Manaea (shoulder) will begin a rehab assignment with Triple-A Nashville on Tuesday.

EDGE Analysis

The young southpaw completed a bullpen session Saturday, and it appears that the Athletics' brass feels confidently enough to bump him back into game action quickly. Manaea is slated to "pitch in tandem" with fellow rehabbing starter Chris Bassitt (elbow), although the exact pitch count for the two of them is unclear at this time.

Manaea (shoulder) threw a 36-pitch bullpen session Saturday and he was pain free, the San Francisco Chronicle's Susan Slusser reports.

This is excellent news, as he had to throw long toss instead of a bullpen session Thursday due to a bit of soreness, but now things seem to headed back in the right direction. It is unclear whether he will need a rehab assignment before returning to the rotation.

Manaea (soreness) will throw long toss instead of a bullpen session Thursday after reporting a bit of soreness, Susan Slusser of the San Francisco Chronicle reports. This may hold back his return from the disabled list.

EDGE Analysis

His absence was initially expected to be brief, but the Athletics will want to be cautious with this development. Manaea's timetable will become clearer in the next few days, while Sonny Gray is now expected to take his turn May 7, when it was originally thought Manaea would be activated.

Manaea (shoulder) is scheduled to throw a bullpen session Thursday, MLB.com's Jane Lee reports.

EDGE Analysis

Manaea was expected to miss just one start after being placed on the 10-day disabled list with a shoulder strain. Thursday's bullpen will be a good test to see if he remains to return when he is eligible, which could be as soon as May 7 against the Tigers.

Manager Bob Melvin confirmed that Manaea (shoulder), who was placed on the 10-day disabled list Sunday, would only miss one turn in the rotation, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

The Athletics were already set to activate Sonny Gray (back) from the DL on Tuesday to give the team five healthy starters, so it was an easy decision for manager Bob Melvin to temporarily shelve Manaea and grant him some additional time to recover from the left shoulder strain. Manaea is expected to throw a side session in the coming days, and if all goes well, he'll likely come off the DL when immediately eligible May 7 to make a start against the Tigers. Jharel Cotton or Jesse Hahn would be most at risk of losing his rotation spot once Manaea is activated.

EDGE Analysis

The Athletics were already anticipating that Manaea would miss his next scheduled start after he strained his left shoulder during his last outing Wednesday against the Angels, so the team will opt to move him to the DL to create some roster flexibility. It's unclear if Manaea will miss more than one start due to the injury, but further word on that front should arrive when the team evaluates the left-hander over the next few days. It's expected that Sonny Gray (back), who is set to return from the DL on Tuesday, will replace Manaea in the rotation.

EDGE Analysis

It seemed like Manaea might be able to rejoin the rotation in the coming days, but it now looks like a DL stint could be in the cards. Assuming Manaea is unable to make Tuesday's start against the Twins, Sonny Gray will likely take the ball, with Kendall Graveman starting Wednesday.

The promising young lefty had an early exit from his outing Wednesday due to tightness in his throwing shoulder. Fortunately, early reports on Manaea's shoulder have been positive and the tightness has subsided to the point where he can resume throwing just two days after the flare-up. After Manaea's throwing session, the A's figure to have a clearer picture as to when the southpaw will be ready to return to the rotation.

Manaea (shoulder) hopes to participate in throwing exercises Friday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

If Manaea is able to throw Friday, it should be much easier to determine when he'll be ready to return to live action. Manaea, who was diagnosed with shoulder tightness, passed initial strength tests, so it would appear that he's not dealing with a more problematic ailment.

Manaea's shoulder tightness has started to subside since flaring up during Wednesday's outing, Jane Lee of MLB.com reports.

EDGE Analysis

At this point in time, there are no plans for Manaea to undergo tests to see if he's dealing with a more serious injury. Although he's still being considered day-to-day, the A's have yet to rule out the possibility of Manaea making his next scheduled start, which would be Tuesday against the Twins.
