O'Hearn is not in the lineup for Monday's game versus the Rangers.

O'Hearn has now been absent from the lineup seven of the last eight times the Orioles have faced a traditional left-handed starter, as he now appears firmly on the long side of a platoon. Coby Mayo will start at first base and Gary Sanchez will be the designated hitter in Monday's series opener.

Blue Jays general manager Ross Atkins said Monday that Santander (shoulder) is "nearing" the start of a hitting progression, Shi Davidi of Sportsnet.ca reports.

Atkins also revealed that Santander suffered a subluxation -- which is a partial dislocation -- when he initially injured his left shoulder back in early May. Previously, the injury was identified merely as inflammation. The Blue Jays have been waiting until Santander is symptom-free before clearing him to ramp up his hitting, and that time could be coming soon. According to Ben Nicholson-Smith of Sportsnet.ca, the Blue Jays aren't yet ruling Santander out from being activated from the injured list before the All-Star break, though a second-half return is probably more realistic at this time.

Keith, who has been playing more at third base recently, could stick at the position more permanently, with Matt Vierling also mixing in, Cody Stavenhagen of The Athletic reports.

Keith has now made six career starts at the hot corner, all of which have come this month. The 23-year-old was originally destined to play at first and second base this season, but shifting over to third has allowed him to stay in the lineup while also finding time for Spencer Torkelson and Gleyber Torres across the diamond. The Tigers pursued Alex Bregman in the offseason to handle the position, though it seems like the team may be content with Keith as the primary option now, at least against righties. Vierling, who recently returned from the injured list after missing time due to a shoulder injury, figures to see more playing time when a lefty is starting, giving Keith's left-handed bat a break.

Larnach is out of the lineup for Sunday's game against the Tigers.

Larnach had started in each of the Twins' last seven games, but he'll take a seat along with fellow left-handed hitters Matt Wallner and Kody Clemens while Minnesota adds more right-handed bats to the lineup to counter Tigers left-hander Tarik Skubal. With Larnach and Wallner on the bench, Ryan Jeffers will get a day off from catching to serve as the Twins' designated hitter, and Harrison Bader and Willi Castro will pick up starts at the corner-outfield spots.

Trout is not in the lineup for Sunday's game versus the Nationals, Jeff Fletcher of The Orange County Register reports.

It's likely just a standard rest day for Trout, who started the previous 24 games and posted an .830 OPS with four homers, 11 RBI, 13 runs and a 22:29 BB:K during that stretch. Travis d'Arnaud will receive a turn at designated hitter in the series finale against Washington.

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

Polanco is batting .143 (5-for-35) across his past 10 contests and will sit Sunday for a second straight game. Cal Raleigh will rest his legs as the designated hitter while Mitch Garver (jaw) receives a start behind the plate.

Astros general manager Dana Brown said Sunday that Alvarez (hand) has a chance to return from the 10-day injured list for next weekend's series against the Dodgers, though Brown added that is "not the most likely scenario," Chandler Rome of The Athletic reports.

Alvarez has been ramping up his swinging recently and will report to the Astros' spring facility in Florida this week to face live pitching, per Brian McTaggart of MLB.com. The veteran slugger appears to be closing in on his return from the IL, with next weekend's three-game series in Los Angeles being an unlikely best-case scenario for his activation.

Stanton is out of the lineup for Sunday's game against the Athletics.

Stanton had served as the Yankees' designated hitter for each of the previous three games, marking the first time since being activated from the 60-day injured list June 16 that he had started more than two contests in a row. He'll be back on the bench Sunday, and Stanton could continue to get at least two or three games off per week if he's unable to get going at the dish. After returning from the IL with a pair of two-hit performances, Stanton has gone 4-for-26 with no extra-base hits and a 4:10 BB:K over his subsequent eight contests.

Ohtani allowed one hit and issued one walk while striking out one batter over two scoreless innings in a no-decision against the Royals on Saturday. He also went 0-for-4 with three strikeouts as a batter.

While Ohtani didn't have his highest pitch count of the campaign -- his 27 pitches Saturday were one fewer than he accumulated during his season debut on the mound June 16 -- he took another step forward by tossing more than one inning for the first time as a Dodger. The two-way star also made a strong statement about how far he's come in his recovery from Tommy John surgery by pumping in a 101.7 mph fastball -- the fastest of his career. Ohtani now was three starts under his belt as a pitcher this season, allowing one run on three hits with a 3:1 K:BB over four innings. He'll likely continue to build up gradually, so fantasy managers should still view him as an opener during his turns in the rotation until he gets a longer leash to pitch deeper into games.

Manzardo is out of the lineup for Sunday's game against the Cardinals.

With southpaw Matthew Liberatore on the bump for the Cardinals, Manzardo will join fellow left-handed hitters Bo Naylor, Daniel Schneemann and Nolan Jones on the bench. David Fry will replace Manzardo as the Guardians' designated hitter.
