Manaea (shoulder) is scheduled to throw in a simulated game at Oakland's minor-league facility in Arizona on Saturday, Martin Gallegos of MLB.com reports.
The sim game will be yet another pivotal step in the recovery process for Manaea, who most recently threw a successful batting practice session. If all goes off without a hitch Saturday, Manaea could be ready to embark on a minor-league rehab assignment, although manager Bob Melvin also left open the possibility that the southpaw logs at least one more sim game.
