"As we continue to construct a deep and flexible roster, Shae and Mallex add to our potential big league mix," Dipoto said. "Shae has had success pitching at the back end of games in the minors and has shown strikeout ability at all levels. Smith adds to our growing inventory of multi skilled, athletic outfielders. Both players are young, controllable and have bright futures."
