Casas went 2-for-4 with an RBI single and a double in Monday's 9-0 win over Oakland.

With Justin Turner now in Toronto, Casas should pick up more starts against lefty arms this season. The 24-year-old first baseman has yet to display his power upside with no home runs through five games this season, but Casas should have a chance to build off his 24-homer campaign in 2023 with the additional opportunities he projects to see.

Freeman went 3-for-4 with a double, two runs and two RBI against the Giants in an 8-3 victory Monday.

Freeman is off to a hot start to the campaign, slashing .360/.500/.520 over 32 plate appearances. He's collected a pair of three-hit performances over his past three games, though only one of the hits during that span has gone for extra bases. Freeman has driven in six runs through seven games and should get ample opportunity to produce throughout the season with Mookie Betts and Shohei Ohtani hitting ahead of him.

Steer went 2-for-5 with a double, home run, four RBI and two runs in Monday's win over the Phillies.

Steer stepped to the plate in the top of the 10th inning Monday against Connor Brogdon and hit a go-ahead 383-foot home run to give Cincinnati the lead for good. It was Steer's first career grand slam. The second-year Red looks to build upon his strong rookie campaign last season in which he slashed .271/.356/.464 with 23 home runs and 86 RBI.

Mountcastle went 2-for-4 with a home run and three RBI in Monday's win over the Royals.

Mountcastle crushed a two-run 408-foot home run off Michael Wacha in the fourth inning for his first of the season. The Orioles first baseman struggled in spring training with a .243/.256/.324 slash line and no homers, so this round-tripper was likely a welcome sight. Mountcastle will have to hit to keep his lineup spot in Baltimore with the bevy of young bats continuing to develop under general manager Mike Elias' watch.

Flores was added to the starting lineup for Monday's game against the Dodgers, Susan Slusser of the San Francisco Chronicle reports.

It appeared that Flores would be held out of Monday's contest after taking a tumble Sunday afternoon, but he worked out before the game and ultimately got the green light. He'll man first base and bat fifth.

Flores (shoulder) is not in the lineup for Monday's game against the Dodgers, Shayna Rubin of the San Francisco Chronicle reports.

Flores injured his shoulder Sunday after tumbling into the dugout trying to catch a foul ball in the first inning. Tyler Fitzgerald will draw the start at first base and bat ninth in Monday's game against Dodgers left-hander James Paxton.

Abreu (hand) will start at first base and bat sixth in Monday's game versus the Blue Jays, Matt Kawahara of the Houston Chronicle reports.

Abreu was out of the lineup Sunday due to lingering soreness in his hand as a result of a hit-by-pitch Saturday, but he's feeling well enough to give it a go Monday. The veteran first baseman has yet to pick up a base hit this season.

Sano is out of the lineup for Monday's game against the Marlins, Erica Weston of Bally Sports West reports.

Sano served as the Angels' designated hitter for the first two games of the season, but he went just 1-for-6 with four strikeouts between those contests and now finds himself on the bench for the second straight day. Given that he's signed to a modest one-year, $1 million deal and offers no defensive utility, Sano could soon find himself off the roster if he doesn't pick up the pace at the plate in the near future. For now, Sano looks like he'll be part of a committee at DH rather than a clear everyday player.

Gallo is absent from the lineup for Monday's contest against the Pirates, Andrew Golden of The Washington Post reports.

Gallo started each of the Nationals' first three contests against a right-hander, but he went 0-for-12 with six strikeouts and will now take a seat versus lefty Marco Gonzales on Monday. Joey Meneses will handle first base in Gallo's stead.

Tellez is out of the lineup for Monday's game versus the Nationals.

The Pirates are facing a fifth straight left-handed starting pitcher to begin the season, and the lefty-hitting Tellez has now been on the bench on three occasions. Connor Joe will start at first base Monday in Tellez's stead.
