations and tinkering with a pitch mix he would normally avoid in a more competitive environment. The left-hander is set to pitch Opening Day on the road against the Reds.

De Los Santos (knee) struck out a batter and allowed one walk and no hits over a scoreless inning of relief Friday in the Astros' 7-4 loss to the Marlins in Grapefruit League play.

The reliever made his spring debut after completing his recovery from the right knee strain he suffered early in camp. Manager Joe Espada told Brian McTaggart of MLB.com that De Los Santos is scheduled to pitch again Monday in an exhibition against Triple-A Sugar Land. If all goes well in that outing, De Los Santos should be able to secure a spot in the Opening Day bullpen.

Texas manager Skip Schumaker said Saturday that Latz's chances of earning a roster spot will not be affected by the results of his final spring start, Kennedi Landry of MLB.com reports.

Latz allowed nine runs on eight hits and two walks over three innings in a Cactus League outing Thursday, inflating his spring ERA to 8.22. "You don't make or break a team or a position on the last day of spring, or last couple days of spring," Schumaker said of Latz. The Rangers' main concern is the southpaw's inability to maintain velocity deeper into games this spring, which could prevent him from providing at least five effective innings in a start. Latz's main competition for the final spot in the rotation is Kumar Rocker, who has excelled his last two times out but still has things the organization would like him to work on, such as his changeup usage. Non-roster veterans Austin Gomber and Cal Quantrill are also still in the mix.

Akin suffered an adductor injury while warming up in the bullpen during Baltimore's Grapefruit League game against the Phillies on Saturday, Jake Rill of MLB.com reports.

Manager Craig Albernaz said after the game that he doesn't know how severe Akin's injury is, but the skipper kept him out of the game as a precaution. More information on the 30-year-old's status for Opening Day should be available in the next couple days.
