Lee (back) was recalled from Double-A Bowie and placed on the 60-day disabled list, Roch Kubatko of MASN Sports reports.
Lee has been out since early June with this back issue, and since the Orioles needed a spot on the 40-man roster for Paul Janish, the top prospect was a logical choice to cast off the active roster. The left-hander will likely rehab over the offseason and get back to game action with one of the higher affiliates in the Orioles organization.
