Unless something changes in the next few days it is looking like he will miss 1 start at most. Factoring in the off day there isn't really a need for 5 starters right off the bat so no reason for the DL I guess.
Should've clarified starters:
C Quintero (Catchers will split time, but Quintero is always paired with Opening Day starter Myers so I listed him)
1B Wallace
2B Hall
SS Sanchez
3B Johnson
LF Lee
CF Bourn
RF Pence
SP: Myers, Rodriguez, Happ, Norris, Figueroa
