The Athletics announced Monday that Muncy (hand) has begun a hitting progression, Martin Gallegos of MLB.com reports.

The rookie infielder is finally ready to start hitting again after being sidelined since late July with a hairline fracture at the base of the fourth metacarpal in his right hand. Muncy will need time to ramp back up and will likely require a rehab stint before being activated from the 10-day injured list.

Arenado (shoulder) will begin a throwing program this week, Katie Woo of The Athletic reports.

Arenado recently resumed hitting and will continue to ramp up his rehab with some throwing later this week. The veteran third baseman is working his way back from a right shoulder strain, and there is no timetable for his return to the Cardinals' active roster. Nolan Gorman will continue to serve as the team's primary option at the hot corner while Arenado is away.

Orioles interim manager Tony Mansolino said Monday that Westburg (ankle) will not be ready for activation from the 10-day injured list when first eligible Friday, Danielle Allentuck of TheBaltimoreBanner.com reports.

The Orioles have a road trip that runs through Sept. 3, and Westburg isn't expected to be available at any point during that trip. He might be ready to rejoin the team for the start of a homestand Sept. 5, but that will depend on how he progresses over the next several days. According to Matt Weyrich of The Baltimore Sun, Mansolino said that Westburg was able to do some sprinting on the field Monday, but is still "ginger" while running. The Orioles have been using a combination of Luis Vazquez, Vimael Machin and Jeremiah Jackson at third base since Westburg went down with the right ankle sprain last week.

House is out of the lineup for Monday's game against the Yankees, Andrew Golden of The Washington Post reports.

House will rest after he started at third base in each of the Nationals' last four contests while going 5-for-15 with two doubles, two RBI and three runs. Paul DeJong will check in for him at the hot corner Monday.

Sanoja is out of the lineup for Monday's game against Atlanta.

Maximo Acosta will get the nod at third base Monday in place of Sanoja, who went 6-for-15 with a home run, a double, a walk, a stolen base, four RBI and three runs while starting in each of the previous four games. Until Miami gets one of Connor Norby (wrist) or Graham Pauley (oblique) back from the injured list, Sanoja looks primed to serve as the Marlins' top option at the hot corner.

Barger is not in the lineup for Monday's game against the Twins.

Barger is not dealing with any known injury, so his absence from the lineup for a second straight day appears to be a bit of a reset as he battles through a 5-for-38 slump at the dish. Nathan Lukes will start in right field and bat second for the Blue Jays on Monday.

Baty is out of the lineup for Monday's game against the Phillies.

The left-handed-hitting Baty had started in each of the Mets' last eight games -- including two against left-handed pitchers -- but he'll hit the bench Monday while the Phillies send southpaw Cristopher Sanchez to the bump. Though the Mets could continue to be selective about using Baty versus lefties, the 25-year-old is one of the hottest hitters in the lineup and appears to have solidified himself as a mainstay in the starting nine against righties. Since the beginning of August, Baty is slashing a sizzling .321/.390/.566 with four home runs and one stolen base in 16 games.

Chapman went 1-for-4 with a double and a run scored in Sunday's 4-3 win over the Brewers.

Chapman doubled in the ninth inning before coming around to score the game-tying run. In two outings since returning from a minimum stay on the 10-day injured list due to right hand inflammation, the third baseman has tallied two runs scored, two walks, a double and a stolen base across nine plate appearances. Overall, he's slashing .227/.337/.420 with 55 runs scored, 44 RBI, 16 home runs, 16 doubles and eight stolen bases in 412 plate appearances this season.

Garcia went 2-for-4 with a solo home run, an additional run scored and a walk in Sunday's 10-8 win over the Tigers.

Garcia provided insurance in the seventh inning with a solo homer off Brenan Hanifee, his 13th long ball of the year, to push the Royals' lead to three runs. The third baseman has been swinging a hot bat lately, notching multi-hit efforts in three of his past seven games and eight times in 22 contests this month. With Sunday's production, the 25-year-old is now batting .300 on the season with 32 doubles, five triples, 13 homers, 58 RBI, 22 steals and an .832 OPS across 129 games.

Caminero went 1-for-4 with a grand slam during Sunday's 7-2 win over the Cardinals.

Caminero broke Sunday's game open with his fifth-inning grand slam off Matt Svanson. It was the third baseman's second grand slam of his career. The long ball was his 10th of August, putting him in a three-way tie with Shea Langeliers and Vinnie Pasquantino for the most round-trippers in MLB this month. He's 21-for-78 (.269) with 20 RBI and 15 runs scored during that stretch.
