O'Hearn went 1-for-4 with a double, two RBI and a walk in Tuesday's 7-6 extra-inning loss to the Mets.

It was O'Hearn's first multi-RBI effort since June 11, and he's now logged at least one hit in six of his last eight outings. The All-Star slugger has cooled off significantly following an excellent start to the season, during which he had a .986 OPS as of May 27, but he should remain locked into the strong side of a platoon at first base with Coby Mayo while Ryan Mountcastle (hamstring) is on the shelf. Over his last 124 plate appearances (32 games), O'Hearn is slashing just .208/.306/.321 with two home runs, six doubles, 11 RBI and 14 runs scored.

The Brewers announced Tuesday that Hoskins (thumb) is hoping to return from the 10-day injured list by mid-to late-August, Curt Hogg of the Milwaukee Journal Sentinel reports.

Hoskins has a Grade 2 UCL sprain in his left thumb, an injury he suffered while applying a tag during Saturday's loss to the Marlins. Andrew Vaughn started at first base for the Brewers in Monday's win over the Dodgers and could be the primary option at the position while Hoskins is on the shelf. Jake Bauers should also be in the mix for playing time at first base.

Naylor went 1-for-2 with a two-run home run, an additional run, two walks and a stolen base in a 6-3 win against the Padres on Monday.

Naylor had the biggest hit of the game for the Diamondbacks, swatting a 413-foot, two-run homer to center field in the fifth inning to give the team a three-run lead. He also stole a base in the ninth frame, giving him 11 homers and 11 thefts on the campaign. Naylor's power has dropped a bit this season (he hit 31 long balls with Cleveland last year), but he's otherwise been an astute pickup for Arizona, as he's posted a .299/.358/.469 slash line with 58 RBI through 82 games.

Vaughn went 1-for-2 with a three-run home run, a walk and an additional run scored during Monday's 9-1 win over the Dodgers.

After Vaughn had spent the previous three weeks at Triple-A Nashville following his acquisition from the White Sox on June 13, the Brewers called up the 27-year-old first baseman from the minors to replace Rhys Hoskins (thumb) on the active roster. Vaughn entered the starting nine in his first game with Milwaukee and made an instant impact, taking Yoshinobu Yamamoto deep in the first inning and plating Sal Frelick and William Contreras to stake the Brewers to an early lead. While Vaughn's long-term role with the Brewers remains unclear, the fact that he drew the start at first base against the right-handed Yamamoto over the lefty-hitting Jake Bauers suggests that Vaughn will get a look as the team's primary option at the position while Hoskins is on the shelf.

Gonzalez went 2-for-5 with a solo homer and an additional run scored in Monday's 9-3 win against the Rockies.

Gonzalez drew his third consecutive start at the keystone and made the most of it, smashing a monstrous 454-foot solo shot off Colorado reliever Ryan Rolison for Boston's final run of the contest. Gonzalez is the short side of a platoon with David Hamilton but has been successful when in the lineup. Through 140 total plate appearances, the 28-year-old is slashing .326/.357/.566 with 25 RBI, 21 runs scored and four stolen bases.

The Dodgers placed Hernandez on the 10-day injured list Monday with left elbow inflammation.

Manager Dave Roberts said it's an injury Hernandez has dealt with for about a month, Fabian Ardaya of The Athletic reports. Because the injury is to his non-throwing elbow, Hernandez would seem to have a good chance to return when first eligible at the start of the second half.

Vaughn will start at first base and bat fifth in Monday's game versus the Dodgers.

The Brewers are throwing Vaughn right into the lineup after he took the roster spot of the injured Rhys Hoskins (thumb). While the Brewers also figure to give Jake Bauers reps at first base while Hoskins is out, it's notable that the right-handed-hitting Vaughn is getting the first shot against Dodgers right Yoshinobu Yamamoto. Vaughn was acquired via trade from the White Sox last month after he slashed .248/.303/.407 in parts of five seasons with the Pale Hose.

The White Sox placed Noda on the 10-day injured list Monday with a right quadriceps strain.

Noda suffered the injury during Sunday's loss in Colorado and will be sidelined at least until the start of the second half. Tristan Gray was called up from Triple-A Charlotte to replace Noda on the 26-man active roster.

Horwitz is out of the lineup for Monday's game against the Royals.

After starting in each of the last eight games, the left-handed-hitting Horwitz will be given the night off while the Royals send southpaw Noah Cameron to the hill for the series opener. Jared Triolo will replace Horwitz at first base and will bat eighth.

The Astros placed Walker on the paternity list Monday.

Walker will likely be away for the entirety of the Astros' three-game set against the Guardians that runs through Wednesday before rejoining the club for its weekend series versus the Rangers. Victor Caratini could see reps at first base while Walker is away.
