Yes. We should definitely be following the Tampa model of letting pitchers develop slowly through the system.
Before Bundy and Gausman the O's generally took their time as well.
Matusz was up here for a stint a year after he was drafted, but he was thought to be close to ML ready coming out of the draft and had simply dominated AA in two months of work.
Arrieta spent a full season in Frederick. A full season between Bowie and Norfolk and then another third of a season in Norfolk before getting the call.
Britton had spent a full season in Delmarva. Another full season in Frederick. And finally a full season between Bowie and Norfolk at which is pretty much dominated at both stops at age 22. He appeared fully ready and still held his own over a full season in Baltimore.
Chris Ray spent a full season between Delmarva and Frederick as a starter. He was then converted to a relief pitcher and spent half a season just dominating AA hitters before being called up. Relief pitchers don't generally need as much time in the minors so I won't say he was rushed.
David Hernandez, Brad Bergesen, and Garrett Olson all spent significant time in the minors before being called up.
Honestly, I'm not sure if it's a matter of the O's rushing prospects or that the prospects just aren't very good to begin with.
