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.

The Nationals placed Schultz on the 15-day injured list Monday due to right elbow inflammation.

Schultz didn't pitch in a Grapefruit League game after Feb. 28 due to his elbow injury, which is severe enough for him to open the season on the injured list. The earliest he can be activated from the IL is early April, but the Nationals have not indicated when the 28-year-old right-hander will embark on a rehab assignment.

Rangers manager Skip Schumaker said Monday that he's comfortable with Martin and Robert Garcia in the closer role, and who he uses in the ninth inning will "depend on the situation," Shawn McFarland of The Dallas Morning News reports.

Schumaker at the start of Rangers camp named Garcia and Martin as the favorites to garner save chances, and he still sees the situation the same way on the precipice of Opening Day. The 39-year-old Martin has never had more than four saves in a single season in his career, but he's been one of the most reliable relievers in baseball over the last four years with a 2.60 ERA, 27.4 percent strikeout rate and 3.1 percent walk rate.

Rangers manager Skip Schumaker said Monday that the team's closer job will "depend on the situation," but he's comfortable with Garcia and Chris Martin in the role, Shawn McFarland of The Dallas Morning News reports.

Schumaker said something similar at the beginning of spring training and what occurred in Cactus League play doesn't appear to have changed his mind. Garcia tied for the team lead with nine saves last season and finished with a 2.95 ERA and 68:22 K:BB across 64 innings. Neither the left-handed Garcia nor the right-handed Martin have notable splits in their careers, so it could be a situation where Schumaker rides the hot hand.

The Tigers placed Brieske (groin) on the 60-day injured list Monday.

Brieske suffered a left adductor strain during a workout last week and will now be shelved until at least late May. Putting Brieske on the 60-day IL frees up a spot on the 40-man roster for the addition of Connor Seabold.

Detroit signed Seabold to a one-year, split major-league contract Monday.

After being cut by Toronto over the weekend, Seabold quickly found an opportunity in a new organization. The 30-year-old righty may end up opening the season at Triple-A Toledo, but he'll claim a spot on the Tigers' 40-man roster and will earn a prorated $800,000 at the big-league level. Detroit cleared room on the 40-man roster for Seabold by placing Beau Brieske (adductor) on the 60-day injured list.

Schultz has been contending with right elbow discomfort of late and is expected to be placed on the injured list prior to Thursday's season opener versus the Cubs, Mark Zuckerman of NatsJournal.com reports.

The elbow injury explains why Schultz hadn't made any Grapefruit League appearances since Feb. 28. Schultz had been enjoying a strong spring prior to missing time with the injury, but with a trip to the shelf on tap to begin the season, he'll likely be eased back in as a low-leverage reliever once he's deemed ready to make his 2026 debut. The Nationals haven't provided a timeline for when Schultz might be ready to embark on a minor-league rehab assignment.

President of baseball operations Chris Young said Monday that Latz will be part of the bullpen on the Rangers' Opening Day roster, Jeff Wilson of AllDLLS.com reports.

Latz will likely be ticketed for a multi-inning relief role, with most of his opportunities expected to come in lower-leverage spots. The assignment to the bullpen is a disappointing outcome for Latz, who looked to have a leg up on Kumar Rocker for the final spot in the season-opening rotation heading into spring training based on his strong close to the 2025 campaign. After an Aug. 20 call-up from Triple-A Round Rock, Latz turned in a 2.10 ERA, 1.07 WHIP and 24:10 K:BB in 30 innings over his final eight outings with the Rangers, but he couldn't carry over that success to the spring. He yielded 16 runs (14 earned) on 18 hits and eight walks over his 15.1 innings during the Cactus League.

The Blue Jays reassigned Mantiply to minor-league camp Monday.

Mantiply is expected to open the season at Triple-A Buffalo after he was one of six non-roster invitees reassigned Monday in the Blue Jays' latest round of cuts. The 35-year-old lefty made 10 relief appearances in the majors with the Diamondbacks last season, logging a 15.83 ERA, 3.00 WHIP and 8:3 K:BB across 9.2 innings.
