Orioles manager Tony Mansolino said Sunday that Eflin received an injection to address his lower-back discomfort, Danielle Allentuck of TheBaltimoreBanner.com reports.

EDGE Analysis

Eflin is on the injured list for the second time in the past two months due to the back issue, which resurfaced after he made just two starts for Baltimore following his return from the IL. The Orioles are hoping that the injection will provide Eflin with some more permanent relief, but Mansolino noted that the right-hander is without a timeline to resume throwing. Given the Orioles' standing as non-playoff contenders, Eflin will likely be brought along deliberately even once he's cleared to start throwing again.

The Orioles placed Eflin on the 15-day injured list Thursday due to low-back discomfort.

EDGE Analysis

Eflin will hit the shelf for the third time this season and for the second time in just over a month due to continued back problems. After being reinstated last week, Eflin made just two starts for the Orioles before suffering an apparent setback. Baltimore recalled right-hander Brandon Young from Double-A Chesapeake in a corresponding move, and he or the rehabbing Cade Povich (hip) could be called upon to replace Eflin in the rotation the next time his turn comes up.

The Orioles are expected to place Eflin on the 15-day injured list Thursday, Ken Rosenthal of The Athletic reports.

EDGE Analysis

The report doesn't specify what kind of injury Eflin is dealing with, but he just returned from a back issue last week after missing nearly a month of action. Rosenthal relays that it's "very possible" Eflin is still traded ahead of Thursday's deadline even though he's hurt, as he is expected to be back before the end of the season. The veteran righty holds a 5.93 ERA, 1.42 WHIP and 50:13 K:BB across 71.1 innings this season.

Eflin did not factor into the decision in Monday's 11-4 win over the Blue Jays, allowing four runs on eight hits and one walk with three strikeouts over 4.1 innings.

EDGE Analysis

Eflin threw 56 of 79 pitches for strikes but managed just six whiffs while giving up nine hard-hit balls, including two homers in the third inning. Some rust is understandable in his second start back from the injured list, but it marked the fifth time in 14 outings the 31-year-old has allowed multiple home runs. He'll carry a 5.93 ERA, 1.42 WHIP and 50:13 K:BB across 71.1 innings into a tough road matchup with the Cubs this weekend.

Eflin didn't factor into the decision Wednesday against the Guardians, allowing two runs on two hits and one walk in five innings. He struck out five.

EDGE Analysis

Eflin was sharp in his first start since returning from the injured list, and he experienced smooth sailing until the Guardians brought in a pair of runs in the fourth inning. The veteran right-hander managed to toss 84 pitches, and he also generated a respectable 10 whiffs. Eflin owns a 5.78 ERA, 1.37 WHIP and 47:12 K:BB over 67 innings, and he'll aim to further increase his pitch count in his next scheduled appearance versus the Blue Jays.

The Orioles activated Eflin (back) from the 15-day injured list Wednesday.

EDGE Analysis

Eflin will rejoin the Orioles rotation Wednesday with a start against the Guardians after being sidelined nearly a month due to lower-back discomfort. The veteran right-hander threw 68 pitches over four innings in his final rehab outing in the rookie-level Florida Complex League last Friday, so Eflin will be somewhat limited from a workload perspective Wednesday.

Interim manager Tony Mansolino said Eflin (back) will be reinstated from the injured list to start Wednesday against the Guardians, Andy Kostka of TheBaltimoreBanner.com reports.

EDGE Analysis

The veteran right-hander has been sidelined nearly a month due to lower-back discomfort but is ready to rejoin the O's after making two rehab starts in the minors. Eflin threw 68 pitches over four innings during the second rehab outing and is likely to face some workload limitations in his first start back with Baltimore.

Eflin (back) struck out five and allowed five unearned runs on three hits and one walk over four innings in a rehab start Thursday in the rookie-level Florida Complex League.

EDGE Analysis

The appearance in the FCL was the second of Eflin's rehab assignment, which he kicked off last Sunday with a four-inning, 58-pitch outing for Double-A Chesapeake. He tacked on an additional 10 pitches to his workload Thursday, then said Friday that he feels good physically and believes he's ready to return from the 15-day injured list, according to Jake Rill of MLB.com. If the Orioles concur with Eflin's assessment of his health, he could step back into the big-league rotation for Wednesday's game in Cleveland.

Eflin (back) will continue his rehab with the Orioles' Florida League Complex team, Jake Rill of MLB.com reports.

EDGE Analysis

Eflin threw 58 pitches in a rehab start Sunday and, as planned, will continue his throwing progression in Florida. He's slated to rejoin the Orioles' rotation early next week for his first MLB action since suffering a back injury June 28. His return will likely bump Brandon Young out of the rotation.

Eflin (back) made a minor-league rehab start for Double-A Chesapeake on Sunday, allowing two runs on five hits and one walk in four innings. He struck out two.

EDGE Analysis

Eflin tossed 58 pitches in what may have been the only rehab outing he'll need during his recovery from a back strain, and he's next scheduled to continue his throwing progression in Florida on Friday. Although the 31-year-old right-hander won't be ready to rejoin Baltimore's rotation for Friday's second-half opener in Tampa Bay, he should be able to return shortly thereafter. Brandon Young appears to be the most likely candidate to head back to the minor leagues once Eflin is activated from the injured list.
