Karros is out of the lineup for Thursday's contest versus the Dodgers.

Karros will miss a second straight start while he deals with back tightness. He's considered day-to-day and will attempt to return to the lineup sometime over the weekend in Pittsburgh. Orlando Arcia will man the hot corner and bat eighth for the Rockies on Thursday.

Jung is out of the lineup for Thursday's game against the Royals.

After starting at third base and going 0-for-2 in Wednesday's 6-3 win while lefty Noah Cameron was on the hill for Kansas City, the right-handed-hitting Jung will head back to the bench as the Royals send righty Michael Lorenzen to the bump for the series finale. Jung has now been held out of the lineup for four straight matchups versus righties and looks to have moved into a platoon role after slashing just .163/.217/.279 so far in August. Cody Freeman will draw the start at the hot corner Thursday, but super-utility player Josh Smith is more likely to occupy the strong side of a platoon at third base with Jung once right fielder Adolis Garcia (ankle) returns from the injured list.

Shaw is not in the lineup for Thursday's contest versus the Brewers.

Shaw slugged his 11th home run of the season in Wednesday's 4-3 victory but will get a breather in Thursday's series finale. Willi Castro will man third base and bat seventh for the Cubs.

Arcia went 1-for-2 with a walk, two RBI and two runs scored Wednesday against the Dodgers.

Arcia drew the start at third base with Kyle Karros (back) sidelined, and he's now been in the lineup twice across four games since being activated from the injured list. He drew his two RBI with a sacrifice fly and an infield single and also tallied an insurance run in the sixth inning. Assuming Karros is able to avoid the injured list, Arcia will likely shift to a bench role moving forward.

Baty went 1-for-3 with a walk and a solo home run in Wednesday's 5-4 loss to the Nationals.

Starting at third base and batting seventh, Baty took Brad Lord deep in the fifth inning to get the Mets on the board as they attempted to rally from an early 4-0 deficit. Baty has homered four times in his last eight games, hitting .370 (10-for-27) over that stretch with a steal, six runs and six RBI while seizing an everyday role in the lineup between the hot corner and the keystone.

Jung started at third base and went 0-for-2 in Wednesday's 6-3 win over Kansas City.

Jung returned to the starting lineup after getting a three-game break, but his night ended after five innings. Josh Smith entered as a pinch hitter in the sixth against right-handed reliever Taylor Clarke. It looked like a brief July stint in the minors had straightened out Jung, who went 13-for-34 (.382) with four walks, three home runs, eight RBI and eight runs scored over his first 11 games back in the majors. Since then, however, the third baseman is batting .128 with two walks and two RBI over 12 games.

Machado went 1-for-4 with a solo home run in an 8-1 win against the Giants on Sunday.

Machado flashed his power with a 425-foot solo blast in the third inning. The long ball was his first since July 29 -- a span of 19 games. The veteran third baseman had only four RBI during that homerless span, and the Padres could really benefit if he's able to turn things around down the stretch. Despite the recent struggles, Machado still has a healthy 21 home runs and 74 RBI on the campaign, and his .837 OPS is on pace to be his best mark since 2022.

Moncada went 1-for-4 with a solo home run in a 2-1 win against the Reds on Wednesday.

Offense was sparse on both sides, and Moncada hit the only homer in the contest with a solo shot to center field in the fourth inning. The long ball snapped a 20-game homer drought for the third baseman dating back to July 19. Moncada batted a meager .208 with 19 strikeouts during that rough stretch, though he may be turning things around -- over his past eight contests, he's batting .333 (8-for-24) with three extra-base hits and four RBI.

Shaw went 1-for-2 with a walk, a solo home run and an additional run scored in Wednesday's 4-3 win over the Brewers.

Shaw has been on a nice run since the All-Star break, as he's now batting .302 with nine home runs, 17 runs scored and 18 RBI across his last 30 games. The rookie third baseman has put some early season struggles behind him, and with the Cubs not acquiring anyone to replace Shaw at the hot corner before the trade deadline, he should be locked into a regular role down. The 23-year-old's fantasy value is trending upward based on his strong recent performance and fairly consistent playing time.

Rockies interim manager Warren Schaeffer said that Karros is out of the lineup for Wednesday's game against the Dodgers due to back tightness, Patrick Lyons of JustBaseball.com reports.

The injury doesn't appear to be severe and Karros should be considered day-to-day for the time being. He'll be available off the bench as an emergency option while Orlando Arcia starts at third base and bats eighth. Karros has gone 10-for-37 (.270 average) with one home run, five RBI and 10 runs in 12 games since being called up from Triple-A Albuquerque on Aug. 8.
