Manaea (oblique) will begin a rehab assignment with High-A Brooklyn on Friday, Anthony DiComo of MLB.com reports.
EDGE Analysis
Manaea is slated to throw around 35 pitches in what will be his first game action since last year's postseason. The left-hander will continue to build up his pitch count and likely move to a higher affiliate, with the goal of rejoining the Mets' rotation in late June or early July.
