The Nationals promoted Morales from Double-A Harrisburg to Triple-A Rochester on Friday.

Selected with the first pick of the second round in the 2023 First-Year Player Draft, Morales saw his 2024 campaign interrupted by a thumb injury. The 23-year-old was healthy to begin the current season and got off to a hot start with Harrisburg, slashing .315/.366/.520 with four home runs and a 23.2 percent strikeout rate over 33 games to earn the promotion. Over his first three contests with Rochester he's gone 2-for-9 with three walks against two strikeouts. Morales has split his time this season between third base and first base, but his likely home in the majors is at the latter position or at designated hitter.

Mayer started at third base and went 2-for-4 with a run scored in Sunday's 5-1 loss to Baltimore.

Mayer, who went hitless in four at-bats during his MLB debut Saturday, picked up his first hit in the majors on his first at-bat of the day. The left-handed hitter singled to the opposite field. He later pulled a double in the eighth inning and scored his first MLB run. With the Red Sox describing Alex Bregman's quadriceps injury as "significant" and "pretty severely strained," Mayer is line for regular turns at third base.

Suarez went 3-for-4 with a double, two RBI and a run scored in Sunday's loss to St. Louis.

Suarez gave Arizona an early lead with his two-run single in the first inning. He later doubled and scored a run in the sixth. It was his first game with at least three hits since belting four homers against Atlanta on April 26. Suarez has produced four multi-hit performances over his last 10 games, going 13-for-38 (.342) in the process. He's now slashing .230/.312/.503 with 24 extra-base hits and 41 RBI through 218 plate appearances.

Vargas went 2-for-4 with a solo home run, a double and an additional run scored in Sunday's 5-4 loss to the Rangers.

Vargas put the White Sox on the board with a solo homer in the fourth inning and then doubled and scored in the sixth. The 25-year-old has been swinging a hot bat lately, tallying five multi-hit efforts over his last 10 games while racking up nine extra-base hits, eight RBI and six runs scored. On the season, he's slashing .239/.316/.418 with seven home runs, 23 RBI, 23 runs scored and one steal across 206 plate appearances.

Vientos (abdomen) will start at third base and bat second Sunday against the Dodgers.

Vientos didn't start the first two games of the series due to abdominal soreness, but he'll rejoin the starting nine for Sunday's series finale. The 25-year-old has a .266/.324/.344 slash line with one home run, three RBI and seven runs through 20 games in May.

Bride will start at third base and bat fifth in Sunday's game against the Royals.

Bride has picked up starts in four of the Twins' last five games, but he still looks to be stuck in a short-side platoon role. Three of those starts have come against left-handed pitching, and his chances of earning playing time versus righties will take even more of a hit once the likes of Matt Wallner (hamstring) and Byron Buxton (concussion) return from the injured list.

Rojas is out of the lineup for Sunday's game against the Rangers.

Rojas had started each of the last six games while the White Sox opposed right-handed pitchers, but he'll hit the bench Sunday with southpaw Patrick Corbin on the bump for the Rangers. Rojas' move to the bench will open up a spot in the lineup for Vinny Capra, who will start at shortstop.

Hayes is out of the lineup for Sunday's game against the Brewers.

Hayes will be joined on the bench by Bryan Reynolds (torso) as the Pirates give two of their lineup regulars a breather for the day game after a night game. Jared Triolo will fill in for Hayes at third base.

Tena is out of the lineup for Sunday's game against the Giants, Bobby Blanco of MASNSports.com reports.

Tena will take a seat for the second day in a row while the Giants send another left-handed starting pitcher to the bump in Robbie Ray. Amed Rosario will get the nod at third base Sunday, and he and Tena will continue to work in a platoon, potentially until Paul DeJong (orbital) returns from the injured list.

Mayer went 0-for-4 with three strikeouts in the second game of Saturday's doubleheader against the Orioles.

The 22-year-old was promoted between games of the twin bill and started at third base in the nightcap, but he struck out in his first three at-bats before grounding into a fielder's choice in the ninth inning. Mayer is the organization's top infield prospect and posted a .265/.342/.465 slash line with nine homers in 43 games with Triple-A Worcester before being promoted, and he should receive plenty of playing time with the Red Sox while Alex Bregman (quadriceps) is sidelined.
