PITCHERS
RHP Drew Anderson (23): He has less experience than any pitcher on the 40-man roster, but his stock rose since Tommy John surgery two Aprils ago.
RHP Mark Appel (25): It's a make-or-break season for Appel, the former No. 1-overall pick. He needs to show progress at triple-A Lehigh Valley.
RHP Alec Asher (25): He could fill the unglamorous but essential role of swingman, bouncing between the bullpen and rotation when needed.
RHP Joaquin Benoit (39): His fastball averaged 94.
