Harvey was optioned to Triple-A Norfolk on Sunday, Roch Kubatko of MASN Sports reports.
Harvey started nine games (32.1 innings) for Double-A Bowie in 2018 with a 5.57 ERA and 1.40 WHIP, so there was no guarantee he would be promoted to start this season. The 24-year-old has been limited to 63.2 innings since 2014 due to injuries but could seemingly find his way to the majors in 2019 if he showcases well at Norfolk.
