Smith was added to Baltimore's 40-man roster Friday, Nathan Ruiz of The Baltimore Sun reports.
It was a tale of two seasons for Smith, as he logged a 1.04 ERA in 26 innings at Double-A and a 6.23 ERA in 56.1 innings at Triple-A. He struck out well over a batter per inning at both stops, but his command needs work for him to stick as a starter.
