Karros isn't in the lineup for Saturday's game against the Angels, Thomas Harding of MLB.com reports.

Karros went 1-for-3 with a walk and a strikeout in Friday's win and will now get a chance to rest against Kyle Hendricks and the Angels. Orlando Arcia will fill in at the hot corner and bat ninth.

Muncy (hand) was activated from the 10-day injured list prior to Saturday's game against the Pirates.

Muncy has been on the shelf since July 21 due to a hairline fracture at the base of the fourth metacarpal in his right hand and did not go on a rehab assignment, instead going through a hitting progression on the side. Zack Gelof (dislocated shoulder) was placed on the injured list in a corresponding move. Muncy should get some starts at third base and the keystone over the final eight games of the season, although he is on the bench Saturday.

Vientos is not in Saturday's lineup against the Nationals.

The 25-year-old third baseman had started 12 of the last 14 games, with his two off days coming against righties. Vientos is hitting .179 with two home runs and 19 strikeouts in 17 games this month. Brett Baty will man the hot corner while Starling Marte gets the start at designated hitter against righty Cade Cavalli.

Chapman went 2-for-5 with a double, an RBI and a run scored in Friday's 6-3 loss to the Dodgers.

Following a five-game stretch in which he went 0-for-15 across 20 plate appearances, Chapman lined a double to center field in the second inning before coming around to score. He also added an RBI single in the seventh. The third baseman owns a .236/.347/.442 slash line with 72 runs scored, 59 RBI, 21 long balls and nine stolen bases across 505 plate appearances in 121 games this season.

Bregman went 1-for-3 with two walks and a solo home run in Friday's 11-7 win over the Rays.

Bregman homered for the second time this week, but he's struggled at the plate over the last several weeks. He has a .597 OPS with two homers and 10 RBI over the last 33 games.

Ramirez went 1-for-3 with a walk, a double, a steal and two runs scored in Friday's 6-2 win over the Twins.

Ramirez walked and scored in the first inning before he doubled and scored the go-ahead run in the eighth. He's scored runs in five consecutive games, crossing home plate seven times while going 6-for-18 with five walks, three steals, one home run and three RBI. Ramirez also stole a base in the eighth inning, upping his season total to 40, his second consecutive season with at least 40 steals.

Shaw went 2-for-4 with a double and a two-run home run in Friday's 7-4 loss to the Reds.

Shaw had been in a bit of a power drought, as this was his first home run since Aug. 20, giving him 12 for the season. While the rookie came out of the All-Star break on a hot streak, he has cooled down more recently. Since the beginning of August, Shaw is batting just .222 and he's striking out nearly 24 percent of the time. He should continue to see regular playing time now that the Cubs have clinched a playoff spot, but the team may be less patient in the postseason if Shaw slumps.

Lewis went 2-for-4 with a stolen base and an RBI in Friday's 6-2 loss to Cleveland.

Although it's been a lost season for the most part for Lewis -- he has a .680 OPS in 2025 -- it's certainly an encouraging sign to see how active he's been on the basepaths lately. The oft-injured third baseman has 11 of his 12 steals for the year over his last 25 outings, which signals that he's fully healthy as the campaign draws closer to an end. Lewis is flashing the upside that made him the No. 1 overall pick back in 2017, hitting .275 and slugging .461 with seven extra-base hits and 19 RBI over his last 102 at-bats.

Vargas went 1-for-3 with a two-run home run and a walk in Friday's 4-3 victory over San Diego.

The Chicago infielder opened the contest's scoring with a 371-foot, two-run blast off Padres starter Dylan Cease in the first. Prior to this performance, Vargas had struggled over eight games since returning from a hand injury Sept. 10, batting .115 (3-for-26) with eight strikeouts and no walks. The 25-year-old is now slashing .228/.309/.397 with 73 runs scored and 55 RBI in 534 total plate appearances.

The Tigers recalled Jung from Triple-A Toledo on Friday.

Jung will join the active roster in place of Colt Keith (ribs), who's headed to the injured list. Jung will compete with Zach McKinstry and Andy Ibanez for playing time at third base.
