Atlanta transferred Riley (abdomen) from the 10-day injured list to the 60-day IL on Monday.

EDGE Analysis

The transaction frees a spot on the 40-man roster for the addition of Ha-Seong Kim (back), who was claimed off waivers from the Rays on Monday. Riley underwent season-ending core surgery nearly two weeks ago and is expected to be ready for spring training.

Atlanta announced Thursday that Riley (abdomen) underwent season-ending core injury surgery.

EDGE Analysis

Riley is expected to be ready for the start of spring training in February. The third baseman has been out since Aug. 2 and had been experiencing soreness in his abdominal area, as he tried to rehab and play again this season. With surgery out of the way, Riley's 2025 season comes to a close with a .260/.309/.428 slash line, 16 home runs, 54 RBI, 54 runs scored, two stolen bases and a 27:128 BB:K across 447 plate appearances. Now that he's done for the year, Riley will have missed a total of 112 games over the past two seasons.

Riley (abdomen) felt more soreness during a workout Tuesday and is not expected to be activated from the 10-day injured list anytime soon, Gabe Burns of The Atlanta Journal-Constitution reports.

EDGE Analysis

Riley has been sidelined for most of August with a strained lower abdominal muscle and continues to feel discomfort each time he attempts to ramp up activities. With Atlanta out of playoff contention, the club has little incentive to push its third baseman back onto the active roster. Consider Riley out indefinitely. Nacho Alvarez will continue to occupy the hot corner in Riley's absence.

Riley ran the bases Sunday but still felt some abdominal discomfort, Mark Bowman of MLB.com reports.

EDGE Analysis

He will run again Tuesday, but a timeline for Riley's return to the Atlanta roster remains unclear. Riley has been sidelined for most of this month with a strained lower abdominal muscle. Nacho Alvarez will continue filling in at third base for Atlanta until Riley is ready to return from the injured list.

Riley (abdomen) still felt discomfort while throwing Tuesday, Mark Bowman of MLB.com reports.

EDGE Analysis

Riley is eligible to come off the 10-day IL on Friday, but the expectation is that he's going to need more time to recover from his abdominal strain. Nacho Alvarez has been handling the bulk of the third-base duties for Atlanta while Riley has been sidelined.

Riley (abdomen) likely won't need a rehab assignment before rejoining Atlanta's lineup, David O'Brien of The Athletic reports.

EDGE Analysis

Manager Brian Snitker wouldn't offer a guess as to when the third baseman might be activated from the IL, but Riley's not expected to be too far behind Ronald Acuna (calf), who should rejoin the lineup before the end of the week. Riley has been sidelined since Aug. 2 after aggravating an abdominal strain that had previously cost him eight games sandwiched around the All-Star break. It's been a disappointing season overall for the 28-year-old, whose .737 OPS would be his lowest mark since he became a full-time player in 2021.

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

EDGE Analysis

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.

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.

EDGE Analysis

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.

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

EDGE Analysis

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.

Riley went 2-for-6 with a homer, a double, and four RBI in Monday's 10-7 victory at Kansas City.

EDGE Analysis

The Atlanta third baseman clubbed a 422-foot solo shot off Royals reliever Sam Long to tally his first long ball since returning from an abdomen injury July 25. Riley also cleared the bases with his 20th two-bagger of the season in the eighth to notch his fourth game with four or more RBI this season. Through 427 total plate appearances, the two-time All-Star is slashing .268/.319/.437 with 15 homers, 52 RBI and 52 runs scored in 97 games.
