The Cubs recalled Assad from Triple-A Iowa on Monday and will have him start Tuesday's game at Tampa Bay, Sahadev Sharma of The Athletic reports.

With Matthew Boyd (biceps) and Cade Horton (forearm) landing on the injured list within the past two days, the Cubs will turn to Assad to fill one of the two openings in the rotation. After falling short in his bid for a spot on the Cubs' Opening Day roster, Assad has made two starts for Iowa this season, giving up seven earned runs on 14 hits and six walks while striking out seven over seven innings. The right-hander has a much stronger track record over parts of four seasons in the majors, accruing a 3.43 ERA, 1.33 WHIP and 9.6 K-BB% over 331 innings.

The Marlins recalled Gusto from Triple-A Jacksonville on Monday.

He'll join the 26-man active roster as a replacement in the bullpen for right-hander Pete Fairbanks, who was placed on the paternity list. Gusto collected a 5.67 ERA over 17 starts and 10 relief appearances in 2025 between the Astros and Marlins. He went five innings in his lone start with Jacksonville this season and will give the Miami bullpen some length.

The Marlins placed Fairbanks on the paternity leave list Monday.

The transaction was anticipated, as Fairbanks was used as an opener in Sunday's 7-6 win over the Yankees so that he could leave the team sooner in order to be with his growing family. Fairbanks will likely rejoin the active roster for Thursday's game against the Reds. Anthony Bender picked up a save Sunday and could get more chances this week while Fairbanks is away. Calvin Faucher and Andrew Nardi are also candidates to see save chances.

Amaya will start at designated hitter and bat ninth in Monday's game against the Rays.

Amaya will remain in the lineup for the fifth time in six games, with three of his starts coming versus lefties and two coming against righties during that stretch. The 27-year-old has gone 5-for-12 with a pair of extra-base hits to begin the season, and his hot start appears to have helped him at least temporarily supplant Moises Ballesteros as the Cubs' preferred option at DH.

Fortes will start at catcher and bat sixth in Monday's game against the Cubs, Ryan Bass of Rays.tv reports.

After taking a seat in favor of Hunter Feduccia in both of the Rays' previous two games, Fortes will be back behind the dish Monday in the team's home opener. Fortes has been the more productive of the Rays' two catchers in the early going, producing a .967 OPS over 27 plate appearances.

Palacios is out of the lineup for Monday's game against the Cubs, Ryan Bass of Rays.tv reports.

Even with Gavin Lux (shoulder) on the shelf to begin the season, the left-handed-hitting Palacios hasn't been able to take control of a strong-side platoon role at second base. The Rays have instead opted for more of a timeshare at the keystone between Palacios and Ben Williamson, who gets the nod for Monday's home opener. Palacios has now been left out of the starting nine in three of the Rays' last six matchups with right-handed pitchers.

Williamson will start at second base and bat eighth in Monday's game against the Cubs, Ryan Bass of Rays.tv reports.

After being activated from the injured list, Taylor Walls (oblique) will cover shortstop in the Rays' home opener, but Williamson will remain in the lineup for a seventh straight game while shifting over to the keystone. Through his first nine games with the Rays, Williamson is hitting .281, but he's not offering much aid in other categories (zero home runs, one steal, seven runs and three RBI). Even so, Williamson's slick fielding and ability to hit for contact may be enough for him to stick around in a near-everyday role in the Tampa Bay middle infield.

The Orioles placed Enns on the 15-day injured list Monday with a left foot infection.

The injury shouldn't require Enns to miss more than the minimum 15 days. Taking Enns' spot on the roster will be Brandon Young, who was called up from Triple-A Norfolk to serve as the Orioles' starting pitcher in Monday's game versus the White Sox.

The Orioles recalled Young from Triple-A Norfolk on Monday.

Young will be the starting pitcher for Monday's game against the White Sox, filling in for the injured Zach Eflin (elbow). The right-hander really struggled in 12 starts for the Orioles in 2025, finishing with a 6.24 ERA and 47:22 K:BB over 57.2 innings. Young could earn an additional start this weekend against the Giants if he pitches well, though Dean Kremer is a likelier option to fill that slot.

McArthur (elbow) is expected to resume a throwing program Monday, MLB.com reports.

McArthur has yet to pitch in a game since he underwent surgery following the 2024 season to address an olecranon fracture in his right elbow. He required another procedure last July to remove screws from his elbow and was expected to be ready to go for the start of spring training, but he needed to be shut down again after experiencing inflammation in the elbow. The Royals have characterized McArthur's setback as minor, and though he'll start throwing again this week, he's expected to be eased along slowly in his rehab program. The reliever appears unlikely to be ready to return from the injured list until at least May.
