Cardinals manager Oliver Marmol said Wednesday that Arenado (shoulder) is in the early stages of a throwing program while rehabbing at the team's spring training complex in Florida, John Denton of MLB.com reports.

Arenado has missed all of August with a right shoulder strain and doesn't appear on track to return at the beginning of September when rosters expand. The hope remains that the veteran third baseman will make it back in action at some point this season, but until then, Nolan Gorman will continue to hold down the hot corner for the Cardinals.

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

Sanoja will hit the bench for the second time in the series and may have settled into more of a timeshare at third base with Maximo Acosta, who will replace him in the lineup Wednesday. Both Sanoja and Acosta are likely to see their opportunities to play at third base diminish once Connor Norby (wrist) completes his minor-league rehab assignment and is activated from the 10-day injured list.

DeJong is absent from the lineup for Wednesday's contest versus the Yankees.

DeJong had started six straight games against left-handed pitching, but he'll take a seat Wednesday as the Yankees send southpaw Max Fried to the bump. Luis Garcia will post at second base as the Nationals try to avoid being swept.

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. 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.
