Duran is out of the lineup for Monday's game against the Brewers, Tim Healey of The Boston Globe reports.

He'll take a seat for the second time in the Red Sox's first 10 games of the season as manager Alex Cora makes room in the lineup for Masataka Yoshida, who will serve as Boston's designated hitter in the series opener. Duran is one of multiple Boston hitters who has yet to get going at the dish amid the team's 2-7 start to the season; he's mustered a .200/.314/.267 slash line with zero home runs and two stolen bases over his 35 plate appearances.

The Cubs placed Boyd on the 15-day injured list Monday with a left bicep strain, Meghan Montemurro of the Chicago Tribune reports.

Boyd didn't suffer the injury at any one time but was having trouble bouncing back in between starts. The left-hander expects his absence to be a brief one. It's another blow to a Cubs rotation that also recently lose Cade Horton (forearm) to an arm injury. Javier Assad will start Tuesday versus the Rays in Boyd's place.

The Astros designated Munoz for assignment Monday.

A Rule 5 selection over the winter, Munoz won a spot in the Houston bullpen coming out of spring training but will wind up losing his spot on the 40-man roster less than two weeks into the season after yielding seven earned runs over four innings across three appearances. Assuming he clears waivers, Houston will need to offer the 25-year-old righty back to Cincinnati.

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.
