It seems to me - at least in the WCWS - that Ellen is given enough rope to figuratively hang herself - and then some - but Ivy is taken out at the first sign of trouble. I would have considered bringing Ivy in in the 11th, but there is no way I would have ever had Ellen pitch the 12th. She was just too shaken up. You could tell by how she looked in the dugout in the top of the 12th and in the circle in the bottom of the inning.
I would agree in 99 percent of situations, but I would be hard pressed to find anybody who would not have been unnerved by what happened on that stage, even professionals.
Ivy absolutely has to pitch tomorrow. We can still win this, but we need a fresh face out there in the circle after what happened tonight.
