Orioles interim manager Tony Mansolino said Monday that Mountcastle will not be activated from the 60-day injured list during the team's series against the Phillies that runs through Wednesday, Jake Rill of MLB.com reports.

EDGE Analysis

Mountcastle is slashing .391/.440/.783 with two home runs and three doubles in his first six rehab games with Triple-A Norfolk, but he will remain in the minors for the time being. The Orioles begin a homestand Friday, and Mountcastle seems to have a good chance to return to the active roster that day. He's been shelved since late May with a right hamstring strain.

Orioles interim manager Tony Mansolino said that Mountcastle (hamstring) won't be reinstated from the 60-day injured list ahead of Monday's series opener in Philadelphia, Jake Rill of MLB.com reports.

EDGE Analysis

Before receiving Sunday off, Mountcastle had appeared in six rehab games for Triple-A Norfolk, making four starts at first base and two at designated hitter while slashing .391/.440/.783 with two home runs and three doubles. Though Mountcastle hasn't experienced any setbacks with his right hamstring during his assignment, Mansolino said that the Orioles want the 28-year-old to get some more at-bats in at Triple-A before he rejoins the big club for the first time since late May. Mountcastle may not be activated during the series with Philadelphia, but he still appears on track to return from the IL at some point during the upcoming week.

Mountcastle (hamstring) has gone 8-for-19 (.421) with two home runs, three doubles and six RBI over five games during his rehab assignment with Triple-A Norfolk.

EDGE Analysis

After spending two months on the shelf due to a right hamstring strain, Mountcastle appears to be on the verge of being activated from the injured list. The 28-year-old slugger is expected to spend the weekend in the minor leagues to wrap up his assignment, and the Orioles are likely to reinstate him ahead of Monday's series opener in Philadelphia if all goes well. Mountcastle should return to his role as Baltimore's primary first baseman upon his return, which would shift Ryan O'Hearn back into the outfield, and it remains to be seen how much playing time Coby Mayo will see down the stretch.

Mountcastle (hamstring) is not expected to be activated from the 60-day injured list until next week's series in Philadelphia, Jake Rill of MLB.com reports.

EDGE Analysis

Mountcastle has played three rehab games with Triple-A Norfolk and is eligible for activation Wednesday, but the Orioles will give him a little more time following a nearly two-month long absence due to a right hamstring strain. With Ryan O'Hearn a candidate to be traded ahead of Thursday's deadline, Mountcastle and Coby Mayo could be in line to share the first-base and designated-hitter spots for the Orioles down the stretch.

Orioles interim manager Tony Mansolino said that Mountcastle (hamstring) will begin a rehab assignment Thursday with Triple-A Norfolk, Brendan Mortensen of MASNSports.com reports.

EDGE Analysis

Mouncastle won't be eligible for activation until July 30, so he'll likely stick around in Norfolk through the next week to compile at-bats before the Orioles add him back to the roster. Before going down in late May with a right hamstring strain, Mountcastle had gotten off to a poor start to the season at the plate, batting just .246/.280/.348 with two home runs in 200 plate appearances. An everyday role may not be waiting for Mountcastle once he's reinstated, though his outlook for playing time would improve if the non-contending Orioles move impending free agent Ramon Laureano prior to the July 31 trade deadline.

Mountcastle (hamstring) is expected to begin a rehab assignment at Triple-A Norfolk on July 22, Rich Dubroff of BaltimoreBaseball.com reports.

EDGE Analysis

A Grade 2 right hamstring strain has kept Mountcastle on the injured list since the end of May. By beginning minor-league play July 22, the 28-year-old is still in a position to be activated when first eligible July 30, as he'll have more than a full week to ramp up in Triple-A.

Mountcastle (hamstring) said Friday that he began a hitting progression this week and is hoping to return once he's eligible for reinstatement July 30, Matt Weyrich of The Baltimore Sun reports.

EDGE Analysis

Mountcastle was given an 8-to-12 week return timeline, and he's trending toward being activated around the eight-week mark, having made significant strides in his recovery. The 28-year-old will have to avoid a setback, but he's on track for a late-July or early-August return.

The Orioles transferred Mountcastle (hamstring) from the 10-day injured list to the 60-day IL on Monday.

EDGE Analysis

After suffering a Grade 2 right hamstring strain in a May 30 game, Mountcastle was placed on the IL one day later. Though the Orioles never provided a firm timeline for Mountcastle's recovery, the veteran first baseman had been expected to miss around 8-to-12 weeks due to the moderate hamstring strain, so his move to the 60-day IL won't affect his return date. Ryan O'Hearn is poised to see the bulk of the starts at first base for the foreseeable future, with Coby Mayo occasionally mixing in.

Mountcastle was diagnosed with a Grade 2 right hamstring strain Friday, Jake Rill of MLB.com reports.

EDGE Analysis

Mountcastle's hamstring sent him to the 10-day injured list Saturday, but now that the severity of his injury has been revealed, he's expected to miss between 8-12 weeks. Even in a best-case scenario, the 28-year-old's absence will extend into August, but he still has a decent chance to make it back before the end of the regular season. Coby Mayo and Ryan O'Hearn have been splitting first-base duties since Mountcastle landed on the IL, and the pair will presumably continue to share starts going forward.

Interim manager Tony Mansolino said Wednesday that Mountcastle (hamstring) will be sidelined "a while" after the Orioles received his MRI results, Roch Kubatko of MASNSports.com reports.

EDGE Analysis

It's not an encouraging sign for Mountcastle, who remains without a definitive timetable for a return and appears to be out indefinitely due to a right hamstring strain. Baltimore recalled Coby Mayo from the minor leagues after Mountcastle hit the injured list, and the former looks to have a fairly clear pathway to at-bats either at first base or designated hitter for the time being. Ryan O'Hearn is also likely to be needed to handle additional reps at first base as opposed to the outfield while Mountcastle is on the shelf.
