You have a rookie coming up in 2 spots that is a much better candidate to be pinch hit for against a lefty, plus Turner was already going to have to go in the game to play defense at 1B.
They'd have to do that Monday for it to really make a difference in rest for anyone and unless you get like 6 innings out of Jamo in game one, that seems like a risky play that could decimate your pen for the rest of the series if it doesn't go well.
