Manaea (shoulder) threw a 20-pitch bullpen session Tuesday, his first since last September's surgery, Martin Gallegos of MLB.com reports.

EDGE Analysis

Manager Bob Melvin remarked that Manaea's session consisted solely of fastballs and went off without a hitch. It's an encouraging first step in what's expected to be a relatively extensive rehab process for the southpaw, and he'll likely repeat the process at some point toward the end of the week.
