I hope not. That would only water down the rotation. Right now, 60% of the starts will be Gausman, Manoah or Berrios....a small majority of the time...but still a majority. If you go to a 6 man rotation...it means that the big three only represent 50% of the starters other teams will face. I say go with the odds and stay with a five man rotation as much as you can.
IF the Jays decide to go with a 6 man rotation, I think it would be a HUGE mistake.
