number 2 what?? If Perez is our number 2, we are screwed. He's only number anything because of Cashner, Griffin, Hamels, Ross, and Darvish being hurt during the season.
I'd make him a lefty specialist if on my team.
SP's should be
Darvish
Hamels
Ross
Cashner
Martinez or Dirkx
Just my opinion, of course.
