Atlanta placed Riley on the 10-day injured list Monday with a strained lower abdominal muscle.

Riley spent a couple weeks on the injured list in July with an abdominal strain and is now back on the IL after aggravating the injury Sunday. He will be eligible for activation Aug. 14, but Atlanta will likely be more cautious with his recovery this time around. Nacho Alvarez was recalled from Triple-A Gwinnett to step in as the everyday third baseman.

Phillies manager Rob Thomson said that Bohm (rib) fielded ground balls and hit in the batting cage prior to Sunday's game against the Tigers, MLB.com reports.

Thomson noted that Bohm is pain-free as he works his way back from a fractured left rib and is drawing closer to beginning a rehab assignment. Since Bohm was placed on the injured list July 19, the Phillies have been getting by with a combination of Otto Kemp and Edmundo Sosa at third base.

Manager Brian Snitker said after Sunday's 4-2 win over the Reds in the MLB Speedway Classic in Bristol, Tenn. that Riley (abdomen) will be evaluated in the next day or two before Atlanta decides whether he requires a stint on the injured list, Mark Bowman of MLB.com reports.

After striking out in his lone plate appearance in the game that first started Saturday before it was resumed in the bottom of the first inning Sunday, Riley played two innings in the field before he was lifted for pinch hitter Luke Williams the next time his turn in the batting order came up in the top of the third. Atlanta later relayed that Riley was pulled from the game due to lower abdominal pain, an injury he appeared to suffer when he made a diving tag on Elly De La Cruz to prevent a run in the bottom of the first. Given that Riley was previously on the IL from July 12 through July 25 due to a lower abdominal strain, Riley could be dealing with a related setback that will result in another multi-week shutdown. If Atlanta decides to deactivate Riley, Nacho Alvarez would likely be recalled from Triple-A Gwinnett to take over as the team's everyday third baseman.

Kemp is out of the lineup for Sunday's game against the Tigers.

Edmundo Sosa will step in at third base while Kemp sits for the second time in the series. Kemp has maintained a .773 OPS since the All-Star break and still looks to be the Phillies' preferred option at the hot corner while the team waits for Alec Bohm (rib) to return from the injured list.

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.
