Shaw is out of the lineup for Sunday's game against the Orioles.

Shaw had started at third base in seven straight games, but he'll cede the hot corner to Willi Castro on Sunday. Since the All-Star break, Shaw has produced a 1.014 OPS, but he'll need to maintain that improved level of production to stave off Castro for a regular spot in the lineup.

Riley was removed from Sunday's game against the Reds due to lower abdominal pain.

Sunday was slated to be an off day for Cincinnati and Atlanta, but the two clubs instead resumed Saturday's MLB Speedway Classic after the game was suspended in the first inning due to rain. Riley struck out swinging Saturday before the game was halted, and he was replaced by Luke Williams before coming up to the plate Sunday. The severity of the injury remains unclear, and Riley should be considered day-to-day heading into Monday's series opener versus Milwaukee. Given that Riley was reinstated July 25 following a stint on the injured list due to a lower abdominal strain, it's worrisome that he's seemingly dealing with a recurrence of the injury just over a week later.

Baty is out of the lineup for Sunday's game against the Giants.

Baty will head to the bench for the second time in the series, with both of his absences coming against left-handed starters. He could be at risk of losing out on starts versus right-handers, too, as Jeff McNeil will see more time in the infield after the Mets acquired center fielder Cedric Mullins from the Orioles on Thursday, giving Ronny Mauricio one fewer path to playing time. Baty, Mauricio and Mark Vientos will battle for starts at third base, but Mauricio's .886 OPS this season against righties is well ahead of Baty's .729 OPS in that split.

Mauricio is out of the lineup for Sunday's game against the Giants.

Mauricio will head to the bench while Mark Vientos starts at third base Sunday. The acquisition of Cedric Mullins at the trade deadline will limit Jeff McNeil to primarily second base, and in turn, Mauricio could be part of a committee at the hot corner with Vientos and Brett Baty.

House is out of the lineup for Sunday's game against the Brewers, Mark Zuckerman of MASNSports.com reports.

After tying a career high with three hits in a July 22 win over the Reds, House has fallen into a 5-for-30 skid at the plate while striking out 11 times over his last eight games. Jose Tena will step in at third base Sunday in place of House, who will hit the bench for the second time in four games amid his rough stretch at the dish.

Seigler will start at third base and bat seventh Sunday against the Nationals.

Seigler will make a second straight start in place of Caleb Durbin after going 1-for-4 with his second stolen base of the season in Saturday's 8-2 win. The Brewers haven't indicated that Durbin is dealing with an injury, so Seigler will likely return to a backup role during the upcoming week.

Durbin is out of the lineup for Sunday's game against the Nationals.

Durbin is on the bench for the second day in a row, but the Brewers have yet to indicate that his absence is the result of an injury. Anthony Seigler will pick up another start at third base at Durbin's expense after going 1-for-4 with a stolen base in Saturday's 8-2 win.

Muncy (knee) could return from the 10-day injured list as soon as Monday, Sonja Chen of MLB.com reports.

Muncy has gone 3-for-12 with a walk, a run and an RBI over four games during a rehab assignment with Triple-A Oklahoma City. After manning third base in those contests, Muncy is scheduled to serve as Oklahoma City's designated hitter Sunday, and the Dodgers will reassess him after the contest. Once he's cleared to return, Muncy should displace rookie Alex Freeland as the Dodgers' everyday third baseman.

Andujar is replacing Gavin Lux in Saturday's starting lineup against Atlanta, batting fifth and playing left field, Charlie Goldsmith of Fox 19 Now Cincinnati reports.

Lux was originally slated to start against righty Spencer Strider, but Strider was scratched as a result of a lengthy weather delay. Atlanta is now deploying lefty Austin Cox as an opener, and the Reds are countering by swapping in the righty-hitting Andujar for the lefty-hitting Lux.

Durbin isn't in the lineup for Saturday's game against the Nationals.

Durbin will catch a breather Saturday after going 3-for-6 with two runs scored during Friday's high-scoring victory. Anthony Seigler will replace him at the hot corner and bat eighth.
