De Jesus, who was recently added to Detroit's 40-man roster, seems likely to secure an Opening Day bullpen role, Jason Beck of MLB.com reports.

De Jesus looked good for Team Venezuela in the World Baseball Classic, and Detroit was impressed enough to add the non-roster invitee to its 40-man roster. That move seems to suggest that the 29-year-old lefty will ultimately make the Opening Day roster, though nothing has been made official yet. De Jesus pitched briefly in the majors back in 2023 and has spent the past few seasons in the Korea Baseball Organization.

Arizona optioned Garcia to Triple-A Reno on Monday.

With the move now official, the Diamondbacks will begin the 2026 campaign without a lefty in their bullpen. Garcia struggled to find the strike zone during his spring training appearances, as shown by seven walks in 6.1 innings. He'll need to shift his focus to pounding the zone at Triple-A if he wants to earn a place on the big-league roster.

Curvelo was optioned to Triple-A Round Rock on Monday.

Curvelo struggled to a 5.68 ERA and 1.42 WHIP over 19.0 innings a season ago in the big leagues, and he wasn't able to show enough during spring training to secure a place in the Rangers' bullpen. He fared better at Triple-A in 2025, posting a 3.76 ERA and 1.32 WHIP with a 41:19 K:BB over 40.2 frames.

The Tigers announced Monday that Seabold will be listed on the Opening Day roster, Evan Petzold of the Detroit Free Press reports.

Seabold agreed to a split major-league contract with the Tigers earlier Monday, and it didn't take long for the club to confirm that the right-hander will start the year in the major leagues. The 30-year-old is presumably in line for low-leverage opportunities with his new squad after working to a 4.35 ERA in 10.1 innings during stops in Tampa Bay and Atlanta a season ago. "We're happy to add him," said manager A.J. Hinch, per Petzold. "We really like the adjustment that he made, with both his stuff and the way his pitches are interacting. As his stuff improved, he got a ton of swing-and-miss this spring."

Moran has secured a place on Boston's Opening Day roster, Ari Alexander of 7 News Boston reports.

Moran fared well in limited spring action, as he tossed 2.2 scoreless frames and struck out three in three appearances. The southpaw is out of minor-league options, which may have factored into Boston's decision to name him to the Opening Day roster. Moran pitched in two games a season ago for the Red Sox, allowing three runs on five hits and three walks while striking out five over four innings of relief work.

Padres manager Craig Stammen said Monday that Adam (quadriceps) will begin the season on the injured list, Kevin Acee of The San Diego Union-Tribune reports.

Coming back from surgery last September to repair a ruptured left quadriceps tendon, Adam has retired all six batters he's faced this spring. However, Stammen said Monday that the club has "got to be smart" with Adam, who should make his season debut "sometime in April, most likely." Once deemed ready, Adam is slated to fill a setup role in front of closer Mason Miller.

The Rockies released Brebbia on Monday.

Brebbia joined the Rockies in early December on an NRI deal. He entered spring training with a decent shot at making the team's Opening Day roster but struggled across seven Cactus League games, allowing seven runs on nine hits while striking out 11 across nine innings. The 35-year-old will look to join a team looking to add a southpaw to its bullpen.

The Red Sox reassigned Kahnle to minor-league camp Monday.

Kahnle agreed to a minor-league contract with the Red Sox on Tuesday. It looked like the veteran right-hander had a decent shot at making the team's Opening Day roster as a member of bullpen, but that won't be the case after being reassigned Monday. Kahnle has no minor-league options left, so it's unclear whether he'll stay with Boston or request a release and try his luck elsewhere.

The Red Sox optioned Kelly to minor-league camp Monday.

Kelly was gunning for a spot on Boston's Opening Day roster after appearing in 28 major-league games for the club in 2025, finishing with a 4.58 ERA, 1.33 WHIP, three holds and a 35:12 K:BB across 35.1 innings. The 31-year-old right-hander will likely start out in Triple-A Worcester but would be in line for a call-up to the majors when the Red Sox need more depth out of the bullpen.

The Nationals selected Perez's contract from Triple-A Rochester on Monday.

Perez was in Nats camp as a non-roster invitee and earned a spot on the Opening Day roster after permitted just one run with a 5:1 K:BB over six Grapefruit League frames. The 29-year-old will be the most experienced reliever on the Washington roster, which could give him a chance to see high-leverage innings.
