Voth was added to Washington's 40-man roster on Friday, MASN's Dan Kolko reports.
As expected, the Nationals protected Voth from the Rule 5 draft. His minor league numbers are excellent, but it is a No. 5 starter's profile, as his fastball is just average and he lacks a plus pitch. Voth could be used as an emergency big league starter in 2017, although Lucas Giolito, Reynaldo Lopez and A.J. Cole are all likely ahead of him on the organizational depth chart.
