Manaea (shoulder) is scheduled to start Monday's series opener with the Mariners, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

All systems are go for the young southpaw, as the Athletics have already cleared a rotation spot for him after optioning Jharel Cotton back to Triple-A. This development would line Manaea up to square off against Yovani Gallardo in Seattle.

Manaea (shoulder) is expected to be activated from the disabled list Sunday or Monday, Susan Slusser of the San Francisco Chronicle reports.

EDGE Analysis

It appears Manaea is ready to rejoin the Athletics after tossing a four-inning rehab game at Triple-A Nashville on Tuesday. He allowed just one run and struck out five during that outing. The 25-year-old held a 5.18 ERA through 24.1 innings (five starts) before landing not he disabled list. He'll likely take the rotation spot of Jharel Cotton, who was optioned back to Triple-A Thursday.

Manaea (shoulder) may need to throw one more rehab game before coming off the DL, Jane Lee of MLB.com reports.

EDGE Analysis

Manaea was solid during Tuesday's rehab start at Triple-A Nashville. Over four innings he allowed just one run and struck out five batters. Manager Bob Melvin reported that Manaea felt good during Tuesday's outing, but it's possible that the club will want him to throw in one more game before bringing him off the DL.

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.

EDGE Analysis

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.

Manaea (shoulder) was placed on the 10-day disabled list Sunday.

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.

Manaea (shoulder) is not likely to make his next scheduled start and could land on the disabled list, NBC Sports Bay Area's Joe Stiglich reports.

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.
