The Guardians optioned Heuer to Triple-A Columbus on Monday.

Heuer will cede his spot in the bullpen and on the active roster to right-hander Shawn Armstrong (groin), who was reinstated from the 15-day injured list in a corresponding move. After being recalled from Triple-A last Wednesday, Heuer made a lone appearance during his stint in the big leagues, striking out two batters and allowing one run on three hits and one walk in two innings in Sunday's 10-3 win over the Reds.

The Guardians reinstated Armstrong (groin) from the 15-day injured list Monday.

Armstrong will be taking over the 26-man active roster and bullpen spot of right-hander Codi Heuer, who was optioned to Triple-A Columbus. Shelved since April 26 due to a right groin strain, Armstrong proved his health after making two rehab appearances with Double-A Akron last week.

The Royals recalled Morgan from Triple-A Omaha on Monday.

Morgan will be up with the Royals for his third stint in the majors of the season. Over seven appearances for Kansas City, the righty reliever has yielded three earned runs on eight hits and six walks over 10.1 innings. He's been even more dominant in his 11.1 innings with Omaha, submitting a spotless ERA and 0.63 WHIP while striking out 18 batters.

The Orioles designated Espada for assignment Monday, Roch Kubatko of MASNSports.com reports.

The righty reliever will give up his spot on Baltimore's 40-man roster to outfielder Michael Siani, whom the Orioles claimed off waivers from the Dodgers. Espada has made just one appearance at the big-league level in 2026 and struggled over 15.1 innings between Triple-A Norfolk and Double-A Chesapeake, pitching to a 5.87 ERA, 1.76 WHIP and 10:13 K:BB.

The Mets transferred Minter (lat/hip) from the 15-day injured list to the 60-day IL on Monday.

The transaction clears a spot on the 40-man roster for the addition of right-hander Daniel Duarte, who was called up from Triple-A Syracuse. The move doesn't alter Minter's timetable, as he's already spent nearly 60 days on the shelf, and his activation isn't imminent. Out all season while recovering from last year's lat surgery, Minter was pulled off his rehab assignment earlier this month because of left hip discomfort. He resumed his rehab this past Friday with a scoreless frame for Syracuse.

The Mets optioned Gerber to Triple-A Syracuse on Monday.

Gerber did not make an appearance during his most recent brief stint with the big club. His spot on the roster and in the bullpen is being absorbed by Daniel Duarte.

The Mets selected Duarte's contract from Triple-A Syracuse on Monday, Anthony DiComo of MLB.com reports.

Duarte had exercised the upward mobility clause in his contract, so the Mets either had to add him to the major-league roster or risk losing him to another organization. They chose the former after Duarte posted a 2.60 ERA and 14:9 K:BB over 17.1 innings with Syracuse. When/if Duarte makes an appearance, it will be his first at the big-league level since 2024.

Hentges picked up a hold and struck out two in a scoreless inning during Sunday's 10-1 win over the Athletics.

Hentges entered in the seventh inning and required just 10 pitches to get through the frame, throwing seven for strikes. After undergoing shoulder surgery in September 2024 and knee surgery in August 2025, the 29-year-old southpaw returned to big-league action May 10. He has turned in four scoreless outings this season, allowing one hit and three walks while striking out five in 3.1 innings.

Beeter (forearm) threw a scoreless inning for Triple-A Rochester on Saturday, allowing one hit and striking out one.

Per Spencer Nusbaum of The Athletic, Beeter will make one more rehab appearance Tuesday before potentially being activated from the IL. The right-hander should slot right back into the Nationals' unsettled high-leverage mix once he returns after posting a 3.48 ERA, 1.26 WHIP and 9:8 K:BB over 10.1 innings to begin the season with one win, two holds and two saves in 10 appearances. Beeter's been sidelined since April 21 due to forearm soreness.

Williams (3-1) picked up the win Sunday against the Yankees, walking one and striking out one in a scoreless and hitless 10th inning.

The Mets' closer left phantom runner Ryan McMahon stranded by coaxing a double play out of Austin Wells, then got rewarded with the victory when Carson Benge brought home the winning run with a fielder's choice chopper up the middle. Williams hasn't been tagged with a run in nine straight appearances, posting a 11:2 K:BB and allowing only one hit in 8.2 innings over that stretch while collecting two wins and four saves.
