I say it more because of who we are throwing out there.
In Tampa, we have Igawa and Wang throwing, 2 guys who are in the projected rotation for the team and 2 guys at least capable of going 6 or more.
In Toronto we are throwing Pettitte to start, who should give us a quality start vs a righty depleted lineup (no Glaus, no Johnson who OWNS us). The question mark is Karstens who could bounce back against their crappy lineup. So in all, I will assume that out of Pettitte, Wang, and Igawa, we get 19IP and from Karstens, at least 5. So we should average 6IP going into your series meaning that for 4 games, we will start getting some players rested prior to your series.
