Karros went 2-for-4 with two runs scored Tuesday against the Astros.

Karros was briefly sidelined with a back injury but returned to the lineup Friday and has started four straight games since -- all of which have come on the road. He's gone 5-for-13 while hitting primarily in the bottom third of the lineup.

Gorman went 1-for-4 with a two-run homer in Tuesday's loss to the Pirates.

Gorman had one of just three hits for the Cardinals on the evening with his being a big fly in the fourth inning to get them on the scoreboard. Gorman's now driven in four runs over his last three games and has hit safely in five straight while reaching base safely 10 times over that span, registering a 4:4 BB:K.

Marte started in center field and went 1-for-4 in Tuesday's 6-3 loss to the Dodgers.

Marte, who transitioned from third base to right field midseason, made his first career start in the center field. Unfortunately for the Reds, it showed in the sixth inning when Marte misjudged a flyball that sailed over his head for a two-run double. He was later moved to right field, which has been his home on the diamond for the last month.

Chapman went 1-for-3 with a two-run home run, a walk and a stolen base in Tuesday's 5-2 win over the Cubs.

Chapman has gone 2-for-10 with a pair of extra-base hits and two steals since returning from a bout of hand inflammation. The third baseman hadn't homered since he went yard twice versus the Mets on July 27. Chapman is slashing .228/.339/.428 with 17 homers, 46 RBI, 56 runs scored and nine stolen bases through 99 contests this season.

Double-A Biloxi activated Wilken (knee) from its 7-day injured list Tuesday.

Wilken has been sidelined since late June with a dislocated left kneecap, which he sustained during the celebration of Biloxi's first-half championship. The 23-year-old slugged 18 home runs in 65 games with Biloxi before getting injured, though his production came with a .230 average and 26.1 percent strikeout rate.

Muncy (oblique) is expected to face live pitching Tuesday, David Vassegh of AM 570 LA Sports reports.

Muncy started to take swings off a tee last week, and he will now progress to facing real pitching. The 35-year-old was placed on the 10-day injured list Aug. 15 due to a right oblique strain, so he's eligible to return to action at any point. Manager Dave Roberts said Monday that Muncy could be activated during the team's upcoming road trip, which begins next Tuesday in Pittsburgh.

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.

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.

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.
