Tate (forearm) will make his next four or so appearances with Double-A Bowie, Andy Kostka of TheBaltimoreBanner.com reports.
Tate made his first rehab appearance with High-A Aberdeen on Tuesday, allowing a run on two hits and striking out two in one inning. He's expected to need four or five more outings at a minimum, including two on back-to-back days, before he's ready to join the Orioles for his season debut.
