Riley is out of the lineup for Sunday's game against the Diamondbacks, Chad Bishop of The Atlanta Journal-Constitution reports.

EDGE Analysis

It's the first day off of the season for Riley, who is batting .103 (3-for-29) with nine strikeouts in eight games since collecting three hits Opening Day. Mauricio Dubon will shift to the hot corner while Jorge Mateo picks up a start at shortstop in Sunday's series finale at Arizona.

Riley went 3-for-3 with a walk and a run scored in Friday's win over the Royals.

EDGE Analysis

While all of the third baseman's hits were singles, it was still an impressive start to the season. Riley has seen his offensive production decline the last two years as he struggled to stay healthy, but if he stays in the lineup the 28-year-old is more than capable of returning to the level he established in 2021-23, when he averaged 36 homers and 99 RBI a year with a .286/.354/.525 slash line.

Riley went 3-for-4 with two doubles, a home run and four RBI in Saturday's Grapefruit League game against the Red Sox.

EDGE Analysis

The long ball wasn't a cheap one -- Riley got hold of a Garrett Crochet cutter in the second inning and put it over the ersatz Green Monster at JetBlue Park. It was Riley's fifth homer of the spring, and the third baseman knocked both his doubles off Boston's ace as well. Over 15 Grapefruit League games, Riley is batting .395 (15-for-38) with a 6:8 BB:K, and he looks more than ready for Opening Day.

Riley could be surprisingly active as a base stealer this season under the tutelage of new Atlanta baserunning coach Antoan Richardson, Mark Bowman of MLB.com reports.

EDGE Analysis

Richardson was the man most responsible for Juan Soto's stunning 38-steal campaign last season, and while Riley has only seven career stolen bases in seven MLB seasons, he's not actually slow of foot -- his sprint speed in 2025 ranked in the 73rd percentile. "He's going to get 20," center fielder Michael Harris said Friday. Riley was successful on his only steal attempt of the spring so far, but until he actually shows more willingness to use his legs, any contribution he makes in steals should be viewed as a bonus by fantasy GMs.

Riley went 1-for-2 with a two-run home run in Atlanta's Grapefruit League game against the Pirates on Wednesday.

EDGE Analysis

The third baseman took Jarod Bayless deep in the third inning, taking advantage of Paul Skenes' exit two batters prior. Riley was fully healthy for the first time in a while this offseason, and he's looking to rebound after a couple tough campaigns that saw him hit just 35 homers in 212 regular-season games with a .760 OPS -- a sharp decline for the 28-year-old after he belted 75 long balls with an .869 OPS in 2022-23 while missing only six games in total.

Riley didn't have any limitations this offseason and worked with Atlanta hitting coach Tim Hyers on finding his old swing, Mark Bowman of MLB.com reports.

EDGE Analysis

The third baseman underwent sports hernia surgery in early August that ended his 2025 campaign prematurely, but he was fully recovered in time to get back to his normal offseason routine. That's a marked contrast to the previous offseason, when hand surgery left Riley in a cast until January and had him playing catchup during spring training. While he missed a total of 112 regular-season games over the prior two seasons, Riley appears to be in good shape to regain the form that saw him average 36 homers, 99 RBI and 159.3 games played from 2021-23.

Riley (core) took live batting practice Wednesday and appears to be facing no restrictions for the start of spring training, Mark Bowman of MLB.com reports.

EDGE Analysis

Riley appears to be 100 percent healthy after he missed most of the final two months of 2025 with a lower abdominal strain, which he ultimately addressed via core-muscle surgery Aug. 21. Though his reputation as one of baseball's more durable third basemen has taken a hit after two straight injury-shortened seasons, Riley won't turn 29 years old until April, and with some better luck on the health front, he could re-emerge as the consistent 30-homer, 90-RBI producer that he was from 2021 through 2023.

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.
