How successful are the Orioles at developing starting pitchers since Peter Angelos took over? This question has urgency for O's fans, with Brian Matusz, Jake Arrieta, Zach Britton, Dylan Bundy, and Kevin Gausman -- all of whom were drafted by the Orioles -- in various stages of our development system. As a gut feeling, it's tough for me to be optimistic, but I wanted to see the data for myself.

To do this, I searched for AL East pitchers who meet all of the following criteria:

Had at least one season since 1994 in which they both started at least 60% of their games and qualified for the ERA title. To simplify, I counted 1994 and 1995 as whole seasons.
Were drafted, or signed as an amateur free agent, by the same team after 1994, which was Peter Angelos's first season.
Spent some time in their team's minor league system.
