Riddle was placed on the minor-league injured list Tuesday with back spasms, Wells Dusenbury of the South Florida Sun Sentinel reports.

EDGE Analysis

Riddle has seen action at center field and shortstop since being demoted in mid-April, but has only played in five games as he also dealt with a jammed finger. The 27-year-old will be eligible to be activated next week, though it's unclear if he'll additional time to get healthy.

Riddle has played a few innings in center field since his demotion to Triple-A New Orleans, Andre Fernandez of The Athletic reports.

EDGE Analysis

While he's still primarily playing shortstop for the Baby Cakes, a transition to a utility role -- or at least showing the ability to handle center on an emergency basis -- could get Riddle back to the majors more quickly. It also might reflect the organization's frustration with Lewis Brinson's continued struggles and a lack of internal alternatives to replace him in Miami, should they decide a demotion is in order for him as well. Wherever he plays, Riddle is at least getting it done at the plate, hitting .353 in five games for New Orleans with a homer and six RBI.

Riddle was sent to Triple-A New Orleans on Tuesday, Joe Frisaro of MLB.com reports.

EDGE Analysis

Riddle is batting just .156 through 15 games to begin 2019, so the Marlins will give him some at-bats at a lower level. Miami purchased the contract of Isaac Galloway and recalled Jarlin Garcia from Triple-A in corresponding moves.

Riddle remains on the bench Friday against the Phillies, Andre Fernandez of The Athletic reports.

EDGE Analysis

Riddle and Miguel Rojas appeared to be in a strict platoon early in the season, with Riddle starting against every righty and Rojas getting the nod against every lefty through the first 11 games of the season. Since then, it's been Rojas in the lineup against three straight righties, including Jake Arrieta on Friday.

Riddle is out of the lineup for Thursday's game against the Reds, Mark Sheldon of MLB.com reports.

EDGE Analysis

Riddle has regularly started at shortstop against right-handed pitchers this season, so his absence from the lineup is somewhat surprising with Sonny Gray on the bump for Cincinnati. It's possible Riddle's hold on the top job has loosened in light of his 4-for-23 start to the season.

Riddle is not in the lineup Wednesday against the Reds.

EDGE Analysis

Riddle is just 4-for-23 with nine strikeouts through 10 games this season, so he'll find a seat on the bench Wednesday despite having the platoon advantage against righty starter Tyler Mahle. Miguel Rojas will start at shortstop and hit second in his place.

Riddle is not in the lineup for Sunday's game against the Braves, Joe Frisaro of MLB.com reports.

EDGE Analysis

Riddle returns to the bench as left-hander Sean Newcomb receives the start for Atlanta. Miguel Rojas will lead off and start at shortstop in his absence.

Riddle remains on the bench Tuesday against the Mets.

EDGE Analysis

Riddle has been on the bench for four of the Marlins' first six games, but that appears to be simply because the Marlins keep running into left-handed starters. Miguel Rojas will get the call again with Jason Vargas on the mound.

Riddle is not in the lineup Monday against the Mets, Andre Fernandez of The Athletic reports.

EDGE Analysis

As has been the case this season, Riddle will retreat to the bench with a southpaw (Steven Matz) toeing the rubber for the opposition. Miguel Rojas will start at shortstop and hit leadoff in his stead Monday.

Riddle went 1-for-3 with a solo home run in a 3-0 victory against the Rockies on Sunday.

EDGE Analysis

The 27-year-old hit just nine homers in 308 at-bats last season, but he's already got two through four games in 2019. In fact, his only two hits have gone over the fence. Riddle had one home run in spring training too but hit just .180 in 50 at-bats.
