The deadline for MLB clubs to add players to their respective 40-man rosters in order to protect them from the Rule 5 Draft was Monday night. With that in mind, the Cardinals have purchased the contracts of:
Austin Gomber (LHP, ranked fifteenth in the organization by MLB.com and Eric Longenhagen of Fangraphs )
Derian Gonzalez (RHP, twenty-third by Fangraphs)
Tyler O’Neill (Outfielder, fourth by MLB.com, seventh by Fangraphs)
Oscar Mercado (Outfielder, eighteenth by MLB.com, sixteenth by Fangraphs)
This brings the Cardinals 40-man roster total to thirty-nine.
